New motor, coil, wires, plugs, ign sensor in distributor. Motor idles like a champ. Runs good for about 45min then all it will do is idle anything over 2500 rpm it spits spurts and backfires. At one point it would not start so I moved the timing to get back to dock. Im thinking the ign amp might be getting hot and not working right or else fuel is boiling in. Carb. Any thoughts? ??????? Im lost here. Thanks for reading
