[firebird*boz]

Hello all, does anyone know if the .044 primary rods for sale at cliffs, suit all aplications
( i.e. - like the DA secondary rods).

any help would be great. Thanks, Boz

The rods shown on the website are for the later style carburetors.  We use them for all carbs set-up here, matching up the jets and airbleeds accordingly.

We also sell the longer early style metering rods in .039", .042" and .043"....Cliff

I still don't understand why there is not a bigger assortment of primary rods for the later carbs. If there was, it seems like it would be a whole lot easier to fine tune by putting a different metering rod in as opposed to disassemble and block off and drill and clean and re-assemble and re-install. I've been asking for awhile, never have gotten a straight answer.

   ScottyP, dont take this as gospel but, I think the 44 rods are what you would call "very tunable" and they cover a wider range due to their design. Something about the taper and where it starts and ends and the amount of taper compared to the length. the other rods dont taper as much so the tunability witth the APT is limited (wit the others). That reminds me I need to get a set of them. LOL
  How many jet sizes would they cover? (In percentages that is) I dont know. but they somewhat eliminate the need for a large assortment of different rods for the later carbs. 

Cliff, do you mean to say that you can use them in the earlier carbs also?  (when you say all carbs)
