RJL K. 61 and KRAFT .61

All parts interchange between Kraft .61 and RJL K.61. We found some older version back covers may shrink slightly over a period of 10+ years depending on fuel additives used by some manufacturers. This will cause the O-ring seal to be ineffective and cause erratic performance. Replace entire back cover if you have this problem.

K.61 Carburetors have been basically the same throughout production. The only change has been to the barrel and throttle arm. This latest design will fit all earlier versions.

Older Kraft carburetors used 3 different needle valves. The first Kraft carburetors used shiny nickel plated needles, black needles and needles with brass knobs. They all have different threads so be sure and order the right ones. Idle and main needles will match in color.
