Default Re: Trouble shooting the bicycle engine that won't start

Thank you. Also, I am having some starting issues. Do you know what the head bolts should be torqued at? What kind of compression should the cylinder have? I am thinking I have reduced compression.

There is plenty of fuel coming from the carberuator when the plug is in and ignition when the plug is out of the cylinder head. When I place my thumb over the spark plug hole and spin the engine there is some compression but not a whole lot.

Tonight afterwork I am going to check to see if the keyway is broken or wobbled out. These engines are basic so it should be easy to troubleshoot.
