    I am sure that something is wrong with my carb. Have any of you encountered this problem. I went to crank on it this evening and it started blowing white smoke and spitting and sputtering. I looked on the front castor and it was covered in an oily substance. I then checked my oil and yup...gas mixed with oil:(..maybe i can drain it and use it for my weed eaters :D..anyway..anyone have experience with this problem?

    Throw out your ruined oil and get a new inlet needle/seat and
    check your float. If the old float has fuel in it, get a new one.

    sounds as simple as a broken diaphragm in your fuel pump.

    loosen your fuel pump, crank it over and see if gas squirts from the side that faces the block.

    i wouldn't stress.

    i've seen floats stick and load up blocks also.

    i wouldn't use that oily gas in my 2-stroke equipment either.

    Since they both dealt with the same topic, I merged the two threads and kept it here in the Mechanic & Repair forum since it's repairs we're dealing with. :)

    needle and seat worn out....waiting on the part also had some trash in the bowel as well...drained the mower and tilted it on its side to make sure all gas was out. I should have it back together by friday:p

    Remember to change that oil! It's got all that gas in there and isn't worth a damm now. Hate to see you fix the problem - only to ruin the engine later because of the oil!
