Right cyclinder firing? Video

[Lance Weersma]

Hey there gents would love your imput. Trying to get the carbs tuned in and question how well right cyclinder is firing.
I am getting spark. I pulled both plugs and grounded them to the frame.
Carbs have been rebuilt and cleans again last night.
Video should explain the rest.

Yep, the right carb needs some work.
There's the usual "sparkle clean" routines, but you may also be dealing with the more difficult "age, wear, abuse, damage, warpage" possibilities.

Have a look at the Tech section's carb>shafts seals thread, and my broken album "carb rebuild" for ideas on the unusual.

Oops, and this one:
