I will check the spark next time this happens. Honestly, it acts as if it’s not getting any spark, no attempt to fire at all, even with starting fluid. I have heard in the past that coils can fail at high temperature, don’t know if this is true, or not? I have a spacer between the carb and the intake although I just ordered a new spacer I can’t imagine it will make a difference, but I am willing to try about anything right now. I have considered installing a homemade shield around the bottom of the carburetor to deflect some of the heat from the exhaust manifold, but I always get stuck in the idea that it was hot in 1949 and the engineers didn’t seem to think it was necessary. Thanks for your thoughts and if anything comes to mind let me know!
