Well today we got the 074 bench run.The only semi-suitable prop I had around was a 7x4 wood zinger> The engine turned 11900 on it.
The compression is much improved and a quick touch with the little Sullivan half A starter lights it off. I used Cluttons Old English mix just to use it up, DDD 1/2 fuel was used also. We have a total now of a half hour on it as diesel.The super tight "catch" at the top of DC
is gone. My many thanks to Andy W for his advice and AJC for a great head. Its going into the Decathalon electric conversion to replace
the 061 norvel conversion. The plane had to be hand launched, this should now get it off the grass.
