My turn with the 5.8;
this is my favorite engine, I absolutely worship its power to price ratio.......


After using this size and brand for a few years now, I have a new problem, engine will not run at any throttle setting past 30%.

Starts fine, with a flip after choking, idles fine at a steady low pace, will advance on power fine to 30% then dies. No burps, no slugs, just stops running as if the fuel is shut off.

I had the ignition unit replaced, and swapped up to a 1400mah 4.8 volt battery. Any input would be appreciated, as I need this motor to drive my P-40 in 4 days!

Thanks in advance,
Ray
