    ford 172 engine

    as stated above...it is a large volume electric fan. but thanx I adjusted the timing back just a touch and it smoothed out on the vac gauge. seems to run cooler so far. Thanx for the suggest Den N Ms

    No true shroud. The self contained fan has its own little shroud...but the radiator itself is open.

    ford 172 engine

    Ill check thermostat. it has had new flush and coolant...radiator looks good. I put a huge new electric fan on because it was not cooling...that helped a lot and has not heated up until now. but it cools quickly right after the heavy load...so I think thermostat is working and radiator is...

    ford 172 engine

    thanx for the advice markct. Ill look into that. for the others...go buy yourself a compound vac meter. you can tell a lot from your vacuum pressure....and manipulating that pressure with carb settings and timing... that's how they would do a proper tune of racing engines in Europe before...

    ford 172 engine

    Back again with another engine question...remember this is on a 24" train...not a tractor !! It is up over 100 these days and one of my old girls gets her temp up on one of our steeper hills. It doesn't cross 220 deg(by gauge) but nudges up there.. then drops after the grade. while up at...

    thanx I will check that. mabe even add fuel dryer somehow or a drain like in aircraft to check low point for water. ill look into our bulk tank also...see what I can do there. I have one running quite well but this other has always acted like this. and been worse this last week or so.

    Ford 172 sputter

    I am having a persistent problem with these 172 engines. at idle they give occasional sputters. Is this just normal for the 172? Or what is causing this? I have rebuilt the distributor, new coil, new resistor, new plugs, I feel the carb is set properly. these are in our trains so get long hours...

    ford 172 carb

    I put the seat in very tight but not slip the screwdriver. I have lowered the float twice. and today it still leaked overnight into the intake.

    new seat...new gasket

    ford 172 carb

    float is not leaking that I can tell. It is new viton tipped needle and seat that I checked for damage or debris. I adjusted the float about 1/16th inch lower and ran it, then left over night. it leaked into the intake tube again. should I lower float another 1/16th?

    ford 172 carb

    Well I take the air inlet tube off today and it has fuel in it. with new float needle I guess somehow the float is too high? it never puts enough pressure on needle to fully close?
