CA95 Starting issues

Coast to Coast
Am helping a buddy with his CA95 1964. It was running great but a PO did a nefarious KREEM job and the carbs got filled with crap and the bike was running poorly as a result. I took off the tank, cleaned an re-sealed, cleaned the carb and reassembled. Fuel supply is fine, and bike is producing spark. The bike has an open type air filter. It is not starting. I have tried every variation of the air/fuel mixture but still no dice. I can hear it's not even close.
One thing I did notice is that he had somehow reassembled the "power air jet" with a number 100 jet, when it is listed as 130. The only replacement in the keyster kit was a 140 so I put that in to no avail. It was running previously with the 100 though but I have exhausted the variations to make that run correctly.
I am sure, as usual, there is a simple carb problem to address but I am having trouble finding it. Can you guys make some suggestions about where to look? Everything corresponds to the correct position. It's baffling me
Thanks, Mike
 
clogged exhaust?

oh and btw whats your compression @?

if its low check for tight valves, these things tend to beat the valve seat into the head after many miles which makes the valve tight.
 
Dumb question but have you checked valve clearances, done a timing job etc?
 
The only reason I haven't checked clearances etc is because he bought it from a dude that regularly restores dreams. I rode it a week or two before the carb problem and it was tuned really nicely and running well. I'm thinking perhaps I'll go over the carb again on the weekend again and start from scratch. Failing that, I'll recheck the valve clearances etc
 
I've never used Keyster, but I've heard a few swear words thrown in their direction more than once. You should be able to pick up new brass from JetsRUs or a similar website. Double-check everything in the carbs and make sure jets didn't get placed in the wrong holes.

Also.. try injecting a bit of gas into each cylinder (use a syringe and go through the plug holes) and see if that helps. When my CX500 sits over the winter, it's a real pain to get running again and it needs more fuel than the choke will provide.
