I have an 011 that I picked up. Havent had the time to mess with it. But when I got it it fired up. Ran writes and had a wanky idle and would idle high. So I got it out this week to mess with it. Got it fired and ran a bit still high idle and carb would not really respond. Then died and I could not restart. Nothing , figured the carb diaphragm or something or a jet finally had it. Kept yanking on it no fire. Went to youll the plug and the cylinder was wobbling and loose! So I pulled it down to expose it. I did not pull the jug off I just tightened the two bolts down tight. Before they were even snug I could feel compression coming g back. To get to one bolt I had to pull that weird muffler on these horizontal saws. Piston looked good as did the cyl walls through the plug hole. Still won't fire. So I put some fuel into the carb and still nothing. Dried plug and pulled engine over to expel excess fuel reinstalles and a tiny bit more fuel and nothing . All I have to test spark is one of those cheap inline bulb testers. It lit up so its getting some amount of fire. I tested compression. It was low for a saw only like 115# or so. That seems weird to me looking at how good jug n slug look. As well as the saw doesnt look to have many hours on it and was used around a house for small trees and stuff I assume. I would think even at that love compression it would fire. Any ideas? I am about to swap the plug from a known running saw to see if that makes a difference. I have a carb kit on order but if it won't fire from fuel directly into it what good would that do?
At that compression even with a leak wouldnt you expect it to at least fire even if it idles way high and is all over the place.
I missed a bit of your post. Those saws flood real easy. Is it possible that it has a bit of fuel in the case? Yeah, even at 115psi it should fire.........but it won't run well there. Does it have a black plastic piece between the jug and the case?
Yea some sort of gasket. I didnt pull the jug so I am not sure if it was plastic fiber or what. This came from an old guy estate. The saw looks low hour.clutch looks very clean and drive sprocket has very wear as well. Bar looks new but I assumed it was a replacement.. maybe not? I dont think anybody has molested this saw.
There are two totally different versions of that saw. One has a black plastic spacer that is about 1/4" thick between the jug and case.......the other just has a gasket. The one with the spacer is tough to keep sealed up. There's a piece under the carb that warps......
This one looks thick like plastic. I havent pulled the carb yet. This one has a round cylinder and a tiny exhaust outlet. My other 011 has a square cylinder and an exhaust outlet about 3x this size as did one I just flipped.
I had one I fixed and mine acted similar , It was the harness going to the coil . around the flywheel,
Wouldnt that mean I had no spark then? I have a spark...I dont know how strong a spark it is? I assume a weak spark won't fire bit if it lights an incandessant bulb that I can see in the shade of my shed would that me strong enough to fire....maybe , maybe not??? I will check the connections.
Clem, Even your "dummy" light can be used as a Cheapo spark indicator. Check the spark when the coil wire is connected directly to the cyl fin bypassing the plug. That should be the brightest strongest "light". Then compare the "brightness" of the light when you connect the dummy light through the plug. If there is a huge difference try with another known plug. At that point you have a weak coil or a bad wire. Re gap the coil/ flywheel space and confirm the key has not sheared. Check back after that. Me I'd be looking for where that leak is for 115 psi. Rings, base gasket cracked cyl...
