LOL... Sputtering and pumping happens in the heat of summer as well as in winter! Here is what I do: Turn on the ignition and let the system build some pressure while I put on my seat belt. Next I slowly pump the accelerator 5 times. Finally I hit the starter. It usually takes no more than 2 tries. As soon as it catches I pull up the hand throttle and let the carb’s “clear out”. As soon as they are running smooth, I lower the idle to 2K and off I go. All this takes no more than 2 minutes on a cold morning. Within 3 miles I release the hand throttle and things are pretty smooth until it is fully warmed up.
If you go with Webers, make sure they are freshly rebuilt by someone like Eurometrix or Bieker. You must start with a great set or it will be a pain to maintain them. Lots of people on the board can help setting them up, but I would recommend taking the car to a shop that knows carb’s and have them dyno tuned. This way you will know they are really right.
On the other hand, for a few more $$$ you can go with new PMO’s. I replaced my worn out –total POS- Webers with PMO’s and haven’t looked back. They are smoother, better mileage -22+ on the highway at 75- and a lot more power. First pull on the dyno they were up 20 over the Webers and finished up 27 over them. And Richard Parr is first rate to work with on them.
Hope this is what you were looking for.
