im trying to get this motor to run right after it sat outside on a boat for 6 years . it wont idle without the choke being on halfway. after checking compression it turned out to be 115 on both cylinders . a buddy came by and said that the upper cyl. wasnt firing or was weak due to the temp of the plug as compared to the other spark plug. im trying a new set of plugs tommorrow. im thinking if i get it to the lake i will run it for a good legnth of time and maybe it will loosen up or free up a stuck ring or something. any suggestions or advice? thanks
