Smoking on one side

Stock carbs?

[ClayAiken]

I think everything was sealed well. The guy that helped me took a lot of time showing me everything and making sure I did it right. I just called him after I read all that and he is still convinced I have a carb problem. Is that possible?

Are they synced?

[Lodge]

They are stock carbs. 250 mains. Left all other jets alone. Cleaned the one under the float and the air screws are synced at 1.5 turns. When I put them back on I had dirt in them but I just tore them down and cleaned all I could. Choke seems more sticky than before. Could that do anything? Crossover tube is new

[Larry's Shee]

Clean both carbs pussy clean. That means taking them comepletely apart. Set float height, Sync carbs, new plugs, leak down test. Has coolant gone down ?

 

No offense to you or the race car builder, but RTV is not the proper/prefered sealent. Yamabond or 3bond for case halves.

If you have a cool head sounds like an o ring fell out of place and got tore during assembly they won't burn much coolant but will smoke like a freight train and anti freeze will tear a bearing out faster than you can blink your eyes. Pull your head back off and look for smashed or torn o ring and make sure to use a small amount of Vaseline or silicone to hold them o rings in place when setting head back on jugs.
