Newish snowblower but not sure what the cause of this is

First and foremost I would like to say hi to All as I am pretty new here. So My MTD snow blower is about 16 years old and still kicking fine. Bought it brand new and never did a service or even adjusted anything. I came across this used snow blower for a really good price so I jumped on it. Please dont look down on me lol as its a Snow joe but it was in mint condition and from what I understand its just a re-branded MTD. With at that being said. First thing I did was take of the belly pan after I brought her home. To see that the friction disc rubber had a couple flat spots. So I bought the new rubber. Removed the disc and took it apart. Put it back together and its gripping great. Does that mean that the cable was too loose or too tight?

If spots were rubbed flat on a rubber portion of a friction disc, that would have, in my opinion, been a cable to loose, thus allowing slippage and the ability to premature wear the rubber away.

But, It certainly may have been adjusted properly, and the previous owner just did not know how to operate the machine properly as well.

You are probably not privy to how it was operated or maintained, so can only assume what might have happened.

A friction disc should be brought into a drive plate (or visa versa) with a firm even amount of pressure, and that pressure maintained until it is released by the operator, for shifting gears, or at the end of the run or job.

Bring up the manual if you are not aware of how it should be, and that will tell you in detail on the proper adjustment for that unit.

It may simply have been driven against an immovable object (like a frozen snowbank) until forward motion stalled but without releasing the tractor drive hand lever. The friction wheel (connected to the tractor drive wheels) would stop turning but the disc (connected to engine PTO) would continue rotating and wear away a flat spot on the rubber.

If water gets on the disc then the friction wheel slips

LOL Ya I handed it over to my cousin. Its rusted pretty good. But now I am wondering if I made a mistake. This Snow Joe started first crank since I bought it two weeks ago. I go to try and start it just now and it made a loud bang like a gun almost and spark shot out the side. Followed by a small stream of smoke. I hope I am not in over my head here with this. SO now it wont start. I took the spark plug out to inspect and it looks horrible.

@dubzino,

I never came across a friction disc with a separate rubber which you can change out, all I have seen are bonded to the steel disc itself, but that material sure looks pretty flimsy for a friction disc rubber material.

Actually alot of them are like that from what I have seen. Can anyone chime in about the spark plug looking fouled up?

Maybe the float got stuck and let gasoline into the crankcase? Does the engine oil smell like gas?

Regarding that plug Ö. if that is oil as it looks like it is, that large pop might have been a terminal noise......
