EA81 hessitation blues

[Rust]

Since my loyale is down I've been using my 85 hitachi carbed brat and it keeps hessitating/hiccuping going up hill or at high rpms.

 

I've replaced all the rubber fuel lines, new fuel filter, new vapor seperator, new generic electric fuel pump......but it still hessitates/hiccups going uphill:confused:

 

Before I start pulling the carb apart to clean the jets is there anything else that could be blocking fuel getting to the engine?

Still got a cat on it? Im wondering if its plugged up. The cat on the coupe was completely clogged and was most likely part of the running problems it had.

 

How are the tune-up items on the motor? plugs, wires rotor, cap.
