I have a 1975 or 1976 Wizard eska tec. Does anyone know the correct oil mix and what spark plug to use? Also, where can I get a carb rebuild kit? This motor runs but will not stay running but a few mins then it shuts down but will crank right back. Also, does this model have an impeller to cool the shaft. Yes I know this is an air cooled eng. Thanks in advance for any help.
The fuel mixture on those is 24:1...and they are rated for TCW3 oil. You should be able to get a carburetor through Certified Parts Corporation (Google the name), as they have all the NOS and aftermarket stock for Eskas.
A lot of the Eskas use the Champion RJ12YC (updated plug) gapped at 0.030, but it depends on the HP of the powerhead. Can you post the HP so it can be figured out. The above was the plug used in my 7.5 HP Eska.
And yes, I believe that model has an impeller for cooling the lower leg.
