Getting closer getting the jetting right with the Husky. Took awhile longer to start, but when it did, it idled much better with the 55 pilot. HMF muffler also quite a bit quieter as well. No leaks, cooling system appears to be doing its job. Headers weren't glowing red, so I really think I am on the right track. Still a minor pop at idle when you rev the throttle. The remote fuel screw really came in handy -- it worked well enough with the 55, but with the screw 4.5 turns out. Considering it shouldn't be any more than 1.5-2.5 turns, I still need to go bigger on the pilot. Off to Scotty's for a range of 58-65 to keep experimenting. I also have fabricated a filter based on a foam/mesh filter from a VW race buggy. Will post pics of that when I am done. Finally, thinking I would develop the 610sm into some really neat engine, with a bit of hot-rodding, I stumbled upon this when surfing the web:
Some engineering geniuses have mated a Ducati 999 cylinder and head to a 610sm case (like what I have). They've switched from cam chain to belt, as well as a dry clutch!!! The transmission and case remains intact, so it is still a 6-speed, with the cable clutch. It loses the electric start, so rollers would have to be used. Staggering ingenuity!
