cis-e dist. rebuildable???

[THayes302 at aol.com]

Hi Guys,
I would like to hear any suggestions or experiences concerning rebuilt fuel distributors.  My Bentley suggests that these things should not be tampered with other than replacing the stop screw o-ring.  I know that I have a fuel distribution problem on my 4kq because spray pattern is bad and injector volume is unequal.  I have been trying to call the Parts Connection to get more info on their fuel dist. kit to see if rebuuilding my own dist. is possible.  Any input would be greatly appreciated.  On a side note I did check fuel psi, control psi, and volume and everything is within specs.  I would like to thank the fellow lister who turned me on to BMP for the fuel tester kit, and Huw for info on jumpering fuel pump.
Thanks,
Todd
