Bad day.

Took the teener ('74 2.0) for a test drive last night. first trip since the rebuild. Made it almost 3 miles. struggled to keep it from stalling, managed to get it up to 60, then total loss of power. Couldn't even get up a hill - towed home. She had all the signs of a blown MPS: extremely rich, hard to start.

This is getting old.

Options: Try to find a reasonable, decent MPS.
Switch to carbs - which I am seriously considering because I've had to fix broken wires on the harness 4 times already. When it has run (400 miles in a year) I had to constantly feather the pedal to keep it from losing power (another problem?). Just wondering how much this old FI system has left. I don't want to go too high end, because I'm upside down in this car already.

I am not trying to restart the carb vs. EFI debate. So, I'll stick with one specific question:

Are dual Weber 34 ICT's sufficient for a 2056?

This is a daily driver (hopefully), but I also don't want to get passed by some old lady in a miata.

Thanks for the advice.

For daily driving, you'll always be happier carbs that are with too small than you will with carbs that are too large. You'll get a few more HP out of 40's and with a 2056 they should run great, not too big, and it will run great with 34's also but you'll always know that you left a few HP on the table.
