this has been a pain, it doesn't want to come down to idle and sit there, it seems like a passage in blocked in the low speed side of the carb but I think surely out of 3 carburetors there would be some difference.

My Craftsman lawn tractor was doing the same thing. It was a good time to do a preventive maintenance. I suspected a fuel issue and basically what he did except I did not swap carburetors. But I did remove it and basically cleaned it. I never thought opening the carburetor up but just give it a good bath with brake fluid. Considering the way it was running after starting the mower, I just knew it was a fuel issue….somewhere between the gas tank and the carburetor. I read all comments on this thread and ran across 1 comment that I never thought of and made perfectly good sense. The comment was “the gas cap”. The next morning I unscrewed the gas cap but left it over the the tank opening. I turned the starter and “BOOM “ cranked beautifully, it did surge a little bit, but after it ran for a solid hour, it ran and sounded like a new engine. If you ever suspect fuel issues, don’t forget the gas cap is part of it also.

It was the low speed jet. Those are Nikki carburetors. They are only about .015 thousands of an inch from the factory. Because of EPA regulations. There are no adjustments on those particular carburetors. The aftermarkets state they are good for 10 horsepower to 18 horsepower. Once you get close to around 16 horsepower and above they are not efficient no matter what they say. The jet is located inside above the float assembly. It needs drilled out using micro drill bits. The reason they work great when it was new is because the ethanol hasn't had a chance to gum it up yet. Once it gets older it starts to do this surging. Generally drilling it out to about .024 thousands of an inch gets the job done. You really want to try to take it one step at a time. That's about a .6 mm drill bit. Very small. NOT 6MM--- .6MM there are other videos showing where this is located and how to step it

What fixed it for me was replacing the spring that is attached to the governor. The spring is located behind that small plate that the throttle cable is attached to. At the end of the throttle cable you can see the white piece of plastic that slides back and forth as you move the throttle cable. It is on the other side of that plate. About 3 inches above and to the right of the oil filter. My spring was a little mangled and a new one fixed it.

My John Deere with the Briggs engine kept doing same thing. I had changed a lot of things then I watched a video that said the electronic round thing on carb bowl was either sticking open or shut, that I could put an inline shutoff valve in the gas line around the filter to full pump but to cut the end of that round thing that controls the gas into the carb. bowl. I did that this morning and my mower started right up and didn't die out but did surg until I adjusted the gas screw and lowered the chokd idle control handle to halfway point. It sat and ran good but a little fast for about 12 mins. so I got on it took it about 50ft. tried to engage the deck, the engine stopped, flooded gas out of bowl and now won't start again. I covered it up and walked away. This mower only as about 245hrs. on it. It is agrevation but I enjoy just tinkering with them. I have a stack of riders that all have some issues and a stack of self and non pullers mostly the kind all 4 wheels pull.

I can tell you what I went through. End of season last year Engine got heavy to turn. It has 16HP and one spark plug. I removed plug and air filter. Gas was in both places. Oil level was high. I knew that the Walbro carb had a needle valve leak. Put on a Chinese carb and could not get it to work properly, also put a gas shut off valve. I lapped Walbro seat using a drill with wooden cue tip some polish and it worked. I finished the season. This year 1st cut I lost power and started surging. Well I found that the shut off valve was plugged from stuff in gas tube. So I cleaned the tube and put another shut off (I bought 2). I finished the grass and it was a little erratic running (I had reinstalled the Chinese carb) but was able to finish with no loss of power. I imagine that dirt from gas tubes affected both carbs. So I will clean bot carbs. I would diagnose these surging problems as such: 1- Loss of fuel 2- Dirty Carb 3- Intake vacuum leak 4- Bad Ignition coil (intermitent) replace 5- Sheared fly wheel key

@@splash5974 backfiring 'most of the time' is the retainer pin on the flywheel shaft has sheered and you need to pull the flywheel and put a new pin. The magnet pad on the flywheel passes the coil as it spins and sends the spark. When the flywheel is twisted off center because of the broken key pin, the timing is moved and it is firing at the wrong time. When it is NOT the flywheel.. you are likely screwed. Replace the coil. Make sure you do not have weak intermittent spark. Some engines have an anti-backfire feature built into the air cleaner cover. If you have that.. it can get broken wires or otherwise malfunction.

