| My os 61wc has some unusual idle characteristics that I hope someone can help me with.
With the engine started, I can set my trim for a nice fast and smooth(clutch not engaging though) idle. The engine will purr along for say 10-15 sec and then as if someone flipped a switch, it drops into a very low speed, chugging, almost gonna die idle. The engine will chug along for 5-10 sec and then again like flipping a switch, it goes back to the fast smooth idle. This will continue until I either rev up and take off or it dies.
The motor is new (third gal). I have the main needle tuned so that while hovering it 2 stokes about 75% of the time with intermitent 4 cycling. I'm using Wildcat 15%. I am sure that the motor has never seen even 75% throttle nor been run lean.
I'd bet its a simple fix, but this is my first experience with a three needle carb, and I don't want to get it too far out of whack with my still ignorant fiddling.
Thanks |
