Thanks to all who have responded. We've ordered some parts and made some calls. Joe Curto told me that he's had a few TR's come in with after-market MECHANICAL pumps that are putting out too high a pressure. Anyone else run into that? We'll put the old pump back on or get a good regulator and gauge. The carbs are FZX 1258's which calls for a standard metering needle of "ABT". Also, I hate to admit I didn't notice that there were no piston springs (I'm used to working on H1's for the Bugeye which have no springs but I should have caught that anyway...duh.)
Given the fact that the car is desmogged is the timing still 10* BTDC? Neil, I'm not sure what you mean by "reversion" issues? I shall find the answers to your questions. Again thanks for the help...we'll see what Thursday brings! Dave Neil Penberthy wrote: > I'd suggest checking that you have the right needle.
