Dude...you need to park that thing and get it right, b4 you got no boat for awhile.
Tear the carbs off, and go thru them. At same time, replace the ground cables/inspect them along with the red fat cables. Pull the lever assy out, to make sure the white button under the f/n/r/ is not stuck. Re-tighten all the clamps on everything, along with remov'n the fuel filter and clearing it out/replacing it from ones at ANY auto store (3 buks each)....then post back to forum.:cheers:
