041 No Start

[a. palmer jr.]

I bought this Stihl 041 last week hoping I could get it to run and so far I haven't. It has over 150 compression, gobs of spark but won't hit a lick even when you put fuel directly in the carb or spark plug hole. All it seems to do is wet the plug and doesn't even pop. I cleaned the carb today and checked the fuel lines and impulse line which were all okay. Any ideas?

Pull the flywheel and check the key.

Crank seals

Fuel is getting to the top of the cylinder, just not firing. I'm using the same fuel I've used in other saws so the fuel is good. I've considered the flywheel key might be sheared but haven't pulled it off yet. Thought I'd "beg for a manual" first so I won't screw anything up.

Looks like that's next on my list. Usually when I check the flywheel they're always in the correct place so I waited until about last to check it.

Ya listen to Brad, they were prone to that. Same thing happened to mine.

Tighten down your cylinder bolts.

Try a different spark plug if you haven't already.

Maybe the 041 has a heavy flywheel which would make it easier to shear the key. I'll tear into it some more tomorrow if I have time. I wonder if I can pull that sucker without the proper tool. I think Stihl makes a puller for these.

If that's the problem, once you take the nut off, the flywheel will fall off.

If I remember correctly the flywheel on my 041 super came off with just a tap or two.

I hadn't thought of that..If there's room I could always hammer it off like on the Poulans. Usually just a tap or two and it's off.

Check the gaskets under the carb heat shield.They go bad when the carb is loose.

Good idea. Those woodruff keys are aluminum and very soft. Easy to break as I know all too well.

Iv had the same problems with a remington sl10 (in john deer colors) getting spark, wet plug, 125lbs of compression, and yes I checked the flywheel key. But nothing?

Do all of the above :msp_rolleyes:

Another thing to check, which I already checked on mine is the input lever on the carb. If it's too high it will flood the engine. Unfortunately mine was in good shape. I cleaned the carb anyway put it back together and still the same flooding. I'm going out now to jerk the flywheel and see if it has a key in there.

Well, despite what I might have thought, this flywheel isn't gonna come off without a puller which I just ordered. I'll set this unit aside for several days while I wait for the new puller to come in. Too bad I couldn't use my old Suzuki puller to get it off with but the Suzuki puller is too big. I imagine this means the key is probably okay also.

I pulled the flywheel this morning. The key was just fine. I'm reluctant to check the seals at this time because I have a suspicion that it's still a timing issue. Fuel does make it to the upper cylinder, just doesn't fire it. I used to have an old truck that had good compression, fuel and spark but wouldn't run...turned out to be an open condenser. If it was a shorted condenser you'd have no fire at all, but I was informed that an open condenser would still give you spark but it would be at the wrong time, so I guess I'll check the condenser next or just replace the points with one of those "eliminator chips."

I been down that road before, We had a yamaha Pulled and pulled on it took the spark plug out Big Spark still nothing changed the spark plug started right up.
