To much compression.help pls

[rednec]

Hey guys

I just upgraded from a 26 cc to a 29cc big bore kit,everything went together well but when I pull the pull start it has way to much compression,

Hmmm, how hard is it to pull it ? If it's so hard the pull that u can't start it u may need to get a thicker shim gasket ...

Well I can pull the car off the ground

Just a question.
Are you sure its the compression - not a stiff pullstart?
Have you tried loosening the plug to see if its easier?
Just a thought.

It is easier when the plug is 3/4 out,and its not the pull start,I checked

Sounds like it is normal to me.
If you pull the spark plug & it pulls over easy, with no drag, I say that would be normal.
Coil binding with the flywheel is another common issue after this upgrade, but should be easily noticed once the spark plug is pulled, and the engine pulled over if so.
