Just changed tips on truck with 80 hp 105 ft lbs tc tips. Allso set lash on
valves.Truck runs great .The only thing is sometimes at startup the very
instant it fires I hear a knock knock blows puff of smoke from tailpipe
then all ok no smoke at any time. Seems worse on hot day after setting
for say 15 min.Only happens sometimes.Any ideas on what is causing this?
