Carbs issue or ...?

This post was updated on .
I started the bike up today and found out  there's just number 1 cylinder is working the other 3 were cold. I checked the coil wires first , 3 of them showed 4.8 ohm except #1 is 5.2 ohm . I switched the wires and they seemed to be working fine . I pulled the carbs off the bike and found 2 of the rubber plugs are swimming in the bowls ( I also cleaned the carbs ) They don't stay in their places tight . I thought it might be the problem that too much gas is going in engine or something ells is not working right !?
and also one of the mixture screw O rings is damaged so already ordered the part .

The rubber plugs you found swimming, do you mean the ones that cap that pilot jet off?

If those are loose you might just need to give the carbs a good once over. If those are what I think they are you're bike can't get fuel to idle with those off.

Yep. That's what I thought you meant. Do you have all four of them? Do they fit nice and snug?

You might be able to get by with a basic clean,adjust and reassemble.

2 of them fit nicely but other 2 don't , so already ordered a set of 4 , i cleaned the carbs and bench synched them 2 days ago and as soon as i reassemble and put them back on the bike will synch them more properly with carb synchronizer , hope they are gonna work with no hassle .it's about right time here in Brooklyn to get her running and enjoy the weather
