#2 throttle plate not seated

[dfwthompson]

Guys....cannot tell you how much this site has helped me not to mention the money I have saved. MANY THANKS to all of you!!

 

I'm having an issue with #2 on my '83 V std not closing completely and not having any luck finding someone who has experienced the same problem. Thought I read somewhere in the svc manual about a barrel adj but can't find it or maybe dreamed it one. After trying every adjustment at grip and carb I noticed when I crank back on the throttle a barrel on the cable compresses a spring on the throttle stop at the top of #1 and the throttle plate seats as it should. Is there an adjustment I'm not seeing... either on the spring or the barrel? Thanks again!!

I suspect that your carb synchronization is off.

If #2 is the ONLY throttle plate not fully closed and the rest ARE fully closed, back off the other synch screws until loose and redo the carb synchronization. Number 2 carb plate is adjusted with the idle screw knob and then the other cylinders are matched to number 2.

Thanks Kevin....all sync screws backed out to loose. #1 and #3 fully close, #4 throttle plate looks like #2 when throttle is backed off with a little pressure. Plates moves just a hair to fully seat. Will sync #1 and #2 by ear first before attaching the carbtune. Will let you know how the new diaphragms work or I'll be asking for more help?? I ordered them a few yrs ago. I guess it's about time. Thanks again for your response.

#2 throttle plate is adjusted by the idle setting screw.

 

No 'sync' screw for this carb. Set #2 closed then match other 3 to it.

 

I see Prarriehammer already mentioned this after I rerad post, hate when I double up on someones already correct answer.
