<VV> CHT Re: valve seats and "Ping"

[shortle]

Hi Mark, Please explain how you adjusted the height up. Did you remove the crankcase cover and tap the blower bearing shaft to reduce the clearance and then reinstall/remeasure? Or did you make a tool to get this proper measurement so you didn't have to repeat? And did this help with engine cooling after changing the heighth?
