first check that slide is going up, then look for air leaks & gasket leaks

Thanks man! How do you check for air leaks?

I'm thinking fuel starvation. check for kinked fuel lines and clogged fuel filters

plane the head and cylinder to prevent common head leaks which rob power

for air leaks it is easy to use a spray bottle to spray water around the intake area while engine is idling - if the water hits a leak, the idle speed will slow down

checking for gasket leaks is done by looking closely for any sign of oil seepage around the gaskets

What do you mean plane the head and the cylinder?

don't worry about it - one big reason heads leak is because someone planed it & lost the raised compression ring molded into it that is needed to properly seal it
