Carb problems...

[FJAggie07]

Alright I am throwing a new carb in the 40 but it has an electric choke and well the 40 didn't originally have one of those. Anybody know anything about chokes, and can i just go pick one up at o'reily's and throw the ***** in there and hook it up?

I am fawking clueless at anything electrical...

[Reckless]

I could come by later and help ya. But yea ya could just throw a electric carb on. Just need to find an ignition hot wire to tie into.

pick up a choke?

If the carb has an electric choke, all you need to do is hook up power to it, which on my edelbrock was two wires. And if the wires came off then it went to full choke.

Ok I think I figured it out while at my automation lab, I was freaking out cause I just had too much **** going wrong with this carb install, but I think i am going to be ok. I found only one post on the choke of my carb so i need to find the second post and figure out which is positive and negative so i can ground off one and then tap into some keyed source for the 12v. Man I am tired of **** going south on this damn truck.

If it's only got one terminal on the choke, it grounds through the carb housing more than likely. So that would be your positive.

any pinging?

did you set it to whatever base advance I wrote down?


I couldn't find any timing tables for the 258 so I hooked up the drb2 scanner to my brothers 4.0 yj and just used whatever vacuum and advance it displayed.

[colman]

Make sure you're not using the coil hot wire to power your choke. The choke can suck a lot of juice cause it's basically powered on the whole time, causing you to lose some of your spark.

Personally, I woulda just stuck with the old mechanical choke carb. I rebuilt the carb in my old 72 FJ40 and it ran great. I like having the mechanical choke, just like most other mechanical vs. automatic devices, cause it puts you in control of the process. It just sucks when you forget to turn it off. ;)

Actually I was getting really tired, and I quickly ran the choke into the headlights. I didn't set the choke screw just right before I ran it home and it ran like a scalded ape the whole way home hitting close to 85 mph of certain stretches of 45, and I knew then that I had screwed something up. I got it to my ranch played with the choke screw, idle and mixture and throttle cable and got it idling a LOT lower but now i need to fix my throttle cable cause I cut the housing too short and it is acting like a governor...oh well. Then my dad stuck the damn thing on the front of our property cause the tires are so bald...

Got to use my winch...so no harm done.
