Four years ago I bought a beautifully built 29' highboy from a fellow HAMBer. The car was professionally built in every way by another HAMBEer. It has a 350ci crate engine with a Accel 71100E distributor, Accel Super shot coil and a MSD Street Fire spark box. Every spring (after sitting out the winter in a very dry but occasionally heated garage) when I try to start it it will not fire. It is getting fuel in the carbs fine. For 4 years it has been the same drill, turn it over, no start. Start to do a electrical component check (got as far as the coil and spark box which tested fine) and when I reach the point of quitting, it eventually fires right up. This is after several attempts at spinning it over for awhile. The wiring in this car is excellent. I have two friends who are automotive electrical experts and they are stumped. Once it fires, it runs fine all summer, has never stumbled starting once it fires for the first time in the spring and runs fine till I put it away and try to start it after it has sat all winter. I have put about 1000 miles on it every summer without a single issue. It is driving me crazy, any suggestions why this happens every spring? Thanking you in advance for any imput.
