E85 on Weber
I have a 12a street port. Which I'm planning to convert to E85 an PP.
I have a Mallory 140 Comp pump and a Mallory return style regulator. All -6 lines. It's a 51mm IDA Weber with extended fuel bowl. I feel like I have all the ingredients. But I'm not sure how to set up the Weber.
Racing Beat reccomend this for a 12a PP on pump gas:
Venturi - 43mm
Fuel Jet - No. 235
Air Jet - No. 130
Emulsion tube - F-8
Needle valve - 300
Where would I make changes to run on E85?
Also, timing. I have a locked dizzy and I'm only running the Trailing plugs on a tfidfis set up with MSD coils set up as coil on plug. Not sure if I would need to set a pretty decent advance or not.
If anyone here has done a Weber on E85 I would love to hear your experience.

I don't have a wideband on it right now. So it's all guess work. I think that should be step one here.
I do have a 3.0 glass ball needle valve, and I know the pump can handle the pressure. I might just try dumping some e85 in the fuel cell and see what happens. I have 5 gallons of it sitting there with nothing to use it on. Worst case, it won't start and I have to drain it.

I prefer E85 for many different reasons. One reason being the cooling effect it has on the engine. Which helps in the Florida Summer. It's also been shown to produce more power at the end of the day compared to pump gas in most cases.
I also am converting 2 of my other (non-rotary) cars to E85 as well. But that's much easier since they are fuel injected and both have an AEM ecu.

you need like 30% more volume compared to regular gasoline, so it'll have bigger jets.
