I have for you a solution, which has worked amazingly well for us. I have finally succeeded in repairing our dinghy engine in a manner which guarantees that there will be no further need for repair. What follows is a step by step procedure:
This is a photo of our dinghy engine as it sets on the stern of our boat. I used a special 'personality' filter to take this photo.
Step 1: Remove the cover and remove the carburetor.
(Being careful not to lose anything overboard - I'm speaking from experience here.)
Step 2: Disassemble carburetor.
This is a closeup photo of the carburetor with the float valve, the idle jet and the high speed jet removed. They are soaking in carburetor cleaner as this photo was taken.
Step 3. Consult instructions.
This is an exploded diagram of my carburetor excerpted (fun word, huh?) from my parts manual. My carburetor doesn't look a thing like the exploded diagram. I thought it should and could only think of one solution.
Step 5. Gather needed parts.
I looked in the Yellow Pages and found "Explosives 'R' Us. They're not difficult to locate. They are all over the country, due to a less than adequate enforcement of their No Smoking Policy.
Step 6. Install parts.
After carefully installing my purchase in the space formerly occupied by the carburetor, I lit the fuse and stepped back.
Step 7. Check the effectiveness of your repair.
I doubt that the ringing in my ears will ever stop, but I believe this photo will attest to the permanency of my dinghy repair solution.
Step 8. Clean up.
I still have some clean up, glass work, and some new stanchions to install, but I'll never have to work on that devil of a dinghy engine again - and that's a relief.
