With two 5 mm open-end probes, I suspect you may need to stock up on patience the night before...
Point taken, I will make a dual outlet nozzle for the leaf blower and bring a bag of tools in case I need to modify the injectors or anything else. The first test will have to be with a single propane bottle since I only have one in that size, later I will try to borrow a second one and do another test.

Thanks! About the braking, how about bolting down a hockey goal at the end of the track?

Awesome build , Excellent workmanship ,
Re, Injectors , I have not tried Rosscoes on my Thunderchine ( I wish I had ), You might consider crimping your copper tube down Rosscoe style, BUT crimp down on feeler gauges with smooth jaw pliers , I have found that this at least gives a calibrated orifice , and it is easier to ensure that multiple injectors are at least similar in their potential flow rates , you do however have to mutilate a set of feelers ,
Cutting the tube off with side cutters and then pinching them open a little produces a weird shaped hole ,
Just 2 cents , and good luck for the weekend ,
Thanks a lot! I could make a substitute for the feeler gauge from 1mm sheet metal which should give each injector an opening of 5-6mm2. I guess that the engine won´t turn self-starting after that but if it improves starting even a bit it would be worth the effort.
