It looks OK but reluctant to run
Followers of this series of posts are probably wondering what has happened to my build of Elmer’s #3 Open Column Engine. Well, whilst it looks to be ready to run it resolutely refuses to respond to the input of air. The crankshaft with inbuilt porting is clearly a critical item but despite making a replacement with extra care there is still no joy.
I have double checked all the porting and the reversing device but no real clues to its reluctance to perform. So, when time allows it will be a strip down and maybe a new bearing block – I will let you know !
