I'm trying to get my newly acquired TR7R running after what I believe to be a 10 year rest. I changed all the fluids and was thrilled that I actually got it started. It certainly doesn't run smoothly. I'll list out some of the factors and maybe you can offer some advice.
Coils
The previous owner put new ignition coils in. The resistance reading on the coils is (the number in parenthesis is the setting for the ohm meter):
Right side:
Primary 3.8 (200)
Secondary 5.8 (200k)
Left side:
Primary 3.9 (200)
Secondary 6.1 (200k)
Plugs
The left side plug looks pretty normal. The right side plug is quite a bit more sooty (see attached). I suppose this would indicate a rich mixture, but why only one side (single carb)? I put in new plugs and they did the same thing.
Carb
I don't have a lot of experience adjusting carbs, but I did notice something. The air pilot screw is loose and I think it's working it's way out when the bike is running. The throttle screw seems similar. Am I missing a spring inside both of those, or an o-ring. I'll consult the diagram for my carb. When I had it running, I did adjust both of these to various settings and there wasn't anything that made a profound difference.
How it runs
It won't stay running unless I have some throttle on, despite changing the idle setting.
There's a lot of popping.
It bogs down when I try to rev it up.
It backfires sometimes when I'm trying to start it
I sometimes experience blow back (an air pop) from the carb/air box
It doesn't exactly start easy. My foot hurts from kicking it 50 times.
The choke doesn't stay on. Is this normal? I push it down and it creeps back up.
I don't believe there's been any major work done to this engine. I could be wrong. The bike has around 6000 miles on it.
Any guidance is appreciated.
