troubleshooting
I am sure you have thought of this, but since you have gotten it started you obviously have spark, so fuel is the next most likely culprit. If you rebuild the carb, be careful, I once crushed a needle trying to put it back in. Scratch one carb. Had to buy a used one online.My first experience with my boat was the need to motor it from Boston's inner harbor to Winthrop. The lower shrouds were MIA when I bought the boat and I didn't want to chance sailing on just the uppers. Therefore I fired up the outboard, which I had worked on, but somehow avoided water pump replacement (it seemed to be indicating pretty well at the time). I swear, literally a minute after my Wife and I left the dock the stream of water indicating that the pump was pumping cooling the engine dropped to a trickle turning the hour long trip into a white knuckler. My Wife was less than thrilled that I bought a sailboat. Setting her adrift in Boston Harbor wasn't going to make a popular guy. Fortunately we completed the trip. Moral of the story? When in doubt rebuild the water pump...when not in doubt...rebuild it anyway and carry a spare just in case.Bob
