woodrow Posted June 16, 2019 Report Posted June 16, 2019 I have to rebuild one of my carbs as the acc pump is not creating vacuum causing absolutely pathetic throttle response and the carb is generally in need of an overhaul. Where is the best place in everyones experience to buy a quality kit? and when buying what material should i be looking for the acc pump to be made out of? Quote
Dodgeb4ya Posted June 16, 2019 Report Posted June 16, 2019 Daytona parts in Florida... was impressed with their parts, knowledge and service. Quote
JohnS48plm Posted June 17, 2019 Report Posted June 17, 2019 I've used 2 Daytona kits. They have a better design float valve that keeps the float level even. Quote

Dodgeb4ya Posted June 17, 2019 Report Posted June 17, 2019 On the up return stroke a good accelerator piston pump does create a slight vacuum to refill the piston chamber through an inlet check ball. Quote

rallyace Posted June 18, 2019 Report Posted June 18, 2019 Rebuilding them is simple. I got a kit from the Carburetor Doctor. Everything was there and then some. Beware, the two balls are NOT the same size. Be sure you get them in the correct location. Quote
tom'sB2B Posted June 18, 2019 Report Posted June 18, 2019 Mike's Carburetor sells them. He also has a nice tutorial on how to rebuild them on YouTube Quote

Plymouthy Adams Posted June 18, 2019 Report Posted June 18, 2019 my seal is still effective, but the pressure release valve is a bit more active... 1 Quote
