Hello everyone. I recently bought a Homelite 360 because to me it seemed like it was to good of a deal to pass up. When I went to pick it up the guy couldn’t get it started so he knocked off $20, making it only $80 total.
I found that the saw only ran when gas was sprayed down the carb. The reason ended up being the intake boot was brittle and broken in pieces causing a massive air leak. I replaced the boot the other day.
The problem now is that every time I try to start the saw, there is an excessive amount of fuel coming out of the carb. Sometimes I can get the saw to run, but only with choke full off and the throttle fully open, and the saw only barely runs above idle speed. When this happens, there is fuel misting and spraying out of the top of the carb like a little fountain. I have replaced all the carb gaskets and diaphragms, replaced the needle valve, and tried my best to set the needle height adjustment to the right level. The thing about the needle adjustment that I’m not to sure on is that from what I understand, according to the walbro manual for the hdc carburetors, it sounds like you need to set the needle lever height to being level with the carb body with the float gasket on the body using a straight edge. Does that sound right? In other words, the gasket needs to be on the body when the straight edge is being used, and then the needle lever is set to being level with the bottom of the straight edge.
Other than this, I’m not quite sure what I’m missing. The fuel system for this saw seems deceivingly simple, so to me there doesn’t seem like there could be too many things causing this problem. Maybe the internal check valve is somehow damaged, or there is debris inside holding it open?
Let me know if you guys have any advice or similar experiences. Thanks in advance.
