Greetings, and thanks to the fellows who responded to my earlier post about valve adjustment. I believe I've got the valves spot on, but now other problems arise, such as my carburetor. I've got the stock Keihin that hasn't been rebuilt, at least that I know of. I have had to deal with the hard starting, idling problems, etc. It usually is hard starting at first, but once it's good and warm it runs reasonably well, and starts again after I shut it down. I do have to fiddle with the throttle adjust handscrew a bit to get it to idle. Today I kicked it over and it eventually started on full choke and buzzed nicely at high RPMs, as it should. However when I go to half choke it dies. I've gotten it started from half choke a couple of times, but it dies when I shut the choke off all the way. Previously I would crank the throttle adjustment higher until it warmed up. Now it will not idle, and I can barely keep it running by twisting the throttle. Dies when I let go... SOOO, what's the opinions about rebuilding what I've got versus the Edelbrock pumper, Mikuni slide, and other carbs available? I'm getting old, and I'm really wanting to start it up and have it idle with minimal hassle (who doesn't I guess!). Help will be appreciated!
