Could it be you have a non LoM carb with a LoM dizzy?
I read somewhere that this can cause poor fuel mileage and sluggish performance. I'm not sure how to read the carb #'s to determine which type it is. I also don't have a clue if there were any 223 dizzys made without LoM

The second glass bowl carb I bought is for a car without a LoM. I now have to change dizzy to make the stuff I have work on the 2x1 offy. Recommendations or link to what dizzy to buy and were to get it? Can my dizzy be modified?

Read this all the way through: Help with 215 OHV I6 2x1 set up - The Ford Barn. There are instructions at the end on how to convert a later style 300 dizzy to use with the 215/223 engine.

If you're persistent, you can make it work. I just got tired of it not working right and wanted to drive the truck without dropping more money into it. Let us know how you make out.

It has the 5/16 opening for the later oil pump drive shaft used on the Duraspark dizzys. IIRC I bought a new drive shaft and cut it to fit. I had to have the stock dist gear opened up to fit the larger shaft of the Duraspark dist. I had a machinist do it as I know one and we exchange favors on a routine basis.
Seems like a lot of work and it is. But is it worth it? I think so. Ford Duraspark is, IMO, the best dizzy ever made.

Because I was fed up with it. My problem was that I couldn't get the carbs synced well enough. It would work perfect one day, then another would be crappy.

When you were fooling around with your duel set up what jets were you using? I got a 64 and a 66 but I think its too much. Any recommendations?
