The new jets are wrong. The new ones are the Vm22/210 type. The ones that I pulled out are proper 90/96. I guess I'll try 45's in the proper jet and see how that helps me. I'm still a bit confused, because my plugs show signs of richness, but I believe it was you, who said that the cracking and popping from my exhaust is a sign of leanness. Could this simply be a matter of tuning and still the wrong pilot jet?
