lemur Posted June 28 Report Share Posted June 28 Tell of too much oil in your pre mix is how badly the exhaust plugs up with unburnt oil residue, naturally fuel rich condition intake also relates to oil rich. Your air cleaner filter needs to be clean and oiled correctly or that will starve the engine of air and lead to rich operation and poor performance, the reed valves need to seat perfect or scavenging pressure will force fuel and compression backwards through the intake so make sure the reeds seat perfect. Compression test is never a bad idea for diagnosis and future reference if you have the equipment. 👍 Quote Link to comment Share on other sites More sharing options...
