TC-30 surging

[Ken_W]

Greetings, My TC-30, which is about 4 years old and has 50 hours on it, has developed a severe surge. It won't even run below about half throttle. When I asked the NH dealer about it he said that some TC-29's had this problem but could not find the service bulletin on it. Does anyone have any info or suggestions on this problem? Thanks for any help. Ken

I would drain the fuel system and fill with some known good clean fuel. Also change the fuel filter. Check-replace both air cleaners. I would do this first before I jumped in too deep.

CHANGE THE FUEL FILTER; THEN BLEED THE INJECTORS, THIS SHOULD SOLVE THE PROBLEM UNLESS FUEL IS BAD.
