alvin123 Posted May 31, 2011 Report Share Posted May 31, 2011 Hi when I take the engine from idle very gently it splutters like mad, push it a little more it clears and edge out fine. I have cleaned carb, changed plug, a ngk bpr5es. Also I have played with idle and mixture screw. Filter is clean and exhaust repacked. Any ideas on base settings, needle positions or indeed ste jet sizes? Thanks in advance. Alan. Quote Link to comment Share on other sites More sharing options...

telecat Posted June 1, 2011 Report Share Posted June 1, 2011 If fiddling with the carb does not work check the base gasket. Quote Link to comment Share on other sites More sharing options...
charliechitlins Posted June 1, 2011 Report Share Posted June 1, 2011 Thanks, which is the pilot circuit? It's the small jet next to the main jet. Best cleaned with carb cleaner and compressed air. If you must stick something in it, make sure it's neither pointier nor harder than a Polish sausage. Quote Link to comment Share on other sites More sharing options...
alvin123 Posted June 1, 2011 Author Report Share Posted June 1, 2011 Thanks for your advice. I'll strip the carve and give it a go. Quote Link to comment Share on other sites More sharing options...
