Guys: I have a '99 Yamaha 4 stroke, Hi-Thrust, Electric Start (Thank GOD FOR THAT!)<br /><br />I have to spin and spin and spin and try and try and try to get her running. Without Electric start, I'm not sure anyone has the arm power to do it by pulling.<br /><br />Once warm and once she "catches" and idles fast, all is well. <br /><br />Is it time for a good carb cleaning? <br /><br /> BTW, the Fuel Pump is New (upgraded with water cooled model) and the fuel line and bulb are new too.

Yes, time to re-built or clean up. 1hr easy job.
