Old Winco Dyna Generator (Part 2 ) - Engine Rebuild on a Briggs L-Head Engine

This is part 2 on this generator. First video was spent getting the engine running and verifying that the generator head worked. The engine however was not producing the rated 8 house power. Instead it was closer to 3 HP. Will rebuild the engine to restore the lost power.

I really enjoyed this video, along with part 1. I love the fact that you are a "regular Joe" trying to fix something, you don't have a shop filled with a load of specialist tools and equipment. It means there's hope that anyone armed with a few basic tools can fix stuff like this. A lot of people would have thrown it on the scrapheap but you stuck with it... well done James, well done!!! 👏👏👏👏👏

[@jcondon1]

Thanks. Unfortunately even fixing it myself probably cost me more then it is worth. Most would have trashed it if faced with sending it to a shop where it would have cost a lot in labor. But I did enjoy it and learned a lot.

[@generaldisarray]

[@haneyoakie14]

@jcondon1 you also have shown me how to do it. Your work here was very helpful in guiding me to do a rebuild of a 3 HP Briggs flathead. You gave me a visual map of what I needed to do. My engine runs well, and it is because I avoided mistakes I would have made by watching your work. Thank you!

Again, well done! Thanks. It's remarkable how many tight tolerances, spring tensions, jet diameters, etc, etc have to aline! It's, therefore, amazing that initial engineers stuck with it. Just like you! Hurrah!

This has to be the most interesting series of all your generator videos on your channel, not only because of the technical process, but also because of the type and age of the engine.

[@johnsmith7676]

Your big clue here was in the previous video -- the glowing muffler. That always indicates a lean condition or a timing issue. By the way, you do nice work and have good troubleshooting skills. Well done, sir.

[@jcondon1]

Thanks

[@whitesapphire5865]

Interesting..... I had a feeling that valve timing was off, as eluded to in my earlier comment (part 1) but hadn't really considered that someone might actually have been in there and loused it up, but the overheating of the exhaust, and cylinder block, fit in perfectly with what you found. It would also burn the exhaust valve over a period of time. Good work James, on a job well done 👍

[@lesthompson5907]

running sweet now you've fixist it . often never wend wind them i have used I fixed , reliable engines les England

[@davida1hiwaaynet]

So happy you decided to repair this engine. These are the engines which were running the world when I worked on small engines. Some of these engines were configured with the cam to crank timing retarded by one tooth, to optimize the engine's torque curve at the higher end of the RPM range where a 2 pole generator was to be run. This is probably intentional. I really don't think you broke the key in the flywheel removal process. I think it was half-sheared all along and causing the power loss and loud exhaust sound and red-hot muffler you experienced. The resultant high combustion temperature from the retarded ignition timing would explain the scored piston. That piston would have been overheated badly by the late timing. That could easily expand the skirt, reduce the clearance, and disrupt the lubrication film. In my opinion; had you tested the engine with its original piston but with a replaced flywheel key - it would have probably pulled rated power; but would have used a lot of oil and worn prematurely. Regardless, it's great to see it run well at the end!

I read some of the comments and Wow, you got a tough crowd to please! You do excellent work and leave not much to chance... filming is topnotch as well. I'm working on a B&S 5HP with a monarch pump attached... engine was kept outside and stuck solid... piston, rings, and valves all stuck, but are all loose now. This engine has ball bearings and the timing marks threw me for a loop too at first, but both B&S service manuals show the same install sequence as what you did. Just to check though I backed off the bearing and there is no timing mark visible on crank gear, only on the crank counterweight. My engine WILL pump again... great stuff, keep up the good work! 👍

[@markvincenzo4672]

I have a Winco/Dyna 5500 watt 11hp B&S electric start generator, very similar to yours except mine is in like new condition. I bought it new around 1992, was always stored indoors and it worked great for years until it didn't. So I bought a Ridgid/Yamaha 7500 watt generator and then fixed the Winco/Dyna generator. It had a bad diode which after replacing it, the generator worked great again. But it is my backup now as my Ridgid has a function display and a bigger fuel tank. Great videos!

[@robbaillargeon5056]

I believe I have watched pretty much most if not all of your generator rebuilds. This one was one of your best by sticking to it to determine what the actual problem was. The one thing I couldn't figure out was the damage to the piston and cylinder wall when none of the lower end was damaged. I didn't think timing would do that...either it runs or it doesn't, or in this case, much reduced power being timing off by several degrees (one tooth). Excellent work!!

[@dadskrej5226]

The piston/cylinder damage...with the timing off, and the exhaust valve partway open when it should have been closed, possibly canted the piston to one side when the plug fired, scuffing the one side of the piston/cylinder. My idea/theory.

[@woodhonky3890]

Main jet adjustment on all small 4-stroke motors: With engine warmed up, and at speed, open just until misses a little - then turn back in just until it doesn't miss. Running just a hair rich is better than lean. Lean running creates excessive heat in the combustion chamber. Small engine mechanic since 1968.

