Sorry I cannot help just not qualified to comment on this sort of problem. My Palmer qualifications are more around 1910 than 2010. I am sure there are folks on the page who can give you advice.

There are many possible reasons for your "backfire". Ignition crossfire under load and/or sticking valve (usually exhaust), broken or weak valve spring come to mind. Both are common, but no means the only culprit. David

You should be able to find ignition parts as those engines were used many places. If you have the number off the distributor i could look some.
