2072 getting gas in oil
 

Hey guys,
My 2072 is getting gas in the oil and when I removed the air cleaner I noticed oil on top of the carb.What's That about? Is it a bad fuel pump or bad needle and seat in the carb? Thanks.

Sounds like it is time for a new fuel pump and maybe a breather valve too.

Check the carb, I had the same issue and the carb I had just rebuilt 4 months ago was full of brown gel-like beads of crud from moisture in the fuel. But it could also be the needle valve is not sealing. If that's not it maybe the fuel pump.

Ok, I figure the same thing, thanks guys.

Am I better to get a carb off a kt17 or rebuild this one? It's a walbro.

Nick, you can also put a #26 carb on it.

:IH Trusted Hand: I second that motion!

I think the consensus is; ditch the Walbro. :beerchug:

Thanks Allen, what about the linkages?

Probably have to swap the throttle shafts.

Ok thanks.

On guys,
I changed the needle in the carb and changed the oil, got to replace a fuel line, but let's see what happens.

Keep us posted on your progress.

Will do lew.

Nick

Did you replace the fuel pump?

Not yet sam, I will be because it is still mixing.:bash2:

Nick bypass the pump for now and see what happens.

Thanks Todd, Sam told me the same thing , will do.:beer2:

Hey guys,
We got the new fuel pump installed, also installed new intake manifold gaskets, and we put the carb back on, the oil looks good and I started it up and let it run then shut it off and checked it and it still looked good, hopefully the problem is fixed.

Sounds good. I'd run it for a while and do an oil and filter change just to be sure you got all the gas out of it. :beerchug:

the oil was changed already before gas got in and the filter is brand new.

Nick, did you change the filter and oil after you put the new pump on and test ran it?

No, this is the 3rd time we have changed the oil, the filter is new which we put on after we bought the tractor. We did not change it again because the oil is clean and does not look over filled or smell of gas.

Just my 2 cents, but an oil filter and a couple quarts of oil are cheap compared to the cost of a Mag. Your $$$ your tractor do as you wish. :beatdeadhorse:

I totally agree with Sam, Nick. Easier/cheaper to change oil and filter rather than rebuild or repower.....................:bigthink:

What they said!!!

Ok guys I get it, I just drained it out and am flushing it out, will refill it and then see what happens.

Don't forget to change the filter,make sure all the oil is out by looking in the drain hole NYUCK NYUCK

Just picked up a new filter for it, gonna install it.

Glad to hear you are doing it right. Something for you to remember as you grow older "You can always afford to do it right the second time" I was taught that many years ago. :beerchug:

Thanks Sam, I agree.:beerchug: and it's all done and seems to be ok, I hope.

Better to be taught that lesson that learn it the hard way :bash:

Hey guys, I'm having the EXACT same problem! Oil smells like gas and the top of the carb/bottom of the air filter is covered in oil. I priced a fuel pump at $80 at my local cub dealer... Runs bad and hard to start also... New fuel pump or bypass and what else?

I'd bypass the pump to test that it is in fact the pump and not the carb. Drain the oil refill and replace the oil filter.

Just Googled the Kohler part number for the pump (52-559-03-S) they are priced all over the place looks like from $35.00 and up.

Sam, when I do get it running, a very small amount of oil will come up through the small tube that is under the air filter... Breather tube?

I think you will get that if the oil level is too high, which, if you got gas leaking into the oil, it's going to be higher than normal because of the gas.

Yes, that is the breather tube. When the oil gets thin with fuel it will puke more oil. Get the problem fixed first, then see how it acts. It's normal for a small amount of oil to come into the housing from the tube, but minimal.

Thank you all for your prompt replies! Thanks Johnathon, I really appreciate your reply... BTW, I really enjoy some of your replies to the knowledge challenged!!

What ever you do, don't continue to run it with gas diluted oil or it will go bang and you'll join the see through block club. :beerchug:

Yeah, the 2072 was taking a break from lawn mowing duties and the other day I wanted to get her out to stretch her legs... She really didn't want to! :BB&YS: She's in the shop now with the hood up and ready to get a fuel pump bypass. Just have to let my back rest a day or two :bash2: so I can make the diagnosis! :biggrin2: :beerchug:
