258 Carb problem

XJay96 · 10-10-2005, 03:08 AM

Just finished the resto see post here: http://www.jeepsunlimited.com/forums...d.php?t=678528
The carb needs adjusted, Jeep always wants to stall, we seem to get it dialed in, but when you get driving on it, or if it sits long enough it starts stalling on itself. Anyone know if I am missing somthing or doing somthing wrong to keep this thing running on its own? Could it be the timing?

A lot of times, if you've tried to dial in the timing and carb settings and it still stalls, you probably have a vac. leak.

I'd check for the vac leak first, then move on to timing and carb settings:
If you have a vac gauge plug it into a manifold vac source (I use my brake booster line) and set the timing for max vac, then adjust the idle mixture screws for max vac.
