I have a JD mower with a FS730V that has an intermittent smoking issue. The motor has 313 hours and it works great minus the thick white/blue smoke it generates ever so often. I did a compression test and came up with 90 on cylinder one and 92 on cylinder two. It also appears that I may have some gas in the oil. I’ve recently changed the plugs and oil but the smoking seems to be unchanged. I’ve ordered a new fuel pump but was curious if anyone has any other suggestions. The motor seems to bog down right before it begins to smoke but the smoke stops after several seconds.
