SO ,like a ham fisted ape i messes up the secondary air door spring in the refurb street demon I put on my truck.

Send me a PM with your address. I'll send you a Thermoquad spring. They fit and work fine.

Looks like Rusty took care of you! Nice.

But, for future reference...Allstate Carburetor over in NY usually has lots of the discontinued and hard-to-find goodies for Demons and Holleys.

I have a very unique situation with my Holly Street demons... Running two of them at once is near unheard of. There's one old hot rod article when they first came out about 12 or 13 years ago where they put two on a Ford engine. The guy did some special deal where he drilled 9/16 holes in the secondaries...
Anyways I called the Holly tech line asking about a couple of those because I didn't want to drill holes in mine and be stuck. They gladly sent me a couple sets for free... So I could give it a try and I did and it worked and now I have four extra rear flap doors. .

Be very careful with that 7/16 snot and that flat head screw to adjust that air door because it's going into that cheap cast upper housing and if it strips you're screwed...

9/16"? Are you sure about that? That's a HUGE percentage of the secondary bore volume.

Of course my engine is a 410 and this is the only article I could find on the entire internet about putting on twin Street demons.. the phone number is at the bottom of the article and I called them and when I did finally get a hold of somebody they were very unhelpful...
Arrogant and passive to say the best...

Got it yesterday. Installed about ten minutes ago. Actually reading the directions on tuning this thing again now.

Thank you again. You are a lifesaver.

Glad I could help!

Reminded me of when I messed up one on a TQ years ago.
My tip is hold the door all the way open when tightening, you'll feel when you're approaching coil bind.
Stop or you'll ruin another one!
Glad you found a replacement.

Reading the instructions? What a novel idea LOL.. could be shocked to know how many people buy a carburetor and absolutely never read the instructions on how to tune it or operate it.. it's public knowledge it's not a secret lol...

Well, I always say reading instructions is cheating but I've never been that bright.

Oops

I get it it's dry reading and nobody wants to do it, I mean nobody, but if you read it and yes read it twice because you're going to skip over the stuff that sounds boring it's amazing how much more you can do with it..

I'm just glad every instruction doesn't start with "disconnect the negative battery cable" like an old Chilton manual.
