Any suggestions appreciated. Fiat forum for my model is dead so im seeking even generic level advice as my experience with classics is minimal.
Details:
72 fiat 850 spyder
Water cooled 0.9L 4 cylinder rear engine, points distributor, 2 barrel carb, mechanical fuel pump
The problem:
10 secs after starting the engine, my header basically starts to melt off. The factory paint dosnt just smoke, its bubbling and dripping off ( font stuck on bold?)
My gut says it's extremely lean but ive never experienced this before. That amount of heat so quickly has me fearing to run it at all to put the evidence on the new plugs. I got 1000 extra parts with this car but an extra head wasnt one of them.
Carb was soaked for 3 days in a berrymans bath, jets gone through thoroughly, all gaskets and diaphragms replaced, float height set etc. Tested for vac leaks and found none, has fresh quality gas in it.
My carb experience is 99% from motorcycles so either im missing something or the more complicated design of car vs bike carb has me hyper focused on it
What do you guys think?
