sounds like transmission problem it could be the lever but likely that the teeth on the gear for forward is strip and wont engage...take it to mechanic or take the crankcase transmission case off and play with the gear back and forth to see what its supposed to engage and look at the gear replace if needed...trust me its worth it to do it youself and its pretty easy..just takes some time prolly an 1.5hour!!
