White smoke from crankcase vent???

55-60 years ago there was little traffic on the highways.
Also the police knew a lot of the "locals" and cut us some slack.
They were young too, not that long ago.
Don't get me wrong, if we did stuff that was more than lighting up the tires,
like driving while drinking under age/driving drunk, we got in trouble.
It was a good time to grow up, the air was dirty, but sex was clean.
Gas was .$0.17 a gallon and I made $0.65 an hour.

Woodstock wouldn't happen for 8 years and the beetles were bugs in the garden.
No Crack in my system just grease under my finger nails.
I wouldn't mind going back if it could be done.


Now i need to blow the whistle on myself, as I have run this train is way off the track.
My apologies ( till next time)

Well, there isn't any issue with that. Nothing wrong with talking about how things used to be, I wasn't alive at that time but have heard so much about it that I wish I was.

Going back to the topic, I think I'm gonna do the oil change tonight rather than Saturday because I have more time than i thought. We'll see what happens

Okay progress update:

Oil has been changed, about 1.25 quarts of this stuff

Old oil was a bit darker than it seemed inside the engine (although that bucket was already pretty dirty )

Results:

So I believe there is gas getting into the oil. When I shut the machine down last Saturday the fuel line was full of gas (it's a clear line) but today when I went to start it it was mostly empty. After the oil change I shut the valve and let it run itself out of gas, but there must be something wrong with my fuel system.

Speaking of fuel system, it has a very tight flow. The carb is a new Chinesey off-brand, and it seems to function fine when running. It seems to run a bit rich, unless that's just my bad tuning. Gas only flows through the fuel line if the needle/seat is open, so once it fills the gas stops flowing through the line. Now it works fine when running, but I feel like that isn't normal.

Okay and the most important part, once at running temperature, unfortunately the white cloud came back. Someone did say I may have to run it for a bit to let everything evaporate, though, so that may be why. I stuck my face up under the breather while it was running and it clearly doesn't smell like anything, leading me to believe it is most likely steam.

Any thoughts/info or some help with the fuel system?

Do you shut the gas off when you shut the engine off and see if your fuel level in your tank drops any? And the oil level magically rises before you fire it up again?

[Cubcadet_107]

I always shut the gas off once I turn off the engine (except this time when I shut the gas off and let the engine run out of it), gas leaks slowly from the valve on top of the fuel bowl, only when the valve is closed though. The tank may slowly drop in fuel level because of this leak, but the gas is just exiting the fuel system entirely and dripping on the ground. Gas will not flow in the line when the valve is closed, so that works properly.

The oil level was previously right about at the max fill line, and when I noticed the absence of fuel in the line, I checked the dipstick. I noticed that there was a very slight amount of clear liquid that seemed thinner than the oil below, bringing the level to just above the max fill line. When I drained the oil into the bucket, it seemed that a thin layer of thinner liquid settled on top of the oil too.

Nope, can't have that. Gotta get the fuel system to shut off completely, every time. I can't comment on the carb or tuning except the way I do it. Warm the engine, then run it full throttle no load, turn the main mixture screw in until it starts to drop RPM, then turn about 1/2 back rich(out).

OBTW, best to use non-Eth gas as the Ethanol is hydroscopic(draws water from the humidity in the air).

Leaking around the "T" handle on the valve??

Tighten the packing nut on the valve shaft a bit.

[Cubcadet_107]

Yes, that is where it leaks, only when the valve is shut off though.

Unfortunately tightening the nut won't help, the reason it leaks is because when the valve is closed, I can wiggle it around inside the packing nut because it's worn out.

Not to mention the fact that whoever used that gas tank and fuel bowl before me stripped that nut completely

Come to think of it, I don't think that leak is enough to get gas into my crankcase, right? All it does is slowly drip onto the ground

[darkminion_17]

The gas will leak out the carb and into the air filter before it gets in the engine if the needle valve is stuck open.

What's a new valve bulb assl'y?
$15??
No brainer.
