250 trail boss

[Mmcswain]

Hey guys, I'm new to the ATV world but I purchased a 250 trail boss a few days ago for next to nothing for our property. I got it home and it starts easily but started blowing a ton of white smoke. Today I filled it up with a 50:1 mix of 93 octane and tcw3 oil and now it won't run. I started it up, it ran for a couple of minutes then died and now will not start. Does anyone have any ideas? I don't know the year, but it does have a 7 digit vin.

It probably has a fowled plug, if it is a 2 stroke it should have oil injection and not require a premix in the fuel.

Does the injection system not work? Just trying to get idea as to why you premixed.

The guy I bought if from disconnected the oil pump and was pre mixing it. It is something that I want to reconnect. Would a fouled plug cause all the smoking or should I tear the top end apart?

First thing to do is to do a compression check on it.
