Hi, having a bit of a problem with my honda. It is a clean up job right from the start after living in a shed for the past 4 years not going. Started with the usual, strip down clean carby, fuel tank & line, check valve settings, new oil,air filter etc. Got it going and after about 1 minute of running started smoking. Went to take off carby to check clean again noticed oil in front of carby and plastic part where air filter sits, had a look up breather hose, oil. Have gone through other cases such as this checking the ventilation compartment and oil drain hole, all good, took head off to check head gasket, had to change it, put it all back together, still smoking and getting oil through breather hose. Could it be the rings even though there is no movement in piston from side to side, ( had a quick check when i had the head off). Any help appriciated Paul.
