Re: Choking Problems - Yam. 90HP
Liam,<br />Are you sure you are operating the choke on your motor? I re-read your post and thought you may be using the fast idle/warm up lever to start the motor. To start my Yamaha 90 I lift the fast idle/warm up lever 50%, lift the choke switch and at the same time turn the ignition key. When the motor starts I release the choke switch momentarily, but if it starts to die, put the choke switch back on. Depending on the temperature I may have to do this two or three times until the motor will run smoothly at a fast idle. I normally let it run at 1500 to 2000 rpm for a few minutes as I get the gear ready, but then I reduce the warm up lever and the motor idles fine at 800 rpm. If your motor will not idle without the warm up lever, then you need to check the carburetion, timing and perform the routine service as outlined in the work shop manual. If you dont have a manual, I strongly recommend that you purchase the Yamaha service manual for your motor, it can save you a lot of money and down time.
