you need to test in in the water...as loads will show signs of issues more clearly
sounds though that for now you are good to go.
if you need any help a simple(manual) carb cleaning is a simple thing to do...and will help.
btw you have just experienced one of the beatuies and PROS of old 2 strokes, they are anvils and simplicity at its best...dead reliable with dead simple maintenance.
Another update: I tested it in seawater this weekend. Amazingly, it continues to start pretty much right off the bat (fingers crossed), when I remember to put it in neutral. Went to a mooring ball about 1/2 of a mile, then did some shuttling of folks back and forth between two boats.
The push is not fierce - I expected more from a 4HP motor - but the motor sounds good (according to my more motor-savvy friend). Having the tank (6 gal metal, filled with 4 gal + oil) in the stern of the dinghy (Avon Redcrest) put the bow up quite a bit while towing the dinghy. When I shifted the tank to the bow, that seemed to balance it out, as it should, I suppose (the motor is ~50 lbs, the tank + gas is probably ~ 40lbs). I probably put too much gas in it to use it up this season, but I thought 1 gal in a 6 gal tank is too little for reliable fuel pickup.
A couple of questions for the dinghy experts - would you tow it with the motor up or down? More drag with motor down, I know, but it seemed less bouncy and more balanced. Or would you take the motor off except for very short hops? It's such a pain, though...
Also, when motoring in some 1+ foot chop, the bow of the Avon was getting lifted up and we were getting splashed a lot. It has a two-part home-made plywood bottom, with the bow part lifting up on a hinge). Would locking down the bow part of the bottom, e.g., with small bolt locks, help with that or make it worse?
Another friend suggested sticking a pool float noodle under the hard bottom to make it more V-shaped. I was thinking perhaps screwing a 2x2 to the bottom part of the bottom would help and make it more rigid. Thoughts?
