I love the smell of diesel fuel in the morning

While many don't seem to able to cope with the smell of burnt model diesel fuel, I thought I'd bring back some childhood memories today and make use of a new (and first) batch of diesel fuel that I mixed up. I'm sure those with a diesel heritage such as Ian will appreciate it. Unfortunately, nothing I ran today was English, but I guess they smell the same. Personally, I've had far too many years of exposure to petrochemicals and I no longer have any sense of smell to speak of, so I couldn't really take advantage of my experiment as I'd thought. My son assured me that I stank when I walked in the house, so I suppose it worked.
First try was my Aurora (Kumar) K150 from India. Had trouble getting fuel through due to congealed castor but it eventually fired up. Unfortunately, the contra-piston didn't want to return once I'd screwed it down to the point of sagging and left the adjusting screw floating loosely. I couldn't get it to back off, so performance wasn't optimal. Next was my Taipan Tyro 1.9cc. That thing just runs sweet as a button with a beautiful mellow note. Finally, my Silver Swallow 1.5 got a run. This was difficult to fire up but eventually it decided it may as well keep going and rewarded my efforts. This engine has a far harsher bark than my other diesels- I'm not really sure why that would be because they all have open radial exhaust ports.
Anyway my science experiment seemed to work, so I guess I'll have to find a plane to try one on. I think I'll give my old Mills P75 a run next as it was the first engine that I learned to start & run on my own.
For Ian's sake, I also have a FROG 1.49 Vibramatic, so I may give that a run too, although the crank pin appears to be badly worn. We'll see!

Rod.
