hi yea Im having trouble with car reading hot never boiled over no leakes could be timing I flushed radiator but im fairly new to flatheads never done timing not real familiar with it it runs really well other than gauge reading hot gonna try new gauge I had it idling in driveway for about 30 min last night and put heat gun on it the gauge went to hot and I got readings from about 190 to 210 in some spots
just checked spark plugs and some are covered in fluffy black a couple are cleaner I put in new power valve about 2 months ago from vintage speed because old one wasnt right a causing it to run rich put in new plugd then too and now some of these are black too but not all maybe this is whts causing it to run hot well gonna do plugs today too
