"Another Force Mystery" PART II

[ChalkBoy]

I have a '87 85 hp Force.<br /><br />I just pulled the plugs out....all 3 are caked with oil deposits. Wet ones too. I cleaned 'em up and torqued them down. <br /><br />I use fresh 93 oct. alcohol free gas with Penzoil Marine 2-cycle mix. I also used Penzoil Marine fuel system treatment the last two task fulls. <br /><br />My exhaust is very smokey at idle.<br /><br />Is it the oil/mix?<br />Is it the additives?<br />Is it the mixture setting on the carbs?<br /><br /> <br /><br />Thanks!

Clymers, "correct recirculation system operation is vitally important to efficient engine operation. If the system fails...it will result in"<br />1)poor low speed performance<br />2)poor acceleration<br />3)spark plug fouling<br />4)stalling or spitting at idle<br />5)excessive smoke upon acceleration<br />This may be the answer to your problems.<br />I'd do a though recirculation system check first thing. Have you messed with the carb.?<br />Did this problem occur after you had done some work on a component?

ChalkBoy after the gas treatment the carbs could be leaned out a bit and it would idle smoothly at a lower idle speed. Two ajustments. After the gas treatment clean or change the plugs. The exhaust is smokey from the additives and the mixture is gradually getting richer.