[@BruceBoschek]

I saw a mechanic in Turkey reassemble a 12 cylinder diesel marine engine using a hose clamp for each ring since the grooves on the pistons were too far apart for the clamp to go over more than one ring at a time. The pistons must have been almost 20 cm (nearly 8") in diameter. It was a painfully slow process, but the mechanic did not look like he was in a hurry. 🙂

[@rancelynch6514]

Very, very interesting and informative video. Very good of you to think about testing and checking the timing. I'll bet it was assembled wrong at factory. You know that the engine has to get hot to seal all the tolerances and then it runs like a champ.

[@captain150]

Really interesting series on this engine. Quite surprised an old school flathead is that sensitive to cam timing. Looks like the cam has about 60 teeth, so 1 tooth would be about 6 degrees. Just 6 degrees and it ends up with 1/3 the power it should, crazy!

[@TheNovaJohn]

Nice catch on the diagnostics, I luv these old engines If I may,, on some engines the carb needs the filter/housing to stop hunting. It depends on the setup but in some cases the longer intake tubes straighten the airflow, condense it down into a laminar flow. In some cases the carb opening can get a poor signal, air doesn't enter in properly and causes issues in the venturi. Now this may not have been the issue here but as you know that intake system is impressive. These are updraft carbs. Not seen in too many engines. Much like the old Ford Flat heads. I wouldn't be surprised if these carbs would run one of those engine rather well!

[@davidwallace785]

Love these videos. Great technical knowhow.

[@ernestbarcella175]

I appreciate and share your enthusiasm with generators of any kind or brand , and your pursue for a perfect result ,,, I have experience with Briggs Straton that the cam loves profile is not of the best geometry ,,even when the correct specified clearance is adjusted if you pay attention when the valve make contact with the seat is very well beyond any reasonable valve timing and that is the reason you see such a low compression I have ground the valves stem to simply satisfy a normal valve timing of some 10 to 15 degrees of overlap right at TDC and only then the intake seals good right after BDC ,, but the clearance is then excessive in the order of 20 25 thousands or more ,, for sure the cam followers do not take full advantage of the acceleration and deceleration ramps ,, they do click , but they run great ... Thank you for the effort in producing these videos ,, EB.

[@Hugo_Overthere]

If you remember this engine had periodic excess turning resistance as the piston traversed the cylinder. The overly tight ring gap which Mr. Condon found, even after cylinder honing, would explain the excess resistance. The new properly-gapped rings solve this problem.

[@filter4now]

Thanks for the info - very informative of the details of an engine problem. I'll tell you a couple of things you may want to try that have helped me. I've rebuilt 2 of these and when they are surging at no load - there's a couple things I found. First - I always replace the governor spring as the constant stretching and tension over the years will inevitably wear it out. Second, the idle jet and main jet have to be absolutely perfect along with the governor spring tension - or else the surging continues at no load. I hate how the exhaust is always pointed at my face when I adjust it - I feel like crap from all the carbon monoxide I sucked in last night even running it outside.

[@jcondon1]

I was just working on a 10hp Tecumseh flat head and was thinking the same thing. No way to adjust the governor spring without putting your face right in the exhaust. Not the best design.

[@garymucher9590]

Two issue that will help you doing such rebuilds. First, if there is no end gap specified, then you use the standard of .004" per inch diameter. Example, a four inch diameter cylinder would have a .016" ring end gap. Secondly, you really need a ring expander, to install rings. You may get away with install rings without any issues until one day, you snap a ring and have to wait for new ones to arrive. There are very very cheap, but well worth the cost. Thumbs Up!

[@jcondon1]

Thanks for the info. This was the first engine I have rebuilt. So did not have the proper tools. Will look into purchasing a ring expander. Most likely will be rebuilding a Briggs 10hp soon.

what caused the piston skirt wear / rocking (?).

[@sikorik9964]

Those old Briggs were really meant to last back then, not so much now.

[@philoso377]

I love to watch the hydraulics in action with positive result. BTW in another channel I saw how a bearing can be removed from a blind well, in absence of a special puller, by hydraulic technique. The idea was to pressurize the junction between bearing and the well bed with hydraulic fluid by feeding through the bore of bearing. Normally this is a dumb idea because water or oil will escape through bearing balls. The trick was to increase viscosity in that fluid - to a consistency of mud and clay - plus inertia. (Same inertia seen in this video aided by an impact driver). In this case, pulverized news paper sock with water was used (although oil and other fine tissue may work too). The mixture was fed through the bore a small batch at a time aided by a firm push of a rod of equal bore size until the paper mud show up at the bore rim. At this time pounding starts, the rod is hammered into the bore full of mud. Water can be seen gushing out between balls but the mud stay in. Continue adding mud after each drive. It was fun to watch it actually worked on something seemingly impossible without the right tool.

