Re: changing VRO fuel pump on 85 120
when the motor turns over it revs up and down a couple rmp. It will be at 20 for a few sec then goto 17-18 then back up. One of the spark plugs I think in 1st cylinder ( if looking from stern to bow it's the top right cylinder) keeps turning blk. ive taken apart carb 1 & 3, i think i cleaned them. they were just done 2 months ago. its been running great since i got it back from shop, i started it every week, took it out 2 times and besides a spun hub it ran great. then i was out and when i would idle the motor would stall, then it got to the point where it wouldnt turn over anymore. i changed the plugs it runs now just does what i said above. last night i was running it and it revs really high for a few sec then stalls, did that a couple times then when it stayed on the bulb didnt feel hard i would squeeze it and it seemed like after a few pumps the motor would power up strong but then go back to what its been doing. someone mentioned the fuel recircuation valve, I havent tried that yet but i was going to see what happend and if that didnt work i was going to try a new pump. any suggestions? thanks!
