I've searched the forums and have not found the info I'm looking for. My GL1100 isn't firing on the #1&3 cylinders at low RPM. The weather has been preventing me from riding it to find out if this is a problem all time or not. I get a slight amount of suction at the tail pipe on the right side and it never gets hot. I'm getting spark and just replaced the plugs. The bike is new to me but the previous owner says he recently rebuilt the ignition system. I've lost his number so I can't ask him for a list of what he's done. It's hard to start sometimes and the idle is set really low. When it's warm it idles at about 700-800 rpm but will usually die if you let it idle for a few minutes. I know the carbs need to be synced and I'm pretty sure the needle and seats are worn. (left the petcock open over night once and had quiet a bit of fuel in the #4 cylinder) What I want to do is check the timing, set the idle, and balance the carbs. What I don't know is what order should I do this in and what parts should I be replacing or cleaning to make sure I'm doing it right. Any input will be greatly appreciated.