[@allrock1238]

One of the challenges with old small engines as well as older automotive engines is that they where designed to run on Leaded Gasoline which was much easier on valve seats due to how that toxic additive coats and lubricates and cushions valve to seat impact ,modern engines that designed to run on unleaded fuel have hardened exhaust valve seats due to unleaded fuels lack of property . Running an engine designed for use with leaded fuel on unleaded requires machining the block (in the case of a L head Brigs and Stratton) or head and pressing in a new hardened valve seat, or using a special purpose lead replacement fuel additive (that does not contain lead) ,Small Generator engines due to how they operate at a relatively high load and speed are more prone to this issue. there are lead free fuel additives for this issue. you will find a lot of old small engines brought back to life that will burn up the exhaust valve seat (if its not hardened) due to this issue.

[@ernestbarcella175]

I have a Tecumseh SnowKing, that has been in service for about 30 years. I doing the same full rebuild, due to excessive ring blow by. It also has an adjustable carb. One of the features of that is you can adjust or optimal performance under various outside temperature conditions. You can also adjust it to optimal performance under load. So when you load it down and it seems to run a bit rougher, just tweek the main jet a little

[@uploadJ]

re: " It also has an adjustable carb. One of the features of that is you can adjust or optimal performance under various outside temperature conditions. " His Briggs in this video works the same way - just 'hit' the carb adjustment screw for optimum performance at the time!

[@sunbeam8866]

Wonderful! All that trial & error to finally discover the timing was messed-up. Like a good mystery - very suspenseful. Now that you put back that spring, maybe you'd like to reinstall the original carb. Or maybe you'd like to never see this generator again! 🙂

[@jp-um2fr]

England. Just found your channel - it's good. I spent several years working on rather large engines and many of them new. It was basically engine testing. One thing I have always wondered about. There seems to be a lot of emphasis on honing marks being necessary to bed the rings in. I never really found evidence of this on engines. Some had quite faint honing but many like Rolls Royce and others had almost a mirror finish. None of the engines with liners showed any at all. I can only assume that with let's just say ' more cost effective' engines it's needed. Sorry to be so late on this but as I wrote I have only just found your channel. Sub'd, etc. of course.

[@jcondon1]

Thanks!

[@v-g-z3689]

Interesting what you say about honing. I have an old german book written between 1959 and 1962 where it says that cylinders must be honed, but if it is done right they do have almost a mirror finish. The guy is talking about that the bore only gets rough and matt over time when something is wrong. He says that the only surface in an engine that needs to be relatively rogh and matt is the part of the piston rings that touches the bore. That is THE ONLY part of an engine that needs breaking in, nothing else. He goes on by saying if a service station or a workshop tells you that an issue on a new or rebuilt engine will disappear because of "breaking in", they want to hide some botch.

Hello James, this is your biggest fan here, I had a couple of questions for you. 1) What do you do with these generators after you rebuild them? 2) How did you get started on rebuilding small engines, is that something you had learned from someone, or at work, or have taken classes? I would be very interested in watching a video on how you got started with engine rebuilds. Also, I have a Husqvarna Straight Shaft Gas String Trimmer that turned off while I was using it during a 95 degree with high humidity outside temperature, and it does not start anymore. I was thinking that I can now take the engine apart (thanks to you and tons of hours of watching your videos) and see if I can figure out what the carb is doing.

[@jcondon1]

I sell them all once they are fixed. I started small with cleaning carburetors and built up my knowledge though KZbin, Google searches and trial and error. The trimmer if nothing else will be a learning experience.

[@donaldelrod9172]

if you have already figured this out, disregard but when i worked in a welding repair shop, these type small generator rotor removal was using a solid rod made from an original mounting bolt with the head cut off about a half inch short and then a slot cut into the end to use a screwdriver to screw it into the end of the crankshaft. then a bold of the proper thread was screwed into the end of the rotor where you tapped the threads, til it applied pressure to the shortened rod and would pop the rotor. hope this makes sense.

[@jcondon1]

Did that recently. Worked well. Of coarse a week later I realized the bolt I cut down was not an extra one.

Remember that a slappy valve is a happy valve.

I commented on the other video that I worked on one nearly identical a few months ago. Fuel supply issues I could never resolve. FYI, the fuel filter was on the carb side of the generator on mine, not the fuel tank side like yours. Not sure if that would make a difference. I kept wondering if the fuel line should be pushed down in the gap between the generator housing and the engine, so that the gas did not have to flow over the generator before reaching the carb. But my experimentation was cut short when the person I was trying to get it run for decided not to use it. Look forward to the next video on this one you mentioned in the comments.

Yes, ideally that fuel line would go down in the gap between the generator housing and the engine. Otherwise there will be fuel left in the tank that cannot get to the carb.

I learn something not obvious to all beginners - the timing meshing of cam gear.
