Well decided to order a new spark plug and the air filter. Installed them yesterday but could not get the bike to start. Went out today, drained the gas from the carb and tried again. No go so pulled the plug and verified spark, squirted starting fluid down the spark plug hole and still nothing. Full throttle no choke, full throttle choke. full throttle and partial choke. The last one eventually got a bark. Switched to partial throttle and kept on kicking until things warmed up enough to stay running. Turned the choke off and adjusted both the air and throttle screws.
My guess is that the carb was set too rich. Initial runs were without an air filter so adding a filter made it more rich again. When it stops raining tomorrow or Tuesday, will see if it will start with choke on and allow the choke to be open after a minute.
