Hi,
tried the seafoam but everything still the same. The throttle slowly drops from 3000 revs only after I've wound the idle screw in to produce an idle. If I wind it back out so there is no idle then there is no delay in the rev counter drop, it also seems to smoke more when I wind the idle screw in.
Do you think I may be looking at a head gasket or something worse????

Thanks,

Poolie
