couple of minutes 3 or 4 probably to give the motor a chance to cool. And about an hour in between tanks again to let it cool down, Important thing is Take your time, you don't want to get hurt or ruin your investment. On about my 7th tank I lean the low speed needle about 1/8 of turn.
so its like, full tank....run the engine at max rpms for 5-6 seconds...then close the needle one turn....leave it that way....then after 4 minutes again max rpms, etc. Thanks a lor for your time and help. After a broke crankcase i just want to double check everything...i was lucky that O.S. replce it under warranty.
