Re: Lets get back to oilheads...throttle body question

Thanks, Pascal, et al

I thought (hoped) replacing o-rings would solve my problem...not so.  
The throttle bodies seem to synch ok under load, but idle is 
erratic...bypass screws still widely apart to balance.  I'll check shaft 
play tomorrow, spray some carb cleaner at them, and clean out the bypass 
screws (maybe there's a bad o-ring in there).  Throttle stops seem 
tight, so I don't think there's any sense in trying to zero them if the 
butterfly shaft bushings are worn out.  Many thanks.
