Topic: carb problem cb750f

[Outboardbill]

I have the carbs apart from my 1978 cb750f.  They have been soaking in Yamaha carb dip 50% solution for four hours.  Everything looked clean until The 80psi compressed air would not go through the pressed in slow speed jet in three of the carbs.  The first one opened up nicely.  I know that a wire is not supposed to be used.  The book says the jets are pressed in and cannot be removed.  Has anyone ever tried to remove one of these jets?  Any other ideas for cleaning?  Maybe just leave it in the solution for more hours?

Myriad threads about this.  The slow jets can and must be yanked out, cleaned and pressed back in after the passageways behind them are proven to be clear to all four exits.

I've used the bristles from a broom or thin fishing line (anything nylon or plastic ie, not abrasive like metal) to clear the passages on my '76 jets.  Just a thought.  Not exactly sure what the '78 jets look like.

use some vise grips but not to tight. Lock them on and gentley wiggle clockwise and counterclockwise. It will lossen up then pull out. I did it to my new set of f carbs not less then an hour ago.
