tohatsu 9.8 fixed
My 2 stroke 9.8 had been running a bit rough since I bought it last summer. Not wanting to idle and a bit lumpy. On researching it seemed like the carb was the place to head so I stripped it removing the jets/tubes etc and rubber bits and soaked it for a few hours in MEK then gave it a blow out with carb cleaner. I also took the little fuel pump apart , more out of curiosity as to what it looked like inside , but really glad I did as I found the source of the carb problems. A tiny screw that held a spring plate in had corroded badly and was a regular rust farm . Which im betting had been wreaking havoc in the carb. I cleaned it up temporarily till I source a new one with wire wool and now engine is idling better , but think last owner had obviously messed with the mixture screw and idle screw to compensate for the running problems caused by the blocked carb . So will need to have a look at those. Any one any advice? have adjusted the idle screw so it just idles without stalling but not sure what to do with the mixture screw.
