Low rpm woes

[patricke1971]

I have an ongoing problem..I have a 2332and previous was a 2234 and have the same problem..under or around 2000rpm it seems to miss a bit, idles perfect at 850 rpm.

I have changed distributors played around with timing changed idle jets ...after 2000 it takes off like a rocket..
The only thing I didn't change is the carburetor..it's an Spanish idf center mount..

I currently have 65 idle jets..

And currently running a 010 distributor with petronix..

replace with CB low profile intake

I have no choice..dual carbs simply won't fit..it's on a beach buggy ..after 2000 rpm the thing is a rocket...

Red light to red light I have raced quite a few different cars and won.
I have 295 50 15s on the back and it will spin the Machine sideways..

Lol it's just under 2000 rpm Is where it's a tad sluggish

Maybe switch to a 123Tune distributor so you can use whatever vaccum you have in the manifold to dial in some extra advance just off idle, or ramp the centrifugal curve a bit faster off idle.

That must suck as even driving with a stock cam 1641 the engine only works above 2000 rpm ..

Agree on the distrributor. If it has to be an all mechanical, go with a 019 or a Magnaspark or Shockwave.
Header is too large for the power window, so there will be a good deal of overscavenging.
If you run the stock 36 mm venturis they are likely too large. Go 2 mm down and rejet.

Right now I have an idf 48 with 40mm vents..I have a pair of 36mm would they work better?

[modok]

40mm vents.....That's waaay too big for what the intake manifold can flow.


a pair of 36....... whats?

[jinx758]

Accelerator pump squirt off?

Double check dwell. Nubs, putting, & gap off can cause that symptom.
Hope it's something simple.

Sounds like a fun ride ... stay safe
