Hey everyone awesome site with good info! But still have a few questions.
I purchased my first boat earlier this year - 89 bayliner capri 1700 with a 85hp force(856X9G). Thing ran pretty good up until 2 weeks ago. It started having trouble starting and would fall on it's face while accelerating slowly. WOT and idle was smooth. I noticed fuel leaking from the middle carb bowl so did some research and bought a manual to help with gasket replacement and carb cleaning. When I got the carbs off I found that all 3 floats were not secured and were hanging with the pin halfway out. I proceeded to clean the carbs(with carb cleaner), replaced the bowl gaskets, and replaced all fuel lines.
I used the tutorial provided to reassemble, link the carbs, set floats, set air screw to 1 and a 1/4 turn, and set the timing at WOT to 30 degress. Took it to the lake last night and had it idling ok after about 10 minutes of trying to start it. But died about 30 seconds afted I put it in forward gear with it still on the trailer. I adjusted thd idle and gave it some throttle but it constantly died like it was getting too much fuel( could smell it from front seat). I tried to adjust the air screw with no success. I pulled the cover off the carbs and tried again and noticed fuel pouring from all 3 carbs(about a tablespoon) everytime I tried to start it.
So before I go any further I was hoping for some guidence since I'm no boat mechanic.
Compression was 120 on all cyl last time I checked, and has good spark.
What would cause so much fuel to pour out of the carbs?
It would also backfire with it in gear, is this caused by too much or too little fuel?
