It is the ICU-L version that is supplied with the MVVS 16cc and 35cc, but equipped with a Vlach-type boot. I am not sure if one can repair that at home, but am quite sure it can be sent in for repair. The firm that fits the boots should be able enough I think. I think the Evolution ignitions are different in that they do not offer the L-version, which has no choke channel. The ones I have in stock now are -S versions (with choke) for L-version price, due to momentary MVVS stock shortage of L-ignitions.

The D10-WAT kit includes gaskets and both pump and regulator membranes, like needed for small carb maintenance jobs. IMHO, it should have a place in every field box of a gas engine pilot. Are you sure Horizon does not offer it? Any chainsaw repair shop will.
