Hi Norm, I took apart two PTs I was given last week. One had good bore piston but worn rings and shot base. The other was 30 years old...... rings seized in, but I got one out, it was good and used a Sabre Victa base that had a Briggs on it. I like to take the rings off to decoke them. and replaced front carby primer with another good one, new fuel lines.... I find all sorts of problems and missing parts, . I didn't do the mod on this one yet, but I have done a few and they worked OK... This one started after a few pulls. let it idle for a while , got low revs and higher revs......... I'll have to mow a lawn to see how it goes, but looks OK nice solid base good wheels.....
But you have to check you have a spark........ visible or do the feel the plug test........... I don't do that one....
cheer all specially pau 13z cheers speedy Bundy.... Our june rainfall is worst for 17 years......................................
