I installed a FCR Wr450 carb on my Wr426. Now I can't tell any difference with trying to adjust the fuel screw in any directions, knowing there would be subtle changes. I have adjust the fuel screw down all the way and opened it up to 2 1/2 turns out and no difference. Just the stagger from running low idle.
I have listened to the throttle blip is crisp and on point at 1 3/4 turns. 2 turns out the throttle hangs a bit while riding. Again, trying to adjust this fuel screw makes no difference idling. No stagger turning it in or running faster turning it out.
I have watched a few videos and I don't even come close to the adjustments in these videos. Thoughts?
