Newbie needs some helpie....

Hello.  I just purchased an incredible J3 cub with a 4-stroke 80.  The 
thing has been sitting for atleast a year and I think I need to pull the 
engine and run it on my test stand.  I dont have any 4-stroke experience.
Is there anyone in this forum that could give me some good 4-stroke tips?


Thanks alot in advance!!

Dan
