Lowest Price Guarantee
The accelerator pump covers the instant between opening the throttle and the main circuit catching up. When the diaphragm hardens or splits, you get a stumble off idle that no amount of jet changing will fix, because the shot of fuel simply is not being delivered. This is the 30cc gasoline diaphragm for 4150 style carburetors.

- For gasoline use in 4150 style carburetors.
