No compression

  This topic is about my 1965 Vespa VBB Standard 150

I recently rebuilt the engine on my VBB. Now I have no compression. Any suggestions other than the obvious like a broken ring?

Hello,
Check firstly the obvious things, like if spark plug hole thread is stripped, did you use good gaskets and jointing paste in the re-build, Are your cylinder head nuts torqued to the correct settings using a torque wrench. If no joy you may have to spit the crankcase.confused smiley
