Aggie94,
Well there are a FEW things to do.
NEw tank lines IN and OUT and a new rubber plug.
Pull the back plate off the engine and inspect for rust on the crank and around the bearings. IF ANY rust on the bearings replace em before running.( you can run em rusty but its HARD on the hole engine) the crank can be cleaned up.
New o rings under the carb and needle valve. flush fuel thru the needle valve by blowing in the exhaust line while the needle valve is out.
Reassemble, USE FRESH FUEL and good luck.
This is basically the same procedure for reviving one thats been lost post crash for prolonged period of time. Redid a brand spankin new one after a student lost it while "taxiing".
We were not watching and he got spunky and went for it. No one saw where he crashed and he quit trying to fly it once it was out of site. someone found it while looking for a different plane, two years later. It worked fine.
