Answer
hello gary,

it sound like to me you may have bent a valve causing the pressure to stay inside the engine head instead of blowing it out the exhaust head or make sure you are on top dead center with yur timing marks this can also cause the kickstarter to kick back during the time you try to kick it over let me know if you need more help im here ok , i will check with one of my techs tommorrow on this problem ok.i will follow up with you tommorrow night ok. sincerely,

mitch
