Down under, an idiot and a 400F

[crazypj]

If you have bodies completely stripped, it's a good idea to soak them in warm water to make sure all the soda gets dissolved out.
I've had a few sets sent formodification, dust gets in everywhere them normal water vapor in the air starts corrosion
I heard that on steel soda forms a protective layer, I guess zinc die cast carb bodies are completely different?

PJ I will soak them too, just water or should I dump them is a bath of mineral turps (or some other nasty chemical)?

Also with rebuilding them what should I keep and what should get replaced (considering I'm going to 466 kit and probably pods over stacks). Currently these bits are out of the carbs:

1. Needle
2. Pilot jet
3. Main jet
4. Float and float valve

I've not taken the needle jet out yet as it looks pressed in and I didn't want to damage it.

Also do you have some guidance on the jets I should buy?

 

[crazypj]

Just use warm water
I fill sink up and let them sit, blow out and use hot airgun to dry them off
I have a piece of 1/4" dia 6061 turned down to fit needle jet on 350/360 carbs, sometimes they slide out easy other times they need some 'persuasion'

PJ, That's way too sophisticated. So many Hondas use versions of the same needle jet and they all come out easily with a suitable drift.

For those of us that have neither access to a lathe or PJ's experience, there is a low cost non-destructive alternative - chopsticks. Not good ones. Just the small cheap soft disposable types.

 

[crazypj]

You haven't seen some of the carbs I've been sent for modifications

 

[teazer]

Good point.....

For driving out the needle jet?

Do I need to replace the needle/needle jet? Also I assume if the float valve has a groove in the taper then I need new ones?

 

[neevo]

Done a bit of reading and looking like I might try the following with the 466 kit and free flowing exhaust:

38 pilot
85 or 90 mains

I don't see needles/ needle jets mentioned anywhere, what's your option on those PJ?

 

[crazypj]

Start with stock positions.
I thought the 466 needed a 102 main? (I used 105'sin the 490)

Unfortunately I don't have stock as the carbs were from a 350F.

 

[crazypj]

350 needle and needle jet should be OK.
Use middle groove and adjust from there if you need to

 

[neevo]

In the 350F carbs I have is:

35 pilot
92 main
18234 needle (middle clip)

Haven't pulled the needle jets yet (probably won't at this stage). Just checked the brass float needles and whilst there are marks there isn't anything I can feel with my fingernail.

So will try:

38 pilot
102 mains

Cheers PJ!

Just on jetsrus.com trying to identify the pilot and mains (in the sofa with the calipers) and not having much luck

Pilot is:
28mm length
5.5mm main body
3.4 thread
2mm tip

This matches nothing they have on the list of pilots.

The main doesn't match any of their pics either. Anyone know what the type of mains/pilots the 400F takes?

Edit: found them, google took me straight to a page for the 400F that I couldn't find from the main page.

Pilot: 99124-076
Mains: secondary mains 9.6mm x 6mm (no part number)

 

[crazypj]

I though 350 had same 'push in' jets as 550, 500, etc?
I'll have to open up mine and take a look

Dunno mate! Never seen the other carbs.

The main jet is press in and the pilot (slow) is screw in.

 

[crazypj]

OK, they are the long screw in, I know the ones.
They are also used on the 2000~2004 CR250 plus gazzillion other Kei-Hin carbs
When you said primary I was thinking of 3 jet carbs (which350/400doesn't have)

I called them pilots, is that what did it? Looking online looks like there are slow and main jets. Then the needle.

Jetting is bloody confusing! Looks like 466 kit users are all over the board. 38
- 40 slows and anywhere from 80 - 100 mains. Arrrrrrrrgh.

 

[crazypj]

I've been up all night again, back playing up (surprisingly it's much worse laying down?)
Only reading every other word or so. :
Guess I should read properly before replying ;D
Use a x10 loupe for checking parts (get cheap et from Aussie version of Harbor Freight)

 

[neevo]

Sorry to hear that bud! Thought it had calmed down in recent months. Got any drugs?

 

[crazypj]

Doc told me I shouldn't be self-dosing with the various meds, does nasty things (like destroys liver and kidneys)
I'm finding out a lot more than I ever wanted to know about what you can take and what you can't with over the counter pills.
Really surprising, 10 grains aspirin and 1000mg paracetamol (together) is working almost as well as Naproxen or Etodolac, I've probably built a tolerance to them? (not as good as hydrocodone/paracetamol mix though)
I feel a lot better when I take everything together, there's no pain for 5~6 hrs, I try not to take the concoctions more than twice a day (double what the directions say for a 24 hr period)
