<DIV id=post_message_2520218>My motor likes to run slushy at lower rpms, when running at idle the rpms rev up and down between 1-3000 rpm. I found a little red switch and started messing with it and was able to get the motor to idle smoothly around 1-1200 rpm. I was thrilled with that until i turned the motor off and could not get it cranked until i moved that little red switch the other direction. Once the switch was adjusted the motor ran great at high rpm but terrible at low rpms. My main questionis, what is the switch adjusting? The switch is located to the top left of my carbs (when facing the motor from the front). again this motor is a 100hp 1988 v4</DIV>

The red lever is manually operating your electric choke. It should be inline with the body of the choke for normal operation. To manually activate the choke, turn the lever 90 degrees to the housing. Sounds like you have a fuel/carb issue.

i was curious as to what it controlled

 

[GatorTamer]

do you think that a fuel pump issue could be the culprit?

Unlikely it's the fuel pump. Your carbs need cleaning. By turning the manual choke, you are adding fuel that your motor is being denied due to clogged jets. If you keep running it this way you could cause serious damage. 2 strokes don't like running lean.

+1

even it the motor has been converted to premix? Could the motor still run lean?
