Computer bypass 2100 changeout

No cruise

It's probably because now you have more power. Now the brakes feel weaker. Just my oppinion

 

[808CJ7]

Pretty sure the linkage is binding. Mine used to do that. Would stick open until I stab the gas then it would drop back down. Wound up modifying the linkage from the weber to work on the Holley. Can you take a picture of how you have the linkage set up?

i am trying to post the vacuum diagram i used to set my carb and distributor up. if this doesn't work, its because i am at work and they block photobucket but, i am going to try.

what showed up?

 

[superj]

hey, i cna see it!! sweet

 

[808CJ7]

Superj r u running a mc-2100?

 

[absolutemoon]

I used the original linkage setup and mounted a bracket to the throttle arm and existing linkage pull down. Here's a pic

 

[absolutemoon]

Think I got er. I was using both the old throttle return springs. Just put a new one on and there she be. All in her glory.

 

[superj]

no, i am running a holley but i have a motorcraft to put on. i used that diagram, which i believe is for a cj7 with a motorcraft. when i did my nutter bypass and redid my vacuum lines, i had a weber on it.

i wish i could get ot photobucket at work. i used the linkage from the weber on the holley but had to drill a hole in the throttle arm for it to mount

 

[808CJ7]

I like how you made that bracket. I think you should have the return spring mounted so it's horizontal. From what I've seen they make a bracket that bolts to the front of the carb. So it pulls the throttle forward. I'll see if I can find a picture.

 

[superj]

looks good

 

[superj]

they do, weber sells one and i think you can get it in the performance section at the local auto parts place.

 

[808CJ7]

Here's a picture I borrowed from street2mud.

 

[superj]

you know what, if you flip that l-bracket over, i bet you can take that other spring off, the one pulling down. the one pulling slightly upwards is holding your throttle open a hair, i bet. if it pulls slightly downwards, by flipping that bracket, i don't think you will need that other spring

I'm running a holley also. Mc-2100 is in the mail. Just was wondering if you had a chance to try out the mc-2100 Offroad. My holley craps out on the steep stuff

 

[superj]

no, i haven't i had it on the intake one day for testing and it started right up and was smooth as butter but because of time constraints, i put the holley back on.

 

[808CJ7]

Ok, thanks

 

[absolutemoon]

Oooh!?! Some disappointment. Took her our for her first real drive and found out quick the new throttle return spring was way to tight. Could barely punch the gas. Put a lighter one on and headed back out. She sputters if you punch it and stalled when I tried to turn around. Got to figure this out.

 

[superj]

was it warmed up all the way? if your time is not dead on, it will sputter a little when accelerating if you give it to much gas.

what is your timing set to?

 

[absolutemoon]

Great question. I got my old light out and will check. Have not done it in years so bear with. She was warm though. Correct me if I'm wrong but since I switched the carb, wouldn't that change timing a bit?
