On my Craftsman snowblower there is no throttle control (cheap! cheap! cheap!), just an on-off switch, so it's either WOT/on or off. So, when it is shut down via the on-off switch it does so at WOT and sucks in a nice swig of raw, unburned fuel(you can smell it). Is all this washing off of oil from the cylinder wall something to worry about? It can't be good. Have any of you come up with a clever solution? There is no fuel shut off valve of course and no room for one unless the shields are removed and/or modified.
