OS 46LA engine stops when throttle is fully open
by Vivek
(INDIA)
I have OS 46LA engine. Fuel mixing : 75% methanol,20% oil, 5% Nitro.
I have new OS 46LA engine and I need to break in and set the high speed needle at a good position.
But when I try to start the engine, initially engine starts at low RPM with 1 and 1/2 high speed needle valve opened and 1/3 throttle opened.
Then I gradually start opening the throttle. Engine RPM is increases up to 85% throttle open but after that around 90-95% throttle open the engine stops.
So I never get a chance to start the engine and run with fully open throttle and then set the high speed needle valve. Please provide me some of your experience to solve my problem,
Yet I have not burn a single tank of fuel yet.
I really appreciate your help,
Thanks,
Vivek
