If the carb is right, its not going to change by driving down the road.......I would do a leak down test.....sounds like you're burning
oil.......doesnt need much to foul.........the other .......MSD..........I still cannot fathom why anyone uses that............The plug gap still sounds a little big........the wider plug gap has kinda the same affect as advancing the timing...........hence the foul-up.........
