(What causes) temporary high idle at stoplight after full throttle run... I can blip throttle and it goes back to normal idle..... is there an explaination...?
sticky throttle grip, sticky throttle cable, sticky slide, or cable end doesnt pop back into its cup.
Not... It is definitely not that... it's in the air/idle jet circuit and I have a 45 idle jet and putting my hand over stack quickly gets it to idle normal again...Thanks for the response...I am hoping someone has had the same issue can explain...
Use spring loaded float needle maybe,
Could be float level/gas level in bowl, gas puddling, vibration etc.
Idle jet sets higher then main jet in carb bowl,
I did not realize they had spring loaded needle until now. Mine has stiff needle and I already bought a bowl that doesn't hit the mag cover but was trying to get it tuned in before installing it...Puddling sounds like a good reason for the problem too...Thanks...
Could be air fuel mixture screw setting.
You think your idle might be too lean?
Are you getting any crazy spikes in temp?
Lean is what I was thinking too but I think I solved it as the quick change nut on the bowl was still touching the mag cover so I swapped it out with a plain bowl and I guess the vibration was the problem....It's weird what harmonics can do....
My guess is your getting into the next circuit of the carb.
My guess would be air in the idle circuit causing a brief high idle at a stop light.
