Dual Quad SB

No I don't just going by how it feels and how quickly I can pass up these newer cars. I do have some wide open muti lanes roads with speed limits as high as 70 mph (one even has a stop light right before it.


Maybe its more about the same power overall but it does feel better down low part throttle but wide open down low in 3rd gear its not quite as good as my Demon DP 650 was. At higher rpms or in lower gear were revs come up fast and easy its just as good--I say a bit better.

I need to work on getting the secondary air valve open sooner. If I had Edelbock AVS carbs I could just adjust the spring but with the AFB carb is grinding of weight to make the secondary open sooner. I have hear and old trick was just to remove a valve from one of the carbs. I will try that as soon as I'm sure the jetting is right on. Its very close but might try .074 jets in the secondaries (lots of fun changing two carb jets..about 20 mins it takes me but like to do it with the carbs cool so not to pull any threads out. I had .080 and it was too rich..it was good until I went fatter on the primaries..but it needed it.

Edelbrock AVS carbs are adjusted at 1 1/2 turns for the secondaries vs 2 1/2 turns for non dual carbs...so it very well needs to get some weight off those secondaries air flaps..

I have an old tuning carb mag from Hot Rod order off Ebay last week from the late 70's, it has advice on tuning dual carbs. I'm going to look at the pictures and see how they used to take the weight off back then..it should come late this week.

Maybe I should have just got Edelbock AVS carbs..but you seen the prices / I got these carbs and tuning kits for $420 and the carbs were new..Edelbrock was like $400 a carb for the AVS.