Sometimes the fuel shut off solenoid goes bad or you don't have electricity to it. (That's the part sticking out of the bottom of the fuel bowl.) It is supposed to close when the key is off to stop backfiring caused by the more volatile ethanol gas. When the key is on, it opens up allowing full flow. There is a spring I think that is activated by the solenoid which moves a stem in the center of it. This is what does the plugging. If the solenoid goes bad, or if there is no electricity to it, then this center stem can slide up and down, blocking and then clearing the main jet. I just cut the plug part off with a dremel. It worked fine after that. Of course, if you live in an area where they check emissions, you'd better not do that.

Did you try a new small Red or White fuel filter like the one you replaced that was designed to be used on engines with the gravity feed system? The large clear fuel filter is made for engines with a fuel pump & it is most likely too big. Maybe shorten the fuel line too so gas isn't trying to go up hill with the gravity feed system.

The fuel lines drooping. I'm sure you probably figured this thing out by now and I'm wasting my time but since it's gravity fed if you're short not fuel line up so it's more straight from the tank to the carburetor it will feed the gas more steadily. Also I seen another video where the guy said since his fuel line was drooping it was in the past of where the hot air is meant to dissipate and it was evaporating the fuel before I could get to the carburetor. But even in that video I think it was because the fuel line was drooping so much it wasn't pouring as steadily as it needs to straight from a tank to the carb.

in this case the tank is lower than the carburetor so I had to put a pump on it, so the drooping doesn't matter, thanks for the comment.

actually, I never did figure out what it was,, I just started using it and it got better, the only thing I can think of was there must have been some dirt in there that finely came out,, usually that surging is a problem in the low side that is plugged and when the engine tries to come down to idle, nothing is there so the governor pulls the carburetor back up to the high speed section , and so on and so on. good luck with your engine.

@@MissouriOldTimer After 3 different carbs without solving the problem I think you can rule out the carb itself. Gotta be linkage spring or fuel delivery. Ethanol gas can rot the inside of the fuel line causing partial blockage. I've seen that before. Bought a beautiful Craftsman tractor once for $25 because it wouldn't run right. Sears put a new fuel shutoff and 2 new carbs then gave up. It would run strong for 10 minutes and quit. As soon as it quit I looked at the fuel filter and it was dry. It would then very slowly fill. Replaced the fuel line and filter making it shorter, ( there was a big dip in the line), been running great ever since. (3 or 4 years now. )

Bad coils could cause performance issues, and no one really ever thinks of that. It may have enough spark to start the engine, but there are videos that show how degrading coils affected the rpm's of an engine. If yours started to work again, good, but it could be getting ready to fail. I'd check the Ohms on your coils with a multimeter. Again, there are videos about that.

The answer is more simple that you realize. The answer is those engines surge if the air cleaner box is not installed. The air cleaner box with the air filter, acts as a sort of air flow limiter and this suction or limiting of air flow to the inlet of the carb is required to keep the engine from revving up too high and causing the governor to go wild as it tries to compensate for an engine that wont sit in the rpm range its set for. Put the air box on and I bet it will run fine.

