Got a Capri, nice low milage, 2.0 pinto engine with a twin weber carb.
Starts and drives really nicely from cold, even once it's warmed up. The problems start when you turn it off and return to it while it's still in any state of 'warm'. It takes a little while to start, turns over for a while (battery is strong) and then catches, sometimes with a little help from a jab of the throttle. Then it will proceed to run like it's misfiring for a bit, lump, like your being really 'jerky' with the throttle. It's not undrivable, just really uncomfortable. After a few miles, most of the time it sorts itself out and runs lovely again until you repeat the above. Doesn't matter if it's a few minutes after you've stopped it or (if it's warm enough outside) an hour or so.
My only thoughts are that it's running really rich when warm, thus over fueling? But it doesn't seem to smell strong or anything though.
Could it be a timing issue? Bit lost here!

Auto choke? If so maybe funked so when warm over fueling. Pintos are about as basic as it gets lol.

where are the fuel lines? keep them away from heat if possible,
Edit did a google
quote:
HARD STARTING, HOT
Difficult starting of a hot vehicle from 5 minutes to an hour after the engine has been operated, can be caused by the volatility of modern fuel. If you have this problem; try using the following method to start the engine: DON’T touch the footfeed (VERY important). Crank the engine over from three to 5 seconds (different vehicles will respond to different times); and then GENTLY (so as not to activate the accelerator pump) press the footfeed approximately 1/3 of its travel. The engine should start, and may run rough. Run the engine at a high idle for about 10 seconds. This issue is caused by volatility of modern fuel. Once the engine has been shut off, the gasoline is heated by the latent heat of the engine, and percolates the fuel from the bowl into the throttle area, forming a mixture that is too rich to fire. If you push the footfeed to the floor (as has been the traditional method of “unloading” a flooded engine) the gasoline continues to flow into the engine (again due to the volatility). By not touching the footfeed, you do not open the throttle plates, and the engine will pump the overrich mixture out of the tailpipe. Once the overrich mixture has been alleviated, gently opening the throttle will allow the engine to start.
