The top end was just rebuilt, bored .80 over and has about 5 hours on it, it takes like 5-10 kicks to start it and it wont idle. I have the ngk spark plug(br9eg), carb has been cleaned, tried the idle screw and it doesnt do anything. Any suggestions?

blocked pilot jet? how does it seem with choke?

I cleaned all the jets with an air compressor and it wont start with the choke on

hmm could be a crank seal issue?

Ill go take a look at it, thanks
