Stihl 045AV Chainsaw Blowing Fuel Thru Carb
I have an 045AV Stihl chainsaw, electronic ignition. When I try to start it, it attempts to hit, but stops immediately. After a number of pulls, fuel can be seen in the carburetor area. If you take the air filter off, you can see fuel on the surface of the carburetor where the air filter attaches.
It is piston port and I am getting 130 PSI compression. I installed a new carburetor kit - gaskets, diaphrams, needle, etc.
I checked the exhaust for obstructions and it is fine. I also removed the flywheel and checked under the rotor. It appears as though the primary coil was not set in correctly (it had obviously been replaced or worked on) and it had worn a place on the inside of the rotor on the inner edge part. I set the stator plate in the middle of the adjusting slots, replaced the spark plug cap and installed a new spark plug. It is getting spark when I pull on the starter.
After all this, it is behaving as though I had done nothing. I am familiar with 2-stroke engines on motorcycles, but not this type of carburetor. Seems to me that with the compression I am reading, whether it starts or not, the fuel should be going into, not back out of, the engine.
Any thoughts, suggestions, etc. would be greatly appreciated.
