Hi all
I have a very strange problem with a '78 351M motor with a 2 barrel carb. The motor itself is sound and very good as far as I can tell. But here is the problem. I can start the motor and get the motor up to normal running temp. shut it off and restart with no trouble. But if the motor sits idle for more than 1/2 hour it will not start again for 5 hours (or until cold). It is as if the motor floods itself while sitting for this period of time. I have tried a new carb on the motor, but still the same problem exists.
I am totally baffeled as to what the problem is. Can anybody shed some light unto this for me? I would like to keep this motor as it is in great shape for a '78 block
TIA, Bill
