im no good with diagnostics, may have to go to mechanic for that.... it blows black smoke under hard acceleration, idles a bit rough and smells very fuelly
will do thankyouAlso its likely that the rings are fouled with carbon deposits because of the over fueling and this would be compounding the problem. Once u have sorted the issue give the engine a good internal clean. Carby cleaner down the spark plug hole let it sit overnight and then drain the oil. Follow that up with an engine flush using cheap new mineral oil and then drain the oil again and then put in good quality synthetic oil. This should clean the engine up considerably.
Opcom is cheap i paid mine only 40 AUD delivered - its a clone but it works. Not hard to use.
