I wrote down the various steps to check before I go out and purchase one so I thought I'd share it for the next person: 1:16 turn it off 1:39 1) nothing hanging off 1:50 2) check compression by pulling starter 2:20 3) check the fuel and fuel filter 4:00 4) check engine for signs of wear -> take off exhaust -> pull starter to move piston to look more 7:00 damaged piston example with lots of scoring 8:10 5) check for signs of wear in crankshaft bearings -> take off recoil/starter cover -> push up and down on shaft to check for play 10:40 6) check the chain and sprocket area -> does the chain move? 11:30 7) check chain brake -> engage chain brake and move chain manually -> disengage chain brake and move chain again 12:30 8) check carburetor, air filter, and spark plug cap -> does the choke lever move the choke properly? 13:30 9) final visual check -> trigger -> anti vibration mounts -> on off switch

Well done video. (This coming from a retired auto mechanic and handyman.) You added several key issues for 2-strokes which I wouldn't have thought of since I have less experience with them (other than filters and carb cleaning/tuning.) All the info I recognized was spot on and I'd recommend it to everyone interested in purchasing new or used 2-stroke engines. Kudos, Craig.

I was gifted with a 1978 Partner saw. I got it running after tightening things up. This saw was incredibly powerful... and felt blessed with the gift. During a recent episode, it sputtered... ran poorly, then died, not being able to be started again. I checked everything. Carb is clean, free and clear, gaskets good. I pull the plug and am amazed at the amount of spark. When I replace the plug, it still won't start. If I remove the plug and place it near the spark plug hole and give a pull, flames are made, indicating fuel is flowing through the carb. I replace the plug, nothing, not even a hit. I pull then plug again, it's wet with fuel like there's no spark at all. I'm wondering if the wire from the coil disconnects when in place but is fine when the plug is not in. Any suggestions?

@natoyilively93796 жыл бұрын
you also might ask it THEY are willing to do the disassembly and reassembly on the saw. i would be cautious of letting someone do the work, they could easily strip something out. Who's taken the exhaust off? how common is it that an exhaust gasket is currently holding, but gets torn when removed? i've done a little work on motorcycles, and have seen that happen a couple times - before something is taken off, the gasket holds, in the process of removal, the gasket tears and no longer seals. this would be my primary concern (along with stripping out the cylinder with over torquing bolts).

Nice run-through, though I could definitely see a seller not wanting you to start taking a saw apart, potentially breaking something. I had to laugh about the chain brake, too. Don't even buy a saw to use if the chain brake isn't working? 1: if the price is right, it could be worth buying with the expectation of replacing the chain brake. 2: It's "far too dangerous" without the brake? These are relatively recent features. My current saw has one (it works), but I've used saws before that didn't have a chain brake to start with. To me, it's more something to be aware of, and I would never count on the chain brake to save me anyway. You should never try to stop a running saw chain with your face.

If someone came to buy one of my mowers, bikes, chainsaws or anything and wanted to take it apart I'd just tell them to buy one from someone else lol. And I have, check it out, check the air filter but taking bits off is just cheeky. Buying something used carries a risk and that's that. If it runs well and works as it should that's enough.

Bullshit. If the seller claims they know a lot about this stuff, ask him to show you “where the parts like piston, flywheel etc” are located. If the seller says they don’t know much about the thing then educate Them about what’s where and I’m good shape. I live in the county of California that had something like 90% voting for trump so i come from one of those Places in America where people get shot by farmers and lumberjacks and shit, and decent folks are very polite. If someone doesn’t want to let me test drive a car and look under the hood then I would tell them to get fucked and spend my money elsewhere. Maybe if you just started pulling shit off the saw without asking, but nobody should refuse you that simple request.

I inherited a Husqvarna 55 from my grandfather. I started to clean it up last weekend and found it to be in great shape overall, except the area inside the chainbrake cover was scorched. The brake would not disengage. After taking the handle apart I saw there was a spring that had broken. I went ahead and ordered a used brake assembly I found on ebay due to the overall burn damage around the brake ring. Cost me $40. Now I have a good brake and the old one full of good parts should I ever need them. To replace the spring would have cost me 5 or 6 bucks, but the cover was so burnt up I didn't want to chance it causing more problems down the road. Only thing I can figure is that he ran it without chain oil at some point or let the area get too clogged with sawdust. Any ideas what else could have caused this area to burn?
@TheRepairSpecialist7 жыл бұрын
Dr. CisScum Shitlord III, Esq. you are correct with the suggestions you have made so far and something I would add to them is that sometimes the chain brake can be binding to the clutch enough to cause the heat damage. This can be caused by distortion of the chain brake cover or incorrect cover etc. Now that you have fitted your replacement part it may be worth taking a look through the gap underneath (between the saw body and the cover) to see if you notice any areas of excessive contact. Just make sure your clutch turns freely (you can carefully reach in with your finger to mover this slightly when not in use). Just ensure that there is no evidence of contact between the clutch and the brake band. Even if there is slight scrubbing there it can create quite a lot of heat. This would be my main suggestion to you as a process of elimination before going any further. I hope that helps a little Doc. Thanks

I'll do that and keep an eye on it as I use it. I actually enjoy taking chainsaws apart and putting them back together nice and clean. I should start a business doing repairs for some extra cash. Thanks for the advice. Now if you could just help me find that little E clip that popped off the pin from the handle when I took it apart to get that broken spring out of there. I guess I should invest in a good magnet.

Hi Craig. Iwonder if you could help me. recently I have been asked to look at friends strimmers and bush trimmer,but mostly to no success. They all had a Walbro type carb but the low fuel adjustment needle on all had been bonded in the center of the throttle lever aperture. Out of the three, I could only repair one. The rest I had no success getting the flexy sealer out, to reveal the low adjusting jet. What I have found is they use different sealant to cover the Low fuel jet. Do you know where I can purchase a new needle to replace the two That I broke , tying to de- plug them, Please? I would much prefer to repair them, rather than replace the whole carb. Any info/ help you can through my way, will be deeply appreciated. Many Thanks, Leon. :-)
@TheRepairSpecialist Жыл бұрын
Hi Leon . Sorry to hear you have been having problems, I too have had similar issues like this in the past. If you take a look on the side of the carburetor, thee should be be some code numbers ( there’s should be present especially with it being a Walbro carb). If you take these numbers an Google search for parts, or look on Amazon, then hopefully you might find a service kit that may have them present within. If not then another successful outcome I have had in the past is to look for the same type of used carb on eBay, which may well have the parts you need still in tack. Even if the used carb is not of usable quality, the parts are usually re-usable. That’s all I can suggest really but I hope you success here, otherwise you may have to find a total replacement unfortunately. Sorry to be the bearer of bad news. Thank you and I wish you all success here. Craig

What I've been doing is ask the seller whether they're fine having me "dismantle" their prop to check [insert something specific the seller would typically agree is worth checking], or if not, whether they would be willing to go for it. Either way if they disagree, I'm out. Not buying a black box!

Then you would expect to get a low offer cause the educated buyer would have to assume you are hiding something or you truly have no mechanical abilities or understanding of what you have. Then an offer would be made to assume all is bad! I have 30 year old saws that you can take the exhaust off of with no worries. And if you think taking a bolt out or nut off is bad your equipment is more then likely trash to be.
