I wrote to Wren last week, but no answer yet are they on Holiday ?  :''

  Hi, I have been successfully running my Wren Jubilee for a while but during my start up yesterday it flamed out (blue smoke over 10.000 rpm) for a few seconds and then ignited again, on to a normal start and run/flight, all is setup to your factory settings with the exception of,
Pump start point 24, mine 30
pump power ignition kero 030, mine 34
Preheat fuel 40 mine 35,
I upped the Pump start point to 32 this morning, no smoke but the engine 'hovers' at 9.000 rpm and 60° for a while, before going on to a normal start, what do you suggest that I modify ?, it's 9° Celsius here at the moment, thanks Paul.


For information 9.000 rpm is the 'switchover point'.
