I have an MVVS 1.50 and i crashed it. The muffler bolt's striped out and i want to re weld them. However the engine is greasier than McDonald's. How do i clean it? One dilemma is that the outside part of the engine is all one piece and i can't take it apart in sections. The casing of the engine is all one piece and it need's to be cleaned. I have a solvent tank at work, can I use that?

Try some contact/brake cleaner from the auto parts store. It doesn't leave any oil behind after spraying. It's the best oil remover I have found and it's cheap too.

I also have a muffler extension type thing that survived the crash, i was wondering if it is a good idea to just weld that back on to the side of the engine and just not deal with the re tapping and stuff.

I wouldn't! You might warp the crankcase with the heat of welding. That would be real bad news. You might end up with more problems than you started with! my 2 cents worth.
