Thanks very much for the expeditious advice and the compliments, they are all very much appreciated.
Here goes with some answers to the posted questions…
..Carbs were all disassembled, cleaned, and reassembled with new kits. Bear in mind that this was my first go at it. I did nothing with the Welch plugs…guess I am about to learn about them…
..
I ran circular manifolds for air and gas around my restored tank, and "T"eed of branches for each of the three motors. Manifolds gave a more equal supply/pressue drop for the fuel and air to each motor. I am awaiting a tach as mentioned to verify all will run concurrently at max rpm without being starve for gas. They all ran together briefly at a pretty high speed in my test pond. Don’t think manifolding these three little guys will be an issue.
..Gas was not 100% fresh. I will use what I have left in my Echo string trimmer (16:1) and fill the tank fresh before any more trials.
..I was hoping to burn the new rings in under load for a few hours to recheck compression. I never did get a new reliable compression gauge…will now just a little sooner than I had intended.
..Indeed of note, Chris, that all three are hard starters and poor or "non"idlers. It would be great if there were one common problem, but more likely multiple issues. Seems like from what I read, good idling is the toughest thing to achieve. Ironically, two of the motors started up and idled quite nicely in a barrel right after I bought them, and then I started dissecting.
..Even with all new ignition parts (except some coils were ok), the spark seemed just "OK". Again, hoping for no good reason that the spark would improve with some run time.
..Very interesting suggestion, Mumbles. I will check this out. Any good way of identifying the problem? Mic measurements?
Again, thanks for the help. I have enough to keep me busy for a while again now.
Another couple of closer pictures. Aesthetics are at least an accomplishment, mechanicals will continue in progress. I wound up buying a running CD-11 that I am only going to spruce up, and I found another beat up old CD-10 that runs, but plan to use it as parts. Buying stuff at bargain basement prices is addicting. I wonder if there is a 12 step program for this?
Remain open to more input. I may just remove a carb and hire someone with the proper expertise to repair and see if any of the motors come around with a known, properly rebuild carburetor.
WIll update when I finally figure out what issue(s) were.
