carb bogs when wide open

<< < (2/2)

Cliff Ruggles:
We're still backlogged well into next year.  That carb used a rear pull-off, but it is not needed as long as the front pull-off is working correctly.

The 1975 models are the most difficult of the q-jets, as they have an "odd" APT system.  Most likely in your case you just need to install smaller secondary metering rods. 

A new secondary plastic cam and spring would be a good idea.

A bad accl pump will also cause stumble/hesitation/bog when you get into the secondaries.  I would install one of our kits to get the carb up to par for modern fuel, and improve performance in all areas.....Cliff
