Your saying mine is plugged or its intentionally blocked off? Seems to me that it's suppose to be. I poked around with a small wire and it dosnt feel like a blockage, it feels like it just bottoms out.

I have had in my hands, two of those jets in the last couple of weeks. Maybe mine are broke but after probing around with a small stiff wire, I opened up a hole and you can blow through it and the air comes out the small holes in the upper side of the jet.

Maybe I broke mine?

Okay, Ill dig around again when I go to rebuild the carb.

Any thoughts on the oil blowing out of the breather tube?

Blow by or a bad head gasket would be my guess.

When I did my head gaskets on mine I did about everything possible. Did you do anything with your breather cover. There's a reed valve ( I think that's what is called) and filter under that and also where the oil pressure sender screws into.

Even if rebuilding the carb makes it run right, I've got to stop the oil issue. I understand a little oil is normal but there is no way the amount I'm getting is normal.

If this thing is puking oil into the carb it will never run right. Just had a Vanguard with a bad head gasket do what yours is doing. As a test I removed the hose that goes from the crankcase vent to the filter and replaced it with a longer hose to get the oil from blowing into the intake. Ran it to a small pail. Then I was able to get it to run enough to determine what it's problem was.

Considering that you have replaced, head gaskets, ignition modules and rebuilt the carb multiple times you may want to consider looking for a replacement engine. Just my 2 cents.

No I havnt done anything with that breather assembly.

Yeah that's what Im thinking. I ran it yesterday and watched what was happening and it runs geat until the carb is overwhelmed with oil.

Ill try that today. What am I looking for to determine a head gasket issue? This tractor has only been run maybe two hours since the head gasket replacement and everything was torqued and retorqued to spec. What would make them blow that fast?

Ill start lookin around for another engine. Id prefer to just drop a brand new one in it but my wife may flip her lid. If Im going to go that route, I might as well tear the whole thing down and sandblast and paint it.

Do a compression test. When you did the head gaskets did you get the heads nice and flat? Not sure you need to re-torque the heads on the CH's. For what it's worth I have not re-torqued heads on Vanguards.

[BassBlaster]

Yes, assuming the 1/2" tempered glass I used is flat. I followed a link that someone sent me here. I sanded with 180 until everything was nice and flat and then polished them up with 220.
