Re: 1982 Mercury 500/50hp 4cyl
Thanks for your reply.
My idle is slightly rough, not even sure rough is the right word, it seems to have a slight miss while idling, its not jumping all over the place at all.
While in the ocean & increasing my throttle towards WOT the missing gets progressively more noticeable........& at times seems to be surging very slightly....when I bought this engine the gentleman said he had rebuilt the Carbs. & fuel pumps & had replaced the stator & some electrical items that he said Mercury was prone to have had problems with during these years.
While idling:
1. I disconnected each plug wire from the spark plug one at a time & each time it affected the idle...ran rough. which is good. also the spark looked great real strong on all plug wires.
2. I squeezed the bulb in the gas line and it had no effect on the engine idle & I sprayed a mixture of oil/gas into each Carb throat & it had no effect on idle....it did if I sprayed to much..........but that's normal.
Having one carb per 2cyl's.....if I disconnect 2 plug wires, at idle should this engine beable to run on 2cyl's ?
Thanks
