So I left the air filter off and the plugs out and let everything air out for a couple days, petcock off of course. Fired it up, smoke everywhere, ran on two, 10 seconds and shut it down, and there is fuel everywhere on the ground, under left side crank case and left exhaust, 🤷‍♂️ fuel dumping...

So it will dump into the cylinder eventually then yes?

I have the plugs out and the airbox open and I was gonna try one last time to get it fire on all four.

If it was my bike would probably be done by now, i’ve done bike carbs a million times but it’s somebody else’s. Even if he was willing to pay me a fair rate to do it I really don’t think I want to. 🙄 BTW I assume these carbs have an overflow drain because I wonder why gas is in that cylinder. it...

Well, it won’t idle. it’ll run ok if you rev, it sounds terrible at idle, lots of knocking which I understand is normal when only a couple cylinders are firing. And it won’t stay idling without throttle input. I think it’s highly unlikely this thing is gonna resurrect itself without a complete...

He did ride it to my house. 1.5 miles with zero brakes and running on 2 maybe 3 cylinders

Okay, good insight. It’s not my bike. It’s a friend of a friend and I don’t want to go that deep. Something I don’t want to do means it would cost the owner far more than the bike is worth. One of my own bike’s need this level of work and I haven’t done it in yet! Honestly what is an 81...

So I pulled the plugs on the left bank to check for Spark turned it over and vomited gas out of the left rear cylinder so I’m thinking stuck float needle seat dumping gas through the carb into the cylinder so a carb rebuild is in order no?

sounds like a good plan, BTW it's the left two not seeming to fire (no heat on exhaust) so knowing the coils are paired front and rear makes it less likely to be electrical I suppose. I will try this

Hey all, I have a friend of a friend's '81 1100 interstate. He brought it to me for some brake work and a little tune-up but it was only running on 3, hadn't been on the road in a few years, I got all the old gas out, added some SeaFoam, drained the carb on the dead cylinder, ran it a bit...
