As a mechanic you have to test components and diagnose what the engine is trying to tell you.
Carbs that were rebuilt from some guy 10 years ago, but he was good or the bike ran fine up until 6 months ago when I got out of bed turned the key and it was running crummy. More like it never ran good and it was 5 years ago. I just gotta :ROFL:.
Unknown to you engine may not be capable of ever running right without doing a compression test first for general health of the inners. Then you move on to the ign system for spark health. Does it backfire or pop through the carbs, then we go to ign timing issues assuming cylinders are getting fuel. Then check fuel delivery system. Are vacuum hoses missing or cracked. Then move to carbs to get it running.
Then diagnose which cylinders are the troubled ones and whether it is rich or lean. Pull the plugs, is one or more gas soaked and others dry. Start it up when cold and shut right down, feel the headers, is one or more cold. Etc, Etc,Etc.
Pulling plug wires and a can of carb clean spray will help you quickly isolate the problems.
