I have a bad, or no, micro switch on the Spica on my '74 2000GTV. Is the switch internal or external to the pump? My mechanic seems to want to avoid the issue, saying that we will probably find other things wrong with the system and have to ship it out to have the pum redone by Wes. Is this correct, or can I just live with the grumbling and backfires?

Thanks

The pump must be off the engine to replace the microswitch. Once on the bench, it's a 5 minute job to install and adjust.

If the system is properly setup, throttle plates correctly adjusted and the mixture correct, you should have very minimal or no backfiring, except for when the TA is still enriching the mixture on a cold engine. My advice, if you're having backfiring is to examine the tune of the system.

The microswitch on my Alfa is inop, but I don't get any backfiring. Next time I have the pump off the engine, I'll replace it, but it's not worth pulling the pump just for that.
