Hello all,
First post here. Ive searched this to hell and i havent found anything exactly like my situation. I just bought a 1986 stingray ss 175 with a 3.7 merc 470. The kid who sold it to me told me he was out on the water and it just stopped running and was unable to get it running again. He proceeded to have the carb rebuilt, and change the plugs/wires. I got it running. First thing i did was check for spark at the distributor. I had it but i have nothing at the plugs so new points condensor coil and cap and rotor. i then corrected the firing order on the cap as they had it in the wrong order... next was timing i turned the crank until the hash mark on top of the balancer was at the 0 degree stamp on the block, i pulled the cap off the distributor and had to move the wires over one spot to get the rotor inline with cylinder 1 then i Loosened the distributor and turned it while i pour gas down the carb and my friend cranked it. it would fired a bit and not run. after i got it to where it sounded decent i pulled the fuel supply line off of the fuel pump and turned it towards the sky so i could pour fuel from a squirt bgottle directly into the carb (disconnected the fuel pump obviously) and it ran! now its time to put it all back together. poured some fuel down the carb and it would run for a few seconds, i was hoping it would begin to suck fuel and prime the system but no such luck. to the marina i went to get an inline priming bulb. primed the system (new water seperator/filter included) and vua la it ran. sounded good as well. i only ran it for 3 or 4 minutes. impellor worked even though im going to change it anyway but overall everything seemed good and it revved up fine. i turned it off and restarted it to see if it would re start and it did instantly each time. fast forward to the next day. i have to reprime the entire system. i was a bit concerned so instead of taking it directly on the water for a first run i decided to hook it up to the ear muffs. i poured gas the carb to get it started and it ran ok but then it stalled at idle after a few minutes id have to prime it to get it running aganin and it would only stay running if i applied moderate throttle. Think i have a fuel pump issue?
