just got some blown headgaskets replaced and it drove great for maybe 60 miles. then cylinder 3 quit firing any at all but i smell gas so it must be a spark problem. It started happening when i was doing a 4th gear pull. any ideas what my problem is ?
is it a constant misfire? usually misfires that happen after pulls mean cracked ringland and destroy spark plug. check the spark plug, if it's damaged, borescope your cylinder to examine the piston for missing chunks along the edge.
