Greetings to all!
  I tried to post this question yesterday but it never made it 
  - so here goes again.
  I have a 75 Gremlin w/304 - 40K, Hedman headers, Edelbrock manifold and 
  carb. No internal engine work. 
  Starts cold no problem. Starts hot no problem if I do so within 5 to 10 
  minutes after shutting it down. However, if I let it sit 30 minutes or 
  so, she is very hard starting. Edelbrock tech suggested a "percolation" 
  problem. So, I put a heat sink gasket between the carb and manifold. This did 
  nothing to solve the problem. Anyone ever experience this before? I sure could 
  use some help!
  Thanks, 
  Charlie
