OK, first, I am thrilled to be asking this question at this forum because I have dreamed of owning a CJ since I was 16. Bought my first CJ7 a week ago and have already had a blast playing with her. However, I think I'm outside my skill zone because I just can't seem to get her running well. When I bought her, she wouldn't curb idle at all and would stall every time I came to a stop. I pulled the carb off (stock Carter BBD) and rebuilt it. Set the floats/accl. Pump/choke etc. To the specified dimensions. Mixture screws are about a turn and a half out. Replaced the plugs and set the timing.
What keeps happening is that I will set my curb idle (about 800RPM) and then take her out for a spin, and all of a sudden it's idling back up around 1200RPM. I pop the hood and the fast idle cam is not engaged but the idle is way high. So I turn down the curb idle to around 800RPM again, and then after a little driving, she'll stall at stop lights. When the idle is high, she diesels a bit when I stop. When the idle is low, no dieseling but the exhaust smells rich. Actually, she always smells like gasoline which probably means I have a leak somewhere, but one problem at a time. When the idle is low, I get pretty decent power throughout all RPMs. When the idle is high, my high RPM (3000 or so) power is not so good. Also I'm burning through gas like crazy. Might be the leak (don't worry, I park her outside).
OK last thing. When I was setting the timing yesterday, I noticed that the inductive light wouldn't flash at a consistent rate all the time. It would pause which actually coincided with the engine chug/struggle. I've ordered a new distributor cap, cables, and rotor and will install them this afternoon. I've never set a dwell angle before, but could that be the problem? When I go into the distributor I'll check and make sure the rotor shaft isn't loose. Thanks for any feedback.
have the same problem?
