Last fall I replaced the rubber carb mounts on the TR7. At the same time I put a seal and gasket kit in both carbs and replaced the throttle butterflies. I replaced the butterflies because the edges appeared to be worn and scored. I put it all back together and all was well, (even got the idle speed down to about 900 rpm warm. The problem I'm having is that I seem to have a "catch" in the throttle at about 1/3 peddle, it seem to be just a sticky spot, however the resistance needed to overcome it increases with the engine temp. I thought maybe the shafts were worn, however they appear to be fine. Also the rear carb mount has failed, rubber seperated cleanly from the metal, I contacted VB and with a little whining (from me) they agreed to replace them. I thought the two were maybe related, but I dont think they are. Anybody have any suggestions, ideas, or input?
