Check the points. The gap may be too close.

Hi Darrenz,  Hot restart problems are usually due to the fuel boiling or vaporizing in the carburetor in hot weather. Alcohol in the fuel aggravates this problem. It can also cause vapor lock in the fuel pump and fuel lines.  Fuel injection solves this problem!  Gary Hammond,   |

Is your engine top sealed from the bottom? Could be heat soak. Did the problem just start recently?

Hi Dan, Is your engine top sealed from the bottom? Could be heat soak. Did the problem just start recently? The GT engine compartment is a lot more open than the twoie, and would be pretty difficult to seal up like in a bug. But wrapping the exhaust would help greatly as well as anything that would deflect the radiant exhaust heat away from the top side. Gary Hammond, |

Sometimes just slightly retarding the timing will help. Advance timing makes for a great running engine (higher r's), but sometimes makes starting difficult. If the advance is not functioning right it could be set too far forward to make it run best at the mid to top of the rpm range.
Just a thought....
Regards

Thanks guys I'll check that out. it does seem to happen more on the hatter days. the heat riser tubes are not connected to the exhaust. and I have never had a timing light on my car so I think I will check that first. thanks

Additionally, as jspbtown noted in another thread, having valves that are too-tight can also make it so it will not start hot. When I first got my VW bus (before checking out the engine), it had this problem. However, if this is the case you will ususally notice that it seems to be turnning over easier/faster when hot (because the open valves are not allowing compression to build up). Adjusting the valves solved the problem completely.

The timing mark on the block is where the 2 halves come together just below and slightly to the right of the fuel pump.
