Got one on my 600cfm holley on my 13b (I know but you guys discuss holley's more than the 2nd gen forum). Deal is....I can get the damn thing to idle fine and I can get the mains set right but I have a horrible lean studder in the intermediate circuit from like idle to about 2000rpm. I either have to pet the accelerator or stomp on it. Any slow acceleration will result in popping and bucking.



Unfortunately, I bought the carb pre built from Rotary Engineering and have no real experience with the system. Anybody familiar with this system? Rotary Engineering seems to have fallen off the planet. They are not responding ot phone or email.



Thanks gents,

i have no idea what that is, and rotary engineering has been out of buisness for like a decade.

um is it possible that the intermediate circuit is clogged? i gather the holley doesnt have a jet just for that?

Well, Rotary Engineering, that name was bought a few years ago. They're out of Burbank CA now. Builds holley and weber setups now.



That's who I bought the carb from.

oh really, i had no idea. they had cool stuff back in the day
