Hello,
I'm a new member, but the first repair I have done to her(still need to name her), was changing the spark plugs. I got the old ones out and she needed new plugs so bad(see attachment below). Put in some double iridium plugs from Bosch. And after I relubed the plugs with the silicone jelly and plugged everything back in, only one side of the head is backfiring in the muffler. Still need to find out if im running just slightly lean to have this happen, or if some wiring needs to be replaced. I did notice one of the plugs was drenched in fuel when I removed it. Maybe 1 cylinder isn't sparking off... anyways if y'all have any experience with this, I would love to learn! Google gives bad advice!
