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