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.

PLEASE,- PLEASE don,t go with the single barrel 34 ict webers. I have had on

my 73, 1.7 , Single Carb, often refered as a Boat Archor, 34 ict Webers, and

40IDF Webers. First 2 ran like SHIT. Had all kinds of problems with driveabilty.

34 ITC's remember I had a 1.7 yours is a 2056.

What is wrong with them ?????

Well lets start a low speed, ( these were fresh rebuild) Up to 35 mph it ran so

bad , in order to cross a intersection you better have 2 blocks clearence, or really

over rev. the engine and slip the clutch, ( that is good for a long life).

High speed:

Above 60 MPH it wouldn't get out of it's own way. Above that NO

excelleration, if you were on a limited access highway you stay in your own lane.

Just don't try to pass that one car we all run into that drives 55 in a 70 mph zone

it will take you 2 to 3 miles to do it.
I think they are dangerous, on a 1.7 Let alone a 2056!!!!!!! My 2 Cents

Now for the good, mileage the highest highway i got was 39 mpg

Please you would be in danger with the 34's.!!!!!!!!

40idf's run great , mileage in the low 30's IMO difference

is not worth the risk. If you race then 44 IDF'S may be the right choice.
