Buck tell me if pics come thru. I am having the hardest damn time texting you. I have to send a message and then it rejects it and then have to resend it as a text message. Stupid I phones
I tell you what. You said it will start if you put fuel in the cylinder. Get it started, choke it(full choke)and see if the fuel flows between the carbs. Try this first
I would say that there is a clogged up passage on the choke circuit. Loosen the screws on the carb bowls and make sure (again) that fuel will flow out of the bowls. If it does then that left carb is still dirty
It won't be a lot but when you kick it with the choke on it will kinda mist thru. Look real close. Kick it ten ten times with the choke on then remove tube and see if there is evidence of fuel
