Default .52 muffler woes

Well, due to a crash this last Saturday, my OS 52 four stroke sustained some damge. The muffler broke off, taking a little of the flange thats part of the head. The muffler itself has no damage. I ground the flange down because it was broke pretty ragged. There are enough threads left in the head for me to mount the muffler, and the jam nut tightens ok, but I wasn't able to grind the flange perfectly square and now I'm wondering if I'm getting a good seal. With the jam nut tightened all the way, I can see threads between the nut and the head. My question is this: If the muffler is very tight, will the fuel tank receive enough pressure if even a little exhaust is escaping through a somewhat poorly fitting muffler? Thanks in advance.

If there are no exhaust leaks, then you'll be OK. A small amount would also mean nothing. Run it and see.
