Engine will not start

I did some preventive maintenance to the engine and now it will not start. It is getting a spark and fuel. It seems to want to start, but just won't. HELPhttp://motorbicycling.com/images/smilies/pissed.gif
What I did was take it apart to replace all the studs. I was told to do this because the studs that come with the engine are pot metal and will break.

How do you know it is getting fuel? Check for airleaks, check plug gap, etc..

What was the preventive maintenance you did?

I second that, a little more info on what you did would help

Don't fix what ain't broke.

My vote is with norman. These engines are not so expensive that PM is worth the effort. IMO.. We all love them but we ain't married to them.
