runs on choke

My friend has a Artic Cat 500 2 cylinder with one Tillison carb. The engine will only run with the choke full on or a c... hair open, does anyone know why it won't run with the choke off? Thanx.

I had the same problem on my 1999 Yami triple. All 3 pilot jets in the carbs were plugged. Try cleaning the
pilot and main and see if that fixes it. Easy place to start.

Good luck

Re: runs on choke

The initial reply is right on! Sounds like fuel was left in the carb over the summer and it has gummed up the pilot jet. You will need some carb cleaner to clean it up. to do this you will need to take the carb off as well as the bottom float bowl. Spray cleaner through all holes!!! Good luck!!!
