The Stovebolt Site Forums The Shop Area Engine Shop Adapter 1 BBL to 2 BBL

I have a 216 being rebuilt at this time and am gathering parts and info for install. I was thinking of the Fenton Headers and using the original intake with an adapter for a 2bbl.

I am going to use a electronic ignition,either Pertronics or Stovebolt(any preferences?)

All the posts on the headers have been very positive.

I read a very long post from July on the adapter and was very concerned. The poster had a myriad of issues with the adapter and carb.

As far as the carb,I can always get a used one with a manual choke.

My question is will this setup work well on a 216 .I am not looking for great shakes on performance,just reliability.
Secondly ,should I buy a manufactured adapter or make my own?

Langdons sells an adapter, and a carter/weber carb. They're pretty cheap, and many people here have used it with good success. I'm going to run two of them on my fenton intake, myself.

I bought two of the Stovebolt Engine Company carb adapters this past June. I had no issues with them - they looked good and bolted on fine. I cut off and ground smooth the "extra ears" but that is not necessary.

I think that this is the adapter. Maybe someone else will confirm that this is the correct adapter.

Yeah, thats the one. I'm pretty sure it requires a SMALL 2 bbl. As in you cant use Rochester 2-jet, or Holley 2bbls. It's perfect for Carter/Weber, and Holley/Webers, though.

So you're saying that the 216 can handle a 2bbl carbuerator

That, I don't know. I do know that the Carter/Weber is the smaller one from Langdons, AND it's progressive! I would'nt be afraid to try it.

You'll have to fiddle around with the accelerator linkage. The Carter-Weber is a real nice carburetor and Langdon's sells it at a good price. You might want to call Tom Langdon - he's a nice guy and he will tell you his opinions regarding this carb on your engine.

It might not improve your performance but, if it is not too much carb for a 216, it might improve your starting reliability and give you a little better performance. You will have to wire-up the automatic choke (mine are electric).

I guess that's the question, can the 216 handle it ?

just-a-hacker,

IMHO, it's too much for a 216. You won't find any gain and you will probably suffer both in performance and mileage. The basic idea of putting more fuel down the same hole on this small engine is flawed.

Take this at face value as I'm certainly not Stroker McGurk.

Any suggestions on what carb would be best for his stock 216?

I don't think this will be too much of an issue, because of the progressive feature of the C/W carb. When the throttle is at lower settings, only one bbl is open, and it's smaller than the stock carb. I don't have alot of experience with the C/W, but you might be able to adjust the point when the secondary opens, and tailor it to avoid the too big of a carb bog. I would call Tom Langdon and ask him if this is the case, or if he has any experience with someone running it on a 216!
