Well with new pistons and sleeves as long as the valves are sealing then ya should have what your suppose to have . . Now as for timing and jumping timing , well she may have vary well started to shear the key off the either the cam , or the pump drive or both . but really it should not affect the compression. Now what may affect it is a plum slap wore out cam , Keep in mind here that these tractors have had extensive FIELD TESTING and you do not know how it was treated over the many years . even though you set the lash that cam maybe wore down enough that she is not opening the valves like it should. Thus she is not getting the gulp of air and fuel that it should be getting. People use oils that are not meant to be in tractors and yes it will sorta lube it but excess ware will result. The oil that goes into your car is not for old tractors as todays engines DO NOT use flat tappets and use ROLLER LIFTERS and they have now removed the zink from the oils . Just like you read hear all the time for plug fouling and this and that , a lot of times it is the fact that TODAYS GAS is not the same as it was when these tractors were new . And it is causing problems with old tractors . I have seen it first hand on fuel problems and around my neck of the woods we have small farms that are still using OLD tractors everyday to get work done like they did when the tractor was new 40-to 60 years ago . I keep a half dozen 706 gasser going along with 460'560's And five Super M/TA's plus a couple H's and one S/H and i hate to admit as i will probably be banned for here a couple of them Green thinks that no matter how ya tune them they always only run on two cylinder. We have no problems with them as long as we spend the little extra and get the 93 octane gas get cheap and put 87 in them and we have problems . My buddy's 706 gasser is used each and everyday and is pushing 4800+ hours since rebuild and it is a gasser other then one piston that got trashed because the new guy that brought fuel to the farm brought 87 and not the 93 the one time . They paid the bill on that . Yea i know it is a lot of work to tear into and engine But if ya can not find the problem in the timing either in the initial setting of the dist. or in the centrifugal advance then ya got to dig deeper .

Today's Featured Article - Harvestin Corn in Southern Wisconsin: The Early Years - by Pat Browning. In this area of Wisconsin, most crops are raised to support livestock production or dairy herds in various forms. Corn products were harvested for grain, and for ensilage (we always just called it 'silage'). Silo Filling Time On dairy farms back in the 30's and into the first half of the 40's, making of corn silage was done with horses pulling a corn binder producing tied bundles of fresh, sweet-smelling corn plants, nice green leaves with ear; the
