Fuel injection systems
Roger B:
The two cylinder engine ran better with the improved delivery valve so I had a look at the horizontal engine. There was a fuel leak past the delivery valve with only 0.8 bar from the fuel feed pump.
I removed and dismantled the pump. There was a significant amount of rusty clag in the inlet port and delivery valve, probably due to the high moisture content of the cooking alcohol I used to use for trials. After lapping the delivery valve seat I cleaned it all in the ultrasonic bath and reassembled, replacing the delivery valve spring as there were signs of corrosion ::)
Roger B:
Seems to run well :) 1000-4000 rpm
Kim:
Wow! I'll say! That runs GREAT, Roger! :ThumbsUp: :popcorn:
You have a daunting number of experiments, time, and effort into this! What's your next step? Are you satisfied? Or is this still just one more step in your road toward perfection? :)

So now you have two engines running great with your system :praise2: :praise2:
I was almost thinking that you really had it all nailed until I realized that this is also running on petrol right now ....
Are all the rack bits for the diesel injector ?
