I have a 1994 two cylinder Indy with EFI. My owners manual states that idle should be at around 1,900 RPM. I'm way below that.

How do I adjust the two carbs to assure that they're the same?

thanks,

david

well first off if you have EFI there arnt carbs to adjust.

a quick search came up with this topic

Well that's what I thought, but they sure look like carburetors to me. My son just bought the sled and I'm working on it for him. We didn't get an owners manual.

For sure it has EFI, so after reading the link you posted, I simply adjust a screw between the two fuel bodies?

a carb uses a slide. throttle bodies are on fuel-injected motors and use butterfly valves.
and yes, that screw sets how far open or clossed the butterfly valves are.

Thanks for the feedback. With the help of people responding to my messages, I was able to get my sons snowmobile running great. I really appreciate all the help.
