    630 lpg

    Did a compression check on the 630. The #2 cylinder was at 40 on the test! Going to do a valve job on it now! Since we got it off doing a rings and pistons. Looking online for LPG pistons is a needle in a haystack! Thinking about using old pistons with new rings! Had anyone done that? I had always gotten both new with new sleeves in other projects! It was a cotton picker at one time in its life!

    It is an LP engine, I would make VERY sure the rings need replaced,,

    My experience with LP is that it is almost impossible to wear out engine parts,,,
    Some of the tractors include JD 4105, JD 855, JD 650,,,, and,,, the IH 584 4WD
    My favorite attachment is the homemade landplane,,, EVERYONE needs one of those!!
