My engine numbers are: 217.59310 and I was wondering what year it is and what the oil/fuel mix is too. <br />We took it out to the lake for a test with the mix I use for my weedwhacker and it ran rough. It leaks fuel out of the carb drain plunger too. So I ordered a new plunger seal/washer from Sears, along with two prop shear pin kits too. When I got the motor it hadn't been run in 2 years so I replaced all the hoses, the fuel filter and installed a new spark plug. I also rinsed out the gas tank and petcock with carb cleaner. I took apart the carb and cleaned it with spray carb cleaner too. I was very happy it started and ran...OK. <br /><br />Thanks in advance for your time,<br /><br />Mike
