Re: new old engine

That motor of yours is a 1976 Wizard. Carb Kit DI-52027 Eska Tec 642-22
Most likely a Tecumseh AV-520 powerhead. The AV-520 was used on outboard motors from 3 to 5.5hp
using your type number 642-222, from my small engine book, your

breaker point gap.....0.020 inch

Ignition timing (piston
position BTDC)........0.085 inch

I use 32:1 gasoline/oil ratio with a good grade TC-W3 marine oil in my Eskas and other vintage outboards.

Left click on "Small Engine Reference Center".
Left click on "Marine/Boat motors".
Left click on "Tecumseh Power Products"
Left click on "Tecumseh unit block models"
This should help you with point gaps and spark plugs.

Instead of Tecumseh Power products, you can click on Eska or Mcculloch (3-1/2 hp) or even Clinton for the lower units. They are pretty much all the same lower unit with a few exceptions.

This Database is good for other model outboards and small engines also, so save the link, username and password. It may come in handy someday.

Here is a Technician's Handbook for Tecumseh 2-cycle




Re: new old engine

Just found the model # plate. The model is ESK6613A67 and the serial is 67-350143. Yes I do need the point gap and spark plug gaps.
