I have this old '74 V-4 115 HP engine I am trying to get running after sitting for 10 years. It starts and runs at a high idle when being backed into a lake on the trailer. I cannot slow the idle without killing the engine.
I am leaving a large gas slick on the water. From the best that I can tell, I am getting a pulsating slug of fuel pumped out of a port on the bottom of the air cleaner bracket. I took the engine off the boat, pulled off the carbs to clean them as I thought maybe the carb floats were sticking causing fuel to overflow. After taking the carbs apart, they did not look that bad on the inside.
I now can see that the hose that connects to this port goes to the engine block. I have two pictures showing the hose and where it attaches to the air cleaner. BTW... I do NOT have the air cleaner for this engine... never had it although I used this engine quite a bit over 10 years ago with no problems.
Can anyone tell me why or how this hose is pushing fuel out and how I can fix this excess fuel from overflowing through that port?
The first pic shows the port on the air cleaner bracket that is spitting fuel, and the second pic shows the hose in the middle that fits onto this port coming from the block (bottom carb removed).
Thx for the help...
