Tuned and Synch'ed
Greetings folks, Steve/Fossil here again. I think last time I was here it was while I was looking for info on upgrades for my Griso. The time before, needing help bleeding the brakes on one of my T3s (if my memory serves me?) Anyway, I'm back, finally, on the newest-to-me T3. I bought it 1 1/2 years ago and feverishly worked on it until I got to the point where I was about to wind up the project needing only the paint on the tank and side panels and really just a tune-up and start it up for a ride. Well, I got side tracked and haven't done anything on it for months until a few days ago when I decided to "Just Do It". I could wrap it up in no time and be riding. Or so I thought! I got the tank painted and am working on the side panels and did a quick valve adjustment and points setting. The carbs had already had a good cleaning a few months ago ( with only race gas in them since). So, the big moment. I cranked it up expecting a great-running machine, and got anything but. Running on only the left cylinder with the other jumping in now and then. I re checked the points, dropped the bowl off the left carb (clean), reset the air screws, got the carbs synced as close as I could by ear, checked the throttle cable free play, checked both coils, made sure the cables were seated in the adjusters, etc.. Then, for some reason the left started joining the party more often, but still part time, until the revs come up. Then it stumbles a bit but once over that range it revved as if nothing was wrong. I felt like I was making progress, then it started revving on its own! I took it for a couple short test runs a mile down the road and when I would pull in to turn around the engine would idle down, as expected, then just start to rev. Finally, at about 5,000 rpm, I had to hit the switch and shut it off. Craziest thing I've ever seen. And it has done it several times. To say the least, it makes for an interesting ride. Anybody ever had this happen? Reminded me of the Husqvarnas and some other bikes I raced in the '70s, when they started running out of gas, some of them would start leaning out and act like that. Thanks for any help. I am so excited to finally have gotten back on this project and basically finish it, and am ready to ride it. Foss
