Hey guys,

Anyone good with small engines, like those found on a snowblower?

I have a 9HP Briggs & Stratton motor on my Craftsmen snowblower that I might have effed up. ;)

Condensed version of the story: Replaced the auger belt, felt good and decided to perform an oil change and spark plug swap (All using original parts that I ordered from Sears). Let the thing sit over night since I was tilting the snowblower in weird positions and decided it would be best to let the oil settle... Go to fire it up the next day and I hear a MASSIVE backfire explosion that rattled the windows and scared the dog (which was in doors).

Remove spark plug and notice that the grounding strap is damaged. This was a brand new spark plug (Which is the same size as the original).

Anyways long story short, I still have compression in the cylinder and I smell fuel (Although I need to confirm that the fuel is on the spark plug, haven't confirmed this yet) but I cannot get it to fire up. After this massive backfire, I got the thing started 4 times and it ran for like 5-10 minutes... So I don't think the misfire killed it.

Anyone good with small engine repairs and wants to help me diagnose my problem over some beer? :) I haven't pulled the head apart yet, trying to avoid that since I estimate it will put it out of commission for most of the winter...
