carb. problem on hp 61

Postby triumphman » Sat Feb 25, 2012 10:51 pm

I was wondering if anyone can tell me how the accelerator pump piston goes in, cup out or crown out?
I also am having a problem with my high end getting rich enough. I have the tank pressurized but every time I point the nose of the plane up it leans out.

Crown out.

It should be fine with muffler pressure.
