Low Idle

Why do I only get blue smoke at low idle and not at med. or high idle? Other that that Ernie runs good.

Engine vacuum. It's more than likely sucking oil through worn valve guides. Higher RPMs - usually lower engine vacuum.

thanks Eugene. Should I think of an engine rebuild? Where do I get parts for all my other Farmalls? Great places for Cub parts but I dont know where to get others.

Marc:

There are a few places that come to mind immediately for parts for your other Farmall's.

One would be JP Tractor Salvage for used parts. Also there is a National Use Parts Directory that Jamie and John have access to and can find your needed parts across the US.

Also, post a want for the parts you need on the For Sale/Wanted Forum and many of our members who have other models may have what you are needing.

For new parts you local CaseIH Dealer or contact Ken Updike at Carter & Grunewald.

Hope this helps

As long as the tractor runs well and does the work you want - I wouldn't over haul. A quart of oil ever so often in the crankcase and perhaps changing the sparkplugs when they foul - is a whole lot cheaper than an overhaul.

Parts. It really pays to shop around for tractor engine parts. I get tractor engine parts from one of my local autoparts stores. I make a list of needed parts then ask for prices. I frequently get the sleeves and piston set from one dealer and other parts from a second.

Also check for parts and prices at other brand tractor dealers.

http://www.Valu-bilt.com

Ask for their free catalog. Right side of the first screen. It is a handy reference and will provide a pretty good idea of parts prices.

If the problem is indeed worn valve guides, your only REAL option is to take the head to a machine shop. They will press out the old guides and then press in the new guides. What a lot of folks don't realize is that those new guides will then need to be reamed to the exact size necessary for the valve stem that goes in it. This NOT a job that most of us do-it-yourselfers are equipped to handle. The proper tools are way to expensive for the occasional use we would give them, and it also requires a bit of knowledge and expertise that the average tractor owner does not have.

Is this a cub? If so valve guides are in the block.
