carb second level of H*ll

Rick - I'm reaching for the dictionary again!

 

What will a color tune plug do? Not sure to there use I always used an air fuel meter to tune with ( autos) have a set up for tuning bikes with this now so I can get real time air fuel on it. The screws you are referring to are air screws by choke? They are adjusting only at idle? The low to mid air fuel is set by the needle correct? Top end and high mid is off the jet size witch is stock here only mod to bike is a uni filter

 

Well another dead end going to look for new Carb and coil maby that will work

 

120 psi cold dry check all across one number 3 is at 119 lol good spark across also idlse good valves all at spec got to be the #1 Carb is messed up any clues idles good but fouls under load steady throttle

 

Took Carb #1 apart top half cleaner run threw all air jet ports blew it out put back together same thing run it for five minutes fouls out #1 plug. The needle seems to stick when pushed up on the Carb tearing another apart to see if changing from one Carb to another will change this or are these not interchange with one to another?

 

One and two cylinder are at different hightails on the needle in the plunger swapping them now hope this works

 

Found my problem or so I think one of the needles are longer than the rest can not find a mention of adjustment on these. Is the long one wrong for the carb or are they adjustibule ? What is the hight to set at? and how ?

Sombody please tell me that the needle at the end of this thing is adjustabule...

 

not really but they are removable there is a plastic hex head inside the piston that needs to be turned a little to release it. there is a spring so be careful things don't go flying. there should be a number cast into the plastic end of the needle to let you know what you have and need.
