I'm getting ready to remove and rebuild a Holley Model 885jjg carb, list # 1062 from a 56 GMC 630. It has sat for decades. I would prefer to eliminate the governor, but my brief research shows that the gov is an integral part of the operation - that in fact it holds the butterfly open at rest; and when the engine is started the governing function brings it shut. I'd like to keep this carb, but not sure what I will think after taking it apart and trying to find parts for it - especially parts to repair the governor. Do any of you have experience with this particular carb? It apparently was used on 55-58 503's.
