I just de-winterized the thing, put new plugs in and now it won't turn over unless I pull the pugs out then it turns over easily.  I am not a 2 stroke mechanic, is there a pressure relief valve not operating correctly?  It spins like a champ with no plugs, but once the plugs go in it seems to lockup.  Any suggestions are appreciated.
Thanks...
