Hi, I have looked at your save game and have come to a concussion. I took out the rocker shaft and alternator because they had the most wear so I replaced those. Also, the battery terminals were loose, so I tightened them. then it fired right up! I suggest getting a tune because it's backfiring a lot. I would just do a full engine rebuild because most of the parts are nearing the end of their life. hope this helped! Let me know if you need any more help on Discord @VladdyPaddy #7245
