Things are getting better
Since my last post, I have fitted new dissy cap and rotor button, so all ignition components except the coil are new.
I took the carb off and cleaned it inside and out, fitted new gaskets and o-rings throughout and put it all back together. Some of the o-rings were a bit gummed up, one or two gaskets looked damaged.
I also got a timing light and found ignition was way advanced, so reset at 2 ATDC as per the manual.
Engine certainly seems smoother now, and far less 'popping' at idle. Drives well too, but power seems to come in at higher revs than before. Still not sure I am getting the best out of it.
Will try a longer drive, get it properly hot and reset inlet tappets and mixture. Then the exhaust valves will be all that's left and I will HAVE to deal with them.
