I think the point of this thread got a little mixed up, it's not about the heater not working, the heater works fine. It's that the engine didn't have enough heat to heat the heater.
AJ, it makes sense what your saying and I think all the more reason I just want to be done with a carb altogether. I'm thinking of going to the Fueltech injection. I don't mind turning wrenches but I get frustrated with timing and carbs, love the old stuff but some areas I just want it to work.
