    old MF-135 diesel - constant blue smoke

    OK, Thanks. I've got to drop the oil anyway to see if any diesel fuel is in the crankcase. I haven't been able to smell any fuel on the dipstick so I'm hopeful there's no fuel in there. If there is any fuel in the crankcase then I won't use it until a cause is found, but if no fuel in the...

    old MF-135 diesel - constant blue smoke

    ptfarmer, since yours has been like this for a while, have you experimented with different weight oils to see if the different weights make any difference? The oil was just changed in this one with new 10W-30 Shell Rotella (according to seller). I was wondering if diesel 15W-40 or diesel 20W-50...

    old MF-135 diesel - constant blue smoke

    Thanks ptfarmer, hopefully I will be able to use this one as the troubleshooting continues. When first cranked it emits a bunch of blue smoke, but then as it begins to be used the blue does slow down to a thin haze and doesn't look as bad. As Dieseltech suggested, I've ordered a fuel lift...

    old MF-135 diesel - constant blue smoke

    Thanks Dieseltech and MF135 Diesel, I will make some checks and report back. I'll drop the oil this week and see if I smell any fuel or anything strange in the oil. There is no fuel smell on the dipstick. I think the fuel is a mix of old and new as 3-4 gallons of fresh fuel was put in the week...

    old MF-135 diesel - constant blue smoke

    An old friend offered me a MF135 (1966) diesel that runs good & sounds good but emits constant blue smoke. I watched the owner bush hog an acre or so and the tractor performed well and safe to say also that there were no living mosquitoes in the area when the bush hogging was done. The...

    MF-135 Gas Perkins - fuel flow

    Thanks Bowtie & Valley for the info. It sounds like we had similar issues. I did straighten out the low fuel flow by removing the sed bowl and running a new fuel line to the carb and wow, then lots of fuel flow, BUT, still engine not running right and back firing. The reason for not...

    MF-135 Gas Perkins - fuel flow

    Thanks Powrguy, great info and something that I never would have thought of or suspected. I'll report back after I change out everything in the fuel line and check the tank.

    MF-135 Gas Perkins - fuel flow

    Thanks Dexter, I got the filter from Yesterdays Tractors as the exact one for the 135 Perkins Gas, and it looked identical and the tractor ran ok for a while and then something stopped up to a trickle, so it could be the filter, don't know yet if tank or sed bowl screen (no debris visible) or...

    MF-135 Gas Perkins - fuel flow

    Many thanks Valley, there is a shield on my 135 behind the exhaust manifold that butts up to the sed bowl. Did your 135 have this shield and then you made another shield, or was this shield missing on yours? When I look at this shield I can't help but think how it must transfer the exhaust...

    MF-135 Gas Perkins - fuel flow

    Hi BR, Many thanks for the info and troubleshooting steps, very timely in my case and much appreciated. When I got tractor (just last month or so) it had a cracked sed bowl so I purchased a new sed bowl assembly but installed only the new strainer, gasket & bowl since fuel tank was near...

    MF-135 Gas Perkins - fuel flow

    I purchased a couple of pint jars today and then did the fuel flow test. The result was approx 1/8 pint thru carb in 2 minutes. And nothing more than a continuous trickle. Soooo, guess I'll start up the line from carb to tank. I also got two extra 5-gal gas cans to have for draining the tank if...

    MF-135 Gas Perkins - fuel flow

    Well, I just had to go out to the shop and try to run a wire direct from the battery pos terminal to the coil (new) pos terminal to see if wiring, ignition switch, etc, is the culprit, but the situation is still the same, the tractor runs at first sorta like an old hit-and-miss engine and if I...

    MF-135 Gas Perkins - fuel flow

    Thanks Clayton for your response, With a search I found an old thread of someone with a similar problem. https://forums.yesterdaystractors.com/viewtopic.php?t=1355978&postdays=0&postorder=asc&highlight=fuel+flow&start=15 That thread said a pint jar should fill in 2...

    MF-135 Gas Perkins - fuel flow

    I'm having issues with my MF-135 gas (Perkins) that keep me thinking insufficient fuel flow but not certain, so I'm looking for opinions from folks who are familiar with this set up. Fuel line is 1/4" steel - blown clean New sediment bowl with strainer - clean, no debris visible New fuel...
