“Insensitive” Idle Mixture Fuel Screws?

I often field this common complaint: 

“I’ve noticed that turning the idle mixture screws nets different results on each of the individual carbs on my Honda GL1000:

  • #1 will kill the motor if turned all the way in
  • #3 has NO EFFECT on engine speed regardless of where it is set
  • #2 has what might be considered a “normal” effect
  • #4 has only a very slight effect if any at all

What does this mean????? I’m a bit confused?  Help please!!!!”

I have personally benefited from crop subsidies and understand the benefit of the emerging ethanol (made from corn) fuel market to corn farmers. I am sympathetic to their issues.

Viton Proof?

All of the ordinary round orings and many other components in Randakk’s Master Carb Overhaul Kits® are made of genuine Viton®. In fact, every oring we’ve ever shipped has been made of Viton®! Plus – through proprietary molds and other tooling assets, we make many other Viton® components ourselves via our own exclusive manufacturing arrangements.  In other cases, we have direct sourcing arrangements from superior production partners that by-pass normal trade distribution channels.

More On Aftermarket Fuel Filters

Fuel filters are not included in Randakk Master Carb Kits. But, it would be a crime to redo your carbs and not take prudent measures to ensure a pure fuel supply! We recommend the OEM Honda filter as a high quality replacement unit for owners concerned about originality..

For others – we offer the Randakk High Performance Fuel Filter with sizes to fit virtually any carbureted motorcycle. Details here.
