Please read the reply I made to the post right before this one. I answered the question I had concerning two diff carbs being tested. I did test the same carb on the same day. The two carbs were 1.5 years apart, but only 20 degrees apart. The results just seem strange to me. However:
A 20* temp swing for a carb is huge. Density altitude changes and more O2 to burn at cooler temps. A 20* swing would require a jet change in my car to maintain proper AFR at the track. Air velocity is different in the 650 and 750 unless the venturi are the same size, also booster type could be different, straight/downleg/annular. Was the fuel curve base lined to be the same on both carbs?
I'm not knocking you, these are just some of the variables that effect testing.
How can I get a single cylinder, for example a 20hp lawn tractor engine on a dyno? I have no idea where to find a dyno for a single cylinder?
I suggested single cylinder to prove your idea works and warrants patent approval. I'm not a dyno expert. I wish you the best.
Before and after runs were made in both Oct 2016, and Jan 18. Two separate before and afters. My question is how could the dyno say I am pulling more then than now when the engine clearly has more power now.
I have emailed the dyno owner, who is probably the only one who could answer this question, but I agree, if there is a way to dyno a single cylinder engine. I don't know how to do that but I do have a 20hp lawn tractor with a Kohler engine if you know how I can find a single cylinder engine dyno.
Thanks
