2002 Yamaha 70TLRA 70hp 2-stroke
I pulled this from a shed after sitting for over 4 years.
First thing I did was pull plugs and fill with WD-40, waited a few hours and turned crankshaft 180 degrees and did it again. While I waited, I removed the tank and put a new tank with fresh fuel (and SeaFoam) in it, removed the filter and and bowl plug, replaced the filter with a new one and pumped the bulb until fuel ran out of the drain on the bowl. I then replaced the bowl plugs and (on the advice of a long-time boater and mechanic) pumped the bulb until it was tight. I did this about 4 times with several hours in between cycles. The last time I pumped the bulb up tight, I removed the spark plugs and spun the motor with the starter for 2 or 3 seconds about 5 times spraying PB Blaster and WD-40 in the cylinders and carburetor throats as I turned engine. I then replaced the plugs and attempted to crank the motor.
It fired right up and ran well. After about 2 minutes, I noticed the middle carb had fuel coming out of a hole located at the top on the right hand side. (There are two holes side by side and this is the one on the left).
Can someone tell me what that hole is and a probable cause of the leak?
I am NOT a mechanic, but I suspect a float that is not rising with the fuel level either because it is stuck or has a hole in it.
