Carburettor initial set up after rebuild? (1971 K0 500 Four)
« on: February 02, 2016, 10:12:53 AM »
Anyone any advice on setting carbs up. I am anticipating investing in a balancer but for now have bench set using a small allen key so all 4 are the same. I have also set the mixture screws all at one turn out.

My plan is to get her going first then adjust the mixture screws before balancing but is there a methid of setting the mixture screws up without using a Colortune. There is something in the Honda setup manual that is downloadable from the site but seems there might be a page missing.

Any help/advice most welcome

Assuming all else is in order (all maint items.  jetting is correct for intake and exhaust setup, and a vacuum sync has been done) you can 'tune' each mixture screw setting by looking at plug color for that cylinder.
The goal is a light brown insulator tip.
