Sure could be something arcing over. Check spark plug leads for cracks,etc (ie, run at night and look).<br />Coils will have cracks in the insulation if they're bad. Only way to test is with a HV leak tester, which is not a common test instrument.<br /><br />When it's hesitating, do you have enough time to squirt some premix down the carb's throat to see if it picks up? Or bump the choke?

They're pretty easy to fix if they are bad. Just line them up nice and even with the bosses they sit on.<br />Cheap too. $17 each at Iboats or NAPA. Might want to replace the spark plug wire too while it's off.<br />Use metal core stuff, eh. No automotive wire.
