It's a 1975 1150 straight 6, had it running many times, leaks gas every time. The throttle is now adjusted right, and it engages forward and rev. Runs good other then gas leaking out the bowl, somewhere along the bottom and spurting at me out the float chamber overflow port all from carb 3. It had sat a couple of years, so I rebuilt the carbs the other day. It was sad what I found and it needed to be done. Carb 2 had sand in the float chamber, and someone had used red gasket goo on every screw and cap. Of the three boat shops around all were out of floats, one had three carb kits. The throttle linkages needed to be repaired, the loops were braking and I tried to get them as close to origanal shape as possible.
Got it all back together and on it ,started up good, ran at a higher idle. The idle mixture screws were #1-1 1/2 turns, #2 - 2 1/2 turns,and #3- 3/4 turn. #2 being the one with sand in it and #3 being the leaker. I evened them out abit and it sounded good, just a little tiny bit of a gas leak from #3. Seamed like a lot of progress and got to working on other things.
Today started it up and just could not run it with the gas leaks. Something I noticed last week was I don't get a firm gas line bulb any more after a couple squeazes and today when I shut it down it made a bit of white smoke rather then the normal blue.
The three shops around me, the one an hour north sells some parts for it, but will not work on the older mercurys. The second shop is 1 1/2 hours south, both Mercury dealers. He has parts and seams like my only option if I can't resolve this. The third shop, over a town (close) had no parts, no advise, have to see it , and seamed like a fella that would make a part fit if needed.
Sorry for the long post, am I looking at fuel pump pressure problem, floats still need changing, they were not saturated, but the sand did a number on #2's. Any help is appreciated
