Biggest problem is what to do with those leftover parts?? LOL

Thanks so much. Is it better to not get the Daytinna kit then?

John

No.

The Daytona kit is OK. The narrative was to advise you of the two designs, and what to look out for in the flat disk design, versus the cone shape.

The installed height of the 'flat disk' is less than the 'needle and seat' historic design, therefore if the unit is not shimmed the float tang must be bent to make up of the reduced height. That amount of tang bending places the valve/float tang contact point off center and that puts a side load of the valve. At some point the valve is 'rocked' of the seat and flooding is likely.

The instructions are quite clear on the shimming procedure. Once the contact point is centered the 'flat disk' design has some advantages . . . at least that's what the pamphlet says.

thanks!

FYI: don't sand blast the carb!

Another guy on another site was complaining when his rebuild 4 bbl didn't work so good after he sand blasted it first and rebuilt.
Use the soaking type carb cleaner. If any part needs de-scaled later, then carefully bead the part, not the body. Too many orifices to clog. Poke out the any holes with a fine wire.

Great point.

The carb is mostly apart. The screws that hold on the butterflies are braded on the end. To take them off will I need to grind the ends off? Also I tried to unscrew one before realizing it was braded and I sheared the head off any suggestion of how to get the screw out?

Thanks.

Don't take the butterflies off unless you absolutely must!

The secondary butterfly shaft is basically stuck in the bore wont turn. It needs to come out doesn't it?

Typically if you soak it in carburetor cleaner it will free up. Unless physically broken or bent, there is never a reason to remove them.
