    So I re-rebuilt the carb today. Didn't replace all parts but most.



    The bike runs fine threw the gears, starts right up but the idle I just caint seem to tune.



    I did adjust the pilot screw accordimgl but it seems as if at idle the bike stumbles and chokes and hesitates.



    Is this symptom called an "off idle stumble".



    I will say how ever the pilot screw oring is a little worn and I will be replacing that. Try that tomorrow.



    I'm kinda stumped.



    Anyone ever have the same issues.



    And I cannot say that before the rebuild that it stumbled at idle cause it wasn't running when I got it.

    Soo,



    Replaced the oring and readjusted pilot screw. It's better, no coughing or hesitation at idle but its just not 100 % dialed in yet,



    Butt I did manage to sneak in ye another mod.

    Yeah. I stole the idea from some one on here



    I basically cut the head off a longer bolt then drilled a hole for the pin. Easy peasy

    So I really dialed in my carb today with some new parts. One of which was an up size in jet. I did a #118 from a 114 and also opened up the screw so the throttle cable would open up all the way. I for sure now will be doing the shim mod



    Just thought I'd share and highly recommend to rejet. I'm sure conditions and atmosphere play a roll. Soo to all the southeast coasters a #118 and your good.
