When it does this it will not just idle either. It sounded like an airleak so I replaced the tank, pressure and fuel lines. The carb is cast into the crank. The car runs real strong for that 5 minutes then just dies. There is still good pinch.
I'm thinking bearings.... Am I on the right track?
(1) replace a new glow plug first
(2) check air leak
(3) check needle setting
(4) none of problem of above, you may need new conrod and crankshaft.
Beside, using 16% nitro is better and should have no performance difference even you use 30% since the engine is very small.
Also this engine need modification if you want better perforamnce and not to using 30% nitro.
