I think your mechanic friend doesn't know how to clean and adjust carbs or verify the fuel system is functioning, because that's your problem.

We all know that, but picking on his lack of information is more fun.

WTF????...5 months and he can't figure it out? Seriously look elseward.

[arsenic]

Let's be fair. It only took 5 months because the mechanic was training for his event in the Special Olympics.

100 meter kick start

was the mechanic an MMI grad?

[arsenic]

After 25 years, you figure even an MMI grad would learn something.

"IF" the carbs are cleaned and adjusted right, then look towards either blocked fuel flow (petcock, lines, etc) OR gas cap vent is plugged and not allowing the fuel to be drawn out of the tank (like holding your finger over a straw full of liquid...) I am leading towards the vent The fuel flow is just enough to get you up to 35 in either case, but then you wind up starving the engine of fuel , as it can't draw enough fuel and would "fall flat on its face"...

Best of luck with your issue,
