it started to idel but as soon as its warm its stalls very bad very jerky. Is it this thermovalve that we talked about in partI. i can get a new carb for cheap would that fix it?

It sounds like it could be a few things.
1. Vaccum leak in intake manifold- replace gaskets and seals
2. fuel mixture too lean/too rich- adjust float level settings and adjust idle to normal range
3. Bad plugs- plugs may be covered in carbon, atleast clean them off, if not get new ones. Make sure you're using NGK's

Just because I use an old distributer cap as an ashtray does NOT make me a redneck!
i was hoping you wouldnt say plugs cause 2 of the 4 are cross threded how do i fix that?
can anyone one listen to me ever? ok there is a vacuum line underneath the air bix, looking from the front of the car(radiator) and look at the carb, right on the left behind it, there is a vacuum line that connects to the air box. My bro had this problem(found it fast thought) the air box was off and when cold it would idle fine, but when it warms up it would idle poorly. You may have a crack in the vacuum line or it could be unpluged or unhooked, jsut check it before you waste time and money

Sometimes a thread chaser will work. They also make heli-coil kits designed for spark plug holes. You have to tap out the spark plug hole to the heli-coil size & thread the insert it. The catch 22 is not to get shavings down in the cylinder walls. You can use a vacuum, grease on the tap, or blow it out with a special extention on a air nozzle to get the shavings from getting into the cylinder bore..Originally Posted by akylem

RE cross-threaded spark plugs,
I had the same problem with mine, and the $25 helicoil kit did the job. The threads on the bad hole were so bad that the spark plug actually dislodged from the engine while I was driving -- made a huge racket! I though I'd had a blowout.
If you keep the car, you'll need to do this anyway because
(1) the plugs should be replaced every 30K miles
(2) a cross-threaded plug will not have the same thermal contact as one that is well-seated, so the effective heat range of the plug may be wrong for the engine
