Who jetted the carb? You or someone else. Did you or they Write down All the numbers? OEM jets or some brand of jet kit?
'Choke' lever pushed Forward for normal run position. Pull Rearward for Cold Start-up.
Take the fuel tank off.
Is the plastic choke 'nut' broken? If not, is the cable properly clipped into the plastic nut? The cable slack adjuster is just 4-6 inches above and ahead of the carb, screw it all the way together. Best to add a small remote fuel supply tank and be sure to plug the vacuum nipple. Now start the engine, allow to idle and warm-up a minute or two.
Now gently Pull the choke lever towards yourself, you should hear the exhaust note change and the idle speed fade as the cold start enrichner jet opens.
I like to then adjust the cable slack so that the 1st 1/8th lever movement is just taking up the cable slack. At full lever pull-back the choke lever may not quite top-out in the control pod.
ps, If it is still running, your spark plug is still OK, imo only.
Modify at "YOUR OWN RISK"!
