Timing a "unknown camed" engine....

sounds like a plan... but I will never drill the trottleplates from my 6319 Thermoquad...they are hard to find...

about the lean condition... the plugs are nice brownish..
and the Carb ist also running a little richer than stock...095 vs 097 primarys.. 1940 vs 1966 rods...

Greetings Juergen
