Oops
Ok so I may have spoken to soon. Then next day I tried to start Marlin again and again nothing. This time Hawg was kind enough to give me an ignition coil to swap out to hopefully get a better spark. I wired up the new coil and got zilch as far as sparks go. Both on a spark plug grounded to the head as well as a prob gaped off the head. I put the old coil back on and tested again with the back plug and was back to week yellow sparks. Next I pulled the front plug out and this time the new thread insert I just installed pulled out along with the plug. So instead of riding Marlin I was pulling every thing off to take the front head off. This time I took it to Billy’s and this morning he was able to put in a 2x oversize plug insert. I also got a new coil. Every thing was buttoned back up and screwed down tight be 2pm today. I still have to weight for the insert to finish curing but I have high hopes. Because with the new coil I am now getting a spark on the plug that is audible. That’s good.
