Karla, Here are the results. After using compressed air in carb and plug I did not get any results. No hiccup, burp, etc. Primer bulb stays full of fuel. I did the test with the pump and it held pressure a 10 psi. There was no pressure drop at all when pulling on the starter. Should I check impulse hose? Do you have a diagram, or any tips? Thanks
Karla, I did the spark test as you recommended and I get spark. Yes, I have an air compressor. I also turned saw on it's side, back, etc. and no fuel leak. What next?
Eugene, I took the muffler off and checked cylinder that way. Looked very clean and smooth, and the ring was slightly potruding. I have watched a number of engine rebuilds on you-tube and the cylinder, and ring looked similar to those after a rebuild.
Well, I got the saw back, but I am still not sure compression was done correctly. Let's assume that I do in fact have compression. Reason I say that is I checked piston and ring and both look fine. No scratches, no carbon build up, nothing. It looks like you would expect from a saw that only has 10 hours use. So to start over, I have compression, spark, and new fuel. Pouring fuel or adding starter fluid to the carb did nothing so I doubt this is a fuel issue even though that is what the local shop thinks. He says get a new saw but I know this can be fixed for a lot less. Any thoughts on where to go from here?
Thanks for the replays. Shop told me compression tested at 60psi, and he thought that was enough to at least attempt to turnover. How do you remove the muffler and what exactly am I lookin for?
