miniwing2 Posted May 31, 2013 Share Posted May 31, 2013 dose anyone no why the RPM increses after it,s tickover has been set .in this case it,s on a mikuni vm 26 slide type carb .after about 20 seconds the RPM goes from 1500 to well into midrange around 2800 rpm then slowley dies back to around 1000 rpm then after about twenty seconds eventualy dies .it never returns back to tickover.this is what i have tried .lowering needle 1 notch .lowering float level .and the usual trial and error approach .i seem to think that with the long fuel track and the and the rubber adapter and the fact that it shakes like a flipping bitch it could be the cause,heads together boy,s please.can,t do alot at the moment until the plastercast comes off my toes Quote Link to comment Share on other sites More sharing options...
enzo200500 Posted May 31, 2013 Share Posted May 31, 2013 Could be air leak on intake side, crank seals worn, allowing air in. Shaking of the float bowl carbs causes the fuel to aerate (foam)in the bowl and cause erratic running. Usually spluttering, missing etc. My money is on air leak somewhere.....

miniwing2 Posted May 31, 2013 Author Share Posted May 31, 2013 Guy,s i am in total denial about any crank case leaks and you will probably get the impresion i am making excuses why i shouldn,t take it apart ,although you make a good point.So how do people get around this problem thoses that have fitted mikuni ,bing E.C.T .the level of vibration is not right by any means although mountings are good ,and as for air leak around the carb the nitral adapter is new and bolts are tight ,here we go again,anyone no where there is a walbro carb and adapter going Quote Link to comment Share on other sites More sharing options...
