I'm in love.
Cool! What speeds were you guys messing around at?

Yeah, the choke... only when its cold... after we rebuilt mine, the choke still needed to be adjusted... she wouldn't want to stay running when in gear at idle on a cold start... I remember backer her our and it nearly stalling... the RPM went down to 200RPM, the low oil pressure and charge lights came on, I would be feathering the gas, and she would pick back up.... keeping a 7.0L big block running at 200RPM was fun.... never did get to adjust that choke.

is that easy to adjust, or cheap to have done? its sort of annoying to back out of the driveway, and have the thing stall with the kid next door looking at it like \"what a hooptie\" I want to race him.

The choke is electric... so there isn't a classic adjustment on it that I know of, I know it can kinda be set durring a rebuild....

there are two things you can do... first, let her warm up for a few minutes... its not fuel injection, they will need to warm up when cold..

or... as what I did, learn the drive it when cold using both feet, feather the gas and keep the RPM up using the throttle and use the brake to control speed while backing up.... it was fun and sound cool too .
