Default 1986 Moto 4 225 problems

     

Picked up an '86 225. *Flushed the tank, new carb, and new fuel switch on the tank. Starts up and idles like a champ. Problem is that it falls on its face when opening the throttle.

First thought was maybe the breaks we're *locked up (felt like it may have been grabbing).. Went trough all of that, and checks out. I adjusted the mixture needle to 2 1/4 turns from seated. Cleaned and checked the plug a few times, and it's black and sooty.Anyone know the correct setting for these carbs?

It seems to get worse as things get warmer. Since I discovered the spark plug boot is toast, going to go ahead and order a new coil. *I'm wondering if the coil is crapping out when it gets hot, causing the fouling *of the plug.

Clean the carb jets.
Remove the plug cap and cut the wire back about 1/4" and reinstall the cap.
Check and reset the float height in the carb after a complete cleaning and soaking.
