1983 S10 Carb Swap

[michaelf]

I have an 83 S10 with a closed loop carb. I bought a fairly new varijet carb off another 83 S10 that does not have the 2 electronic connections. Is is possible to use this carb on my truck? Any help would be great. Thanks.

If it bolts right up, and the cables work out you can make it fit.

I really can't imagine you having any gain with the swap at all

The carb bolts up, but the check engin light comes on (I'm assuming because of the 2 connectors that have no place to hook up to the new carb.)

Yip, that carb is not meant for that truck.

It needs those connections. Replace with the original. I really don't get why you replaced it if the other was working properly.

Put your money into worthwhile mods such as a free flowing muffler and intake.

the orginal carb from my truck is shot. The throtle shaft is loose where it goes through the side of the carb body, creating a vacuum leak. I had hoped this other carb would work.

don't use it if it doesn't have the appropriate sensors and connections.
