Okay, So I am a little stumped and hoping to tap into the knowledge base here.
So I just recently rebuilt a '73 850 and for some reason it isn't starting. I understand this can be a multitude of things, however let me do a little explaining. So when I first did the initial rebuild, the bike would start after a few kicks (warm summer months). Although the bike would start, it was only running on one cylinder. The other cylinder problem was not a timing or spark issue and the exhaust would have a slight suction if you placed your hand on the muffler, and after some investigating I couldn't figure it out but had to leave home. After re-torquing the head due to an oil leak, I ensured the valve lash was still spot on. After doing this and now working on the bike after a couple months at sea in the winter time the thing wont start. The bike is getting a solid spark on both cylinders and the timing is 31deg on one cylinder and 28deg on the other. The timing was set when the bike was running - not dead on, but well within the ballpark for the bike to start. When kicking the bike over there is a fuel residue on both sparkplug - slightly more on the right spark plug but noticeable on both however the goshdarn thing just wont start. Any ideas?
Thank you in advance and have a Happy Thanksgiving,

Also anyone in the Charlotte, NC area?
