Hi Everyone. I own a KR2 with a 2.3l water-cooled VW without electric start. I found that once you have the priming cycle sorted out it really starts easy and it is not dangerous, no more than any other hand propped engine.
I agree with the rule "NEVER open the throttle more than a crack" for starting! Wish I could get my hands on a KR1, I just love little single seaters having recently acquired a Druine D.31 Turbulent. Fly safe, Rudi
