well here we go....
Set out to tune y twin Su's, has been very smoky of late...
anyway, balanced with the air/flow meter....
screwed the fuel adjust all the way up and then down a 1/2 turn...
began adjusting until seemed right...however....
when i rev to 3.5k+ starts to sputter and fire off a bit of black smoke....(rich?)
BUT when i lift EITHER of the pistons in the carby throats the engine dies (lean?)
furthermore, after a bit of playing would rev slightly higher but then backfire fuel out of carby (flames once!)....that was when i stopped.
Any advice would be great...have been through the haynes manual, my SU manual and any others i had but to no avail.
