Carbs, 9300'above sea level Options

[6freak]

getten ready to change the carbs go`n down 10 ..so if there 150 mains i go down to 140 mains and so on.. sound ok ?....

Going down on the mains is the right idea. You could go with bigger A/C jets but they have more of an effect at higher velocities. The smaller mains will help you from 3K and up. You might be rich up to 3K since your keeping the same idle jets. Since it's an AX I don't expect you to be that low except at the start. You can tweek your idle mixture screws in a bit to help but the fuel from the progression ports don't run through the mixture screw. You could go crazy and step down your idle jets but like I said your engine will most likely be running on the mains 99% of the time.

Thanks ...I was told go down 10 (mains)and then even maybe up to 60 on the idles? ...the more i get into it the more i get lost .....I`m so screwed ..LMAO...But yes it will be hi revs pretty much from start to stop...Thanks for help`n figure this out

Ha! (IMG:style_emoticons/default/biggrin.gif) .... cant you simply adjust your tire pressures to what you want them to be when you get here?

We also have electricity and running water - no need to plan on bringing your own!!! (IMG:style_emoticons/default/biggrin.gif)

Air pressure
Sea level - 14.7 psi
10,000 feet - 10.2 psi

Here maybe you guys that are worried about tire pressure can figure it out based on the info here:

Yes tire pressures are easy fix`s ...no issues there ..so here`s what Im gonna do go down 10 on the main jets check and make sure i have at least 60 idles and call it good and hope she go`s
And yes i have a generator I was thinking of bringing and a compressor and 5gallons of water also to wash my hands after wheel changes (IMG:style_emoticons/default/lol-2.gif) .

Hi Mike -
Look forward to meeting you. I should be up there no later than 10am on Monday - and that *should* include hitting the grocery store on the way. I will get the grills up and running as soon as folks start to arrive and we will go all day. We will start round 2 for dinner - probably do something a bit nicer like steak/chicken fajitas.

Bottom line, once I get up there, the doors are open - you cant be too early or late. This whole thing was to add to the fun, not cause any additional stress or planning.

I will throw another post up next week with the address/map and my cell phone.

I am really looking forward to all of this!

What size idle jets are you running now?

60's seem huge to me. Heck a 2.0/4 runs a smaller jet than that.

Info I have for stock 914/6 40IDTP

Vents = 27
main jet = 1.05
AC = 1.70
ET = F1
Idle = 50

If your running IDA's

Vents = 42
Main Jet = 1.70
AC = 1.45
ET = F24
Idle = 50

Not to start this crap up again ...but here what i did last nite pulled the 125 mains and went 105(115 on order) hope they show up before the event...Pulled the 50 idles and went 45`s ...Car ran like crap i mean really bad ..sooo im think`n! go back to 50 idles, smooth out pretty good enough to go for a drive ...car has a good out of the hole snap but then stumbles at around 3500rpm and then again at 5500rpm ..Thats why im think`n 115 mains will stop that stumble and maybe go 55 idles...Iv got a copy of my book with the settings if i can fiure out how to post it ...yes it the IDA`s
