CB77 right cylinder not firing properly

[Jim Stuart]

I don't know if I am doing this correctly, but I just unstored my 1967 CB77 305. Upon starting, following timing and plug instructions, I find the right cylinder is not firing properly. Compression seems good, plug does foul. Air adjustment screw does nothing. Left cylinder fires well, and air screw does have effect. Do I have a carb float problem on the right?

Thanks, Jim

You have a plugged slow speed jet. .........................lm

O.K. Guys, I need help. The right carb, which has been cleaned many, many times is still not cooperating. I fire it up, and the left is running fine. Did all the tuning stuff. The air jet has almost no effect. If I turn it all the way in, and begin backing it out, I will get a couple fires out of the cylinder. Other than that it has no effect. The idle jet is clear, I did a compression check this morning and both are in the 120# range. I am sure I am overlooking something simple. Any comments??

Gas in the bowl?
Plugged slow speed passage?. ...............lm

There is gas in the bowl. Have shot thru Carb cleaner and its clear. Everything is clean, just as in the left carb.

Well if the caeb is OK then it heads to the top of the engine.
Valves! Points set correctly. Spark at the plug.
Good Luck. ............lm

I will check valve clearance tomorrow. If they were not correct, would I not get good compression??? Spark jumps a 1/4" gap with a spark tester. I have a set of 8 plugs now, due to replacing them every time I do something different.
