Does anybody know what size IMPCO carburator/mixer is campadible with the 2F? I was thinking 425 but then I looked on IMPCO's website and they matched me up with one way smaller. I plan on building the motor for propane(high compression). Any ideas?

425 is fine for a 2F
That is what I use.
BTW, buy new..
Course I'll see one that needs a rebuild for like $50

Do you trust rebuilt units? Is rebuilding much different from that of a gasser?

Impco carbs get richer as they age. A brand new one will get better mileage..

Are you running open or closed loop. I'm building this rig for trail use only, so I was thinking open loop was all I needed. Any more advice?

currently I am running open. Although I am switching to closed when I get around to putting the new carb on the truck..

I saw where you are running about a 9:1 compression with a turbo. What do you think that effectively raises the compression too? I am thinking 11:1 will work well on a normally aspirated motor.

I am running a tired old stock cruiser motor with my turbo..

the cool thing about closed loop propane is that if the electronics fail you revert back to open loop..

Hey Scott, have you heard anything else about a carb mounting plate?

get a holley butterfly plate (360 would work nicely) and a 2 to 4 barrell adapter.

I've been told the 2 to 4 adapter was a bad idea. Do you know why that would be so?

To be honest I cant remember. I've read so many posts on the issue that they are starting to run together. I might be confused with using a dual carb to single carb adapter.

I left a message with the propane guy, hopefully I'll hear from him soon.
Heard from Roy(propaneguy) and he told me to ship out the mounting plate from the carb. I'll keep you posted.
