Just a heads up. If you watch this video and read the comments, keep an eye out for the next video because boost referencing the top of the carburetor and side gapping the spark plug was the ticket.
4:07 lol. Yeah I prefer antileg on all my saws but it doesn’t matter much on the string trimmer’s.😂 That would be something to see! What a fun project!
I know this is just a fun project but don’t discount the information you’re gathering. I’ve actually thought about practical forced air induction on a chainsaw years ago when we lived at almost 4,000 feet and I did a lot of chainsaw work above 6,500 foot elevation. I messed around with Tesla turbines for fun just to see what they can do and they actually work pretty well. My idea was a a belt drive Tesla turbine for altitude compensation and possibly even more power. When I first read about the 500i my first thought was a Tesla turbine. I’m thinking a Tesla turbine might actually be small and lightweight enough that it could work for a daily use felling saw and possibly last longer than a ported saw. Or maybe a lightly ported 261 with a Tesla turbine that puts out 8 or 10 hp and just rebuild it twice a year. Our 261 is a good 5lbs lighter than our 500i.
Also don't forget to go after the unlimited coil for the 661 it should free you up to leverage the heck out of the high end and will help sustain the higher torque at higher cut speeds - look at dze coils - great work! Keep going!