Vernon, if you didn't get it yet, there's some things, you may or may not know that might steer you into fixing it. First of all, (as you may know) these modern engines are all made to qualify for EPA regulations using what the factory calls, "Lean Drop Idle," wherein the jet, whether it's adjustable or not, is set to where the unit will just survive running on the idle circuit. ANY loss-variation of fuel on the negative, or any gain of air on the intake, and you risk it doing that loping idle. First, look to see if that used one, or either of the Nikki's has an adjustable fuel-idle circuit or an air mixture screw, (sometimes hiding pretty good around the left stud hole). I'd use whichever carb has adjustable jets of any kind. If that used one doesn't have adjustable, you definitely want the new Nikki on there. Then make sure, the air intake to air filter assembly is totally sealed on assembling and you have a good air cleaner installed. That will assure, everything is just the way the jets are ported to run properly. If none of that helps, before you do any changes to the port, you should do these things: 1) Switch to ZERO-corn fuel, run it for a half hour or so and see how it does. 2) Check and adjust the valves. I believe that one is 2-3 thousandths, if the spec is 3-5, go 2-4, etc., I always go to 1.5-2 on worn engines. Make sure that troublesome valve cover - to intake tube is not cracked or leaking anywhere. Finally, look close at all those carbs. Hopefully one of them has a welch plug somewhere on the left side that can be removed. On rare occasions, I've used a torch tip cleaner and (ever so slightly) reamed the tiny hole going into the back of the carb throat just on the other side of the throttle plate. From the start I'd say just clean those tiny holes out, but you have a new carb there, and that shouldn't be dirty? Either way, it's about the only way to correct that. UNLESS, someone's really messed with it and changed your low-side governor spring? Pretty doubtful, but it's possible? Good luck. . . FYI, not messing with you Vernon, been working on these for 50 years, this is the same step by step we'd go through on any customers rig. Very doubtful there's anything wrong with your original carb, it's a very good quality, tough carb. Good luck.
@MissouriOldTimer6 жыл бұрын
thanks, those are some good suggestions, surely some of that will fix it.
@jasperwilliams31546 жыл бұрын
well, the last ditch fix of drilling the jet orifice out will (if done right) will always work, but it generally means one of the others was overlooked, or, the valves are falling out of adjustment. They are very particular, you have to hold that allen wrench as tight as possible while locking it down, just a smidgen of a movement at that moment can throw it 3 or more thousandths off. After giving this some thought Vernon, since you've essentially proven it's not the carb, I'd put the original back on and troubleshoot from there. Sure hope you get this, interesting to find out what you finally did Sometimes they're so particular, just cleaning the primary jet tube out, (especially all those microscopic holes that run up and down it's shaft) will often solve it. Those things need every infinitesimal bit of room for fuel flow that is given them when manufactured, they allowed practically zero room for even a thin coat of varnish to build up on them before problems ensue. Good luck!

Could it be the governor spring? Mine ran well with the old carb but the carb leaked. I got a new one. Now it backfires back out of the air intake. Looks like most is shooting into the carb from the breather. I was thinking too much air, but my friend messed with the governor spring and the little screw on the linkage. Could that be the problem? I tried adjusting it all different ways. The engine only doesn't backfire when I have the idle turned way up. Thanks.

After reading all the comments (my old 11HP Briggs Stratton Murray tractor had the loss of power backfire puffing situation) first thing was replace the carb, next pull the flywheel, then adjust the valves, replaced the fuel line and filter, nothing has really worked, I also tinkered with the governor a bit and I think that may be an issue because for a while I could actually run the mower and cut grass. The spring on the governor and the linkage spring are two different items. I need to experiment there. Also the fuel filter does seem to be the large clear style and is odd the way it fills and bubbles back so maybe I need to take a look at that possibly bypassing it to make sure that is not causing an issue.

@jasperwilliams31546 жыл бұрын
I was hoping he'd done that first, as you apparently know, all these "lean drop idle' engines have to have the post-carb air intake completely sealed. When they first came out with these they proved how critical it was and how bad some after market air filters were by putting a couple of them in a new engine in the Briggs update seminars, and it did the infamous loping that Vernon experiencing, and that we used to see a dozen a week of in our shop. They must have changed the valve porting in the newest models as this is no longer an issue.
