Thanks for the suggestion. I
ll check them out carefully. Yes, it is possible I could have gotten away with a service tech cleaning and pattern check.

I hope there is a good explaination for the difference--and why do some seem to be having the nailing problem?? Better ignition characteristics or earlier popping-off???

BTW, a query to Diesel Giant hasn't had a reply yet in a few days. will this be a problem?
