1992 40 HP johnson will not idle or reach top speed in gear. I winterized the engine last winter, fogged and stabil. Started it up w/o a problem but will not stay running when I drop the throttle down. I was able to get in gear but the engine will only go half speed, 13' whaler not even planing.
To start the engine I have to give it about half throttle and choke the engine. I bring the throttle down to about a third and the engine will shut off if I press in the key choke the engine will stay on but it begins to race.
Replaced inline fuel filter
Put OMC tuner thru engine left if over night and ran the engine
sprayed carbs with carb cleaner.
Any quick fix? Is it the carbs or something else. Do I pull the carbs and have them rebuilt.
Thanks
Walt
