I cleaned all the passages with WD 40 and blew out with compressed air. Detected air flow through passages. I have not checked cylinder compression.
I engine sounds good when it running.
No, there is a single fuel line to the carburetor only.
What should the cylinder compression be if I can get my a gauge into the plug hole?
Then it has a pulse passage that may be blocked. Be sure and check. Look for a small hole underneath the carburetor that supplies a pulse to operate the fuel pump.
A two-cycle should have at least 120 psi.
