i own an old NSR12S5 engine with about a gallon run through it. the engine runs good, idles well and temp is good (230-240F).
my concern is that there would be times were coming from a curve going mid throttle and going to a straight, the engine suddenly dies when i squeez full throttle. what do you guys think is the problem here. definitely not the glow plug as i've change to new plugs and same problem... using tornado 25% fuel.

also, will any nova .12 conrod fit to this engine? TIA...
