Thanks guys for the thoughts on it I’m leaning towards the carburetor was too lean that it in , plus I might’ve had the timing off too much. OK appreciate input I’m going to try it one more time and see what happens thanks a lot I’ll let you know ,hopefully get it back running in the next two weeks

I will reply to everyone who answered thanks again

Sorry it won’t let me put any more reactions today

Hi thanks all for the replies and yes you’re all right I should I give more information here’s the story I bought the truck in 04 . 21,000 miles on it took the fire bed off put a dump bed on it started hauling Sand and gravel ,at 24,000 miles the Pistons melted down through the side on one piston all the way through the rest of them was halfway burned through, sent them to a machine shop on the West Coast, they tig welded them up re-cut the rings ,supplied rings and racing shop that I had put it together took the cast strings and threw them away and put in chrome Molly, I run it from 24,000 miles to 27000 and they broke all the rings in it every cylinder , had it board out ,honed 20,000 over with no’s pistons,in a machine shop in Harrisburg PA , he had built these engines in the 60s did a great job on it brought it home ,started it up had less than one hour on it idling and running part throttle, and all six cylinders cracked the rings all three sets of rings ,I believe I had an out of time too much ,so it’s my fault ,I was just wondering what everybody else thought about it thank you very much for your replies and the help

Dang auto spell I know I corrected that before I posted it breaking rings 707 gas engine it broke the rings initially at 24,000 miles and again at 27,000 miles what could be breaking them

hi is there any old-school mechanics that work on the 707 engines particularly 707 say having problems breaking ranks I have a seven day or 608 was 27,000 miles and it’s broke the rings twice and it wondering what could be doing it any ideas thanks
