Check your timing marks you may be out of time. Check this box to be notified of replies to this topic. Note: BBcode and smileys are still usable.

There are a few things that can cause it to back fire. Are you sure that you have the wires on the right cyl. If it is running too lean. Timing is a bit hard to mess up, unless you bent the linkage, A leaking head gasket.... wrong one, not torque right, or warped head

That motor is now a Classic. For more help go to the AOMCI's Ask A Member site. We have many members that can help
