Hi all,

I recently picked up a demon jr 525 carb for my 56 sunliner.  I had read up on here about swapping out the viton needle for a steel one due to alchol in the gas softening the viton tip and the needle sticking.  Well, I checked an older holley and sure enough, the needle tip was soft, so ive decided to swap to steel.

After reading on here, someone else (I apologize i dont recall who right now) had said they swapped to a .130 steel needle, so i ordered a pair.  Went to put them in today, and hte needles i took out looked to have "111" stamped on them.  Curious, I checked out barry grants website, and their spec sheet lists the demon jrs as taking a .097 needle.  So question is: should i stick with the .097?  What is the downside of sticking with the .130 I just put in (seeing as how the .097 in steel is nearly $40!!!).

Any and all comments are appreciated!

BTW, Barry grants website has a sweet looking Y block on their home page promoting their 98 series carbs....

THANKS!!!
