Welcome to RCNT!
First question, how much usuage has the engine had? If it's well used, hot starts can be a pain due to low compression.
Many things can cause your problem,we are going to need more specifics on how it runs when it's running, how much smoke,what temps are,what sounds it makes. The more info the better we can help. Check back and let us know, we will help you figure it out.
Also note, there is a Savage specific forum for Savage questions and lots of other specific forums. Check them out, posting in the right forum will help get more and faster responses.
