I see no mention of a leak down test being done, do one before you pull the motor apart to try to diagnose why you have lost compression.
It is normal for a little fuel to be spit out of the back of the carb, that is the reason why a paper air filter should not be fitted directly to the carb throat.
When you pull the pipe off to do the leak test, get a look at the piston/rings up the exhaust port.
To further my education... what is a "Leak Down Test" and how is it accomplished?
I have the pipes off and have visually inspected the rings through the exhaust hole. I have also had the head off and inspected the piston top and cylinder walls. Everything appears in order and no visible scoreing can be seen in the cylinder...
Any advice on top end brand or kit? I'll have it bored the next size up, whatever that is..
