<font face="Helv" size="2"><font face="Helv" size="2"><p dir="ltr">I have recently bought my first nitro car (schumacher rascal 2) after a few years messing with battery cars.</p><p dir="ltr">I have broken the engine in following a online guide from schumacher. Now the engine runs reasonbly well, but something is wrong I feel.</p><p dir="ltr">When I start the engine from cold, it takes a while to run properly I think, and once it is warmed up it seems ok. On acceleration it seems to smoke a lot, but does accelerate quickly but then at higher revs it really does fly.</p><p dir="ltr">After a few fast runs, when i try stop the car, the revs are really high, and I cannot keep the car still. But when I let the car cool, start up again the revs are fine again.</p><p dir="ltr">Only when the car is up to temp, it revs too much at idle.</p><p dir="ltr">My gut feeling is that the high speed needle is too lean and the low speed is too rich?? But being a beginner I would rather some pro advice!</p><p dir="ltr">Thanks for your help.</p></font></font>
