Especially if they are mounted on the engine itself. Did you put a bit of gasoline down the carburetor throat and attempt to crank it? If you do and it runs a short time and then quits, then you need to get a rebuild kit, clean it, and reassemble.
I have a 58 Chev p/u with a straight 6 (235) cranks but wont start. Has power going to starter, spark through all plugs and wires. Although, the coil is pretty hot ?
