Sorry to hijack an allready hijacked thread, but its not often that you see detailed descriptions like lynn's.



so a question for you lynn, i have a holley 600 that ran great for awhile there, until i went to install a heat shield, i broke the ear off the base plate and could only fidn a baseplate for a holley 650.



it was all machined properly to match up with the one sent by racing beat, i even bored out the bottom of the carb to match up with the eight of an inch difference with the baseplate.



however i did not match the manifold port size.



i hooked it up again and it ran really shaky for about 2 days, would hold a rough rought shaky idle at 1.2k



i went out for a nice drive in the cold winter air for a night, parked it, went out hte next morning to get to work, cranked it over, it shaked and stuttered through every rpm while cranking qnd would not hold an idle unless i held my foot on the accelerator, and after a few moments of that, it would drop idle and stall with my foot still holding the accelrator down.
