cold start problems
 

my 1984 rx7 has no trouble starting when warm but after its stood over night it just won,t start unless its a push start. Whats the likely problem/solution
Thanks

I'm going to asume that you're talking about a 12a carbeureted and not a 13b FI. Are you choking the car when you try to start it? Pull the choke out all the way, crank it until it tries to start. After that, push it in 1/3 of the way (2/3 choked) and try again or keep it running. When you're driving, either push it in all the way (no choke) or 2/3 of the way (1/3 choked).

It should be cranking at around 250rpm. If it's flooding or not cranking at a decent speed, check your battery and starter.

No starter motor has just been rebuilt. Problem was solved by pouring some petrol down the carb - so latest thinking is a bad accelartor diaphram.
