Default Re: My model A wont go faster than 40-45

Question to you gurus.

This might be the thread to ask a torque question.
My tourer had torque, it could almost be shifted to top at walking pace. I have replaced the spark plugs with new, the smaller diameter thread type with an adapter spacer. It is correctly timed and correctly gapped but lost much of that torque. A shift on the advance/retard lever makes no difference. I notice the gap in the old plugs is much bigger than the new.
Question. Would this gap be the cause of reduced torque.
