My A4 runs fine in neutral (ie- responds to throttle the way you'd expect) however, when I drop it into gear (either fwd or rev) the rpm drops to idle and stays there no matter what you do with the throttle handle or the control arm at the carburetor. I've check the packing box and it seems to be adjusted correctly with a drip every so often. Someone suggested it wasn't a drive train problem but an engine problem, either timing or carb. I changed the plugs (sure enough the old ones were carboned up and I just put them in in July) but the new plugs didn't seem to make any difference. I put some vice grips (using a cloth) on the drive shaft between the engine and the stuffing box and when in neutral it takes about 4 ft lbs of effort to turn the shaft. I've pulled the boat (as you see in the avatar) and am ready to fix the problem - any suggestions?
