Re: Rochester 2G 2bbl carb accelerator pump build

Kind of the same symptoms. That could be a number of different things like
-accelerator pump linkage setting
-Float level
-Timing
283 harmonic balancers have been known to move around so your timing marks may be off unless you have verified tdc. From experience the accelerator pump that comes in the standard carb rebuild kit fits/works but doesn't perform as well as the napa 4037.
I have my timing set advanced 4 degrees at idle, dwell at 30 degrees.
