okay i did a search and only found jetting information. my uncle told me to leave the jetting alone and get a 30cc or even better if i could find a 20cc accelerator pump kit instead of the 50 thats on it. its a holley four barrel not sure of the cfm on a 83 12a sorry for the lack of knowledge

 

need more info bout the problem ur having. off the shelf holleys don't really work well on rotary but can be done if u have the time and patience. i've use a few of the ones from RB with no problems.

 

sorry wasnt thinking it hesitates in the lower rpm when the gas is hit, its a 600cfm which is probably way too much for the car

 

the RB setup for stock port is only 465cfm. a worn cam that works the accelerator pump may be the problem. with the engine off, work the throttle by hand while watching the nozzle. it should squirt gas as soon as u move the throttle.

 

it does squirt gas in i just think its too much and chokes the car out. it has a 50cc accelorator pump
