Hi all--
I just picked up an older Yamaha 760 Waverunner (only has about 100 hrs on it), but it has a slight problem:
If it happens to sit for over 3 or 4 hours it becomes hard to start. The strange thing is that if I let it sit, it will immediately fire up after pressing the green "Start" button, then die about a second after it begins to run.
After it dies, it's hard to start. I have to keep pulling the choke lever in and out, and then it will finally fire. It's clear that the engine isn't getting enough gas, but I don't understand why it would start at first, then die. There must be some residual fuel in the float bowl. Once started, it runs great at any throttle setting. It'll restart right back up if I don't let it sit for too long.
Any ideas would be appreciated. Should I change the fuel filter, or adjust pop off pressure? What exactly is the pop off pressure anyway? I'm a pretty decent shadetree car mechanic, but have only worked on fuel injection cars. This is my first foray into the world of carburetors aside from lawn mowers.
Where is the fuel filter located on these things? Any pictures? Any manuals I can buy with regard to servicing? Thanks!
