So I'm reading the intructions for this kit and I read this short sentence saying that i should lap the head valve and check for tightness. I've used lapping compound to final fit gears onto shafts before. Do you think that's what they want me to do? I'm talking about the decompression valve for a vespa motor. hmm. Your thoughts?
