Never seen anything like this

[440ex. ehhh!!]

I took my carb apart earlier to see what jets were in it, and this is what I find.
Is there a reason for this?
My 05 didn't look like that and it rubs off by touching it.

I have a 208 main, and the other 2 jets I am not sure about.
1 is a 75, and the other is a 50...Which one is my pilot jet? The 50 is my pilot correct?
I researched and saw that "Scro" has never touched the starter jet in his, so 75 is what everyone should have, no?

[01boneless]

wow! ive seen it alot before that happens when the carb has set for a long time with gas in it (todays gas gums up bad) also see how the bowl seal is starting to dry wrought. your best to get a rebuild kit

[440ex. ehhh!!]

What do you mean dry wrought?
I thought maybe the colour was from having klotz gas run through it, but i guess not :(

[slainwarrior]

i had a similar problem after letting my quad sit for months.. im pretty sure its from the ethanol they add to the gas now, if your not running pump gas then im clueless.

[Baileygunns]

That's bad gas, Josh...

Soak that thing in carb cleaner and clean it out real good. Unless your Dad has a hook up at work with a dunk tank or one of those fancy sonic parts cleaners. Get all the orings out of it before soaking it, the solvent will kill them. Put some compressed air to all the passageways, pull out the fuel screw and clean in there too. I've seen a few bad ones but that one is REALLY bad, lol.

The 50 should be your pilot, it wouldn't run on a 75.

berryman carb cleaner or yamaha sells a carb dip. Soak like bailey said.

[440ex. ehhh!!]

Okay thanks.
He's got a parts tank that is basically just a washing machine with a rack in it and blasts hot water and soap in it...It get oil, grease, and everything off of parts. I would still have to remove all the seals and gaskets to run it through that right?

[Baileygunns]

Yup, pull the seals out. If nothing else, it will keep you from losing them and you can check them all for cracks.

How was it running? Didn't you have it out the other day?

[desratt]

Count the turns on your screws if you mess with them

[fomospede]

ETHANOL for sure

search EOFUELS and find a local station that provides ethanol free fuel use it in all you gas engines and life will be better

[440ex. ehhh!!]

I just bought the quad a few weeks ago, and before that it had just finished being put back together.
So it is for sure because the kid left all the gas in the carb for about 2-3 months without touching it

[440ex. ehhh!!]

It was bogging down at about 1/4-no throttle. It also popped on decel a lot

[440ex. ehhh!!]

So heres another problem I have.
I know you guys probably do not know Celsius for temperature, but I'm Canadian so thats what I'll be using. lol
Generally, 0 degrees Celsius, is 32 F.
Also, 25 degrees Celsius is 80 F.

208 main jet and 50 pilot

The bike was jetted at aprox. 15 Celsius and ran perfect.
I started it up when it was aprox. 10 C and the header was glowing red, which indicates it was running lean.
I understand that.

But heres the thing. I went riding last weekend, it was about 20 C (75 + or - ) out. It ran good for the first 15 mins i was riding.
I stopped and when I went back out 2 minutes later, it started bogging down at very little to no throttle and eventually cut out.
So to me, this means it is rich.
It ran fine when I gave it more throttle though....it just started popping on deceleration.
I turned the screw on the left side of the carb out 1/4 turn and it helped the bog and popping a little.

So I am lost with the jetting on this bike. I don't have any jets to put in and see what happens, so I need to know what to order and where to start.

Any help guys is greatly appreciated.
I have tried searching but nothing has really helped...
One second I think it is rich and another it seems lean.
Ugh...

[Baileygunns]

Get that carb cleaned up first... Then see what it does.

[440ex. ehhh!!]

I sprayed the whole thing out with brake cleaner last night, and I still had to wipe the yellow off of it...

[chronicsmoke]

Hey man, I'm in Ontario too, I'mat a 185 main/50 Pilot at around 100' above sea level..

[440ex. ehhh!!]

Going by your signature you have an 05.. I'm talking about a 2008

Touche, I forgot you unloaded your 05 for the built 08..

[440ex. ehhh!!]

Not to worry.
But I really need to figure this thing out.
I have my first race on the 25th and I was going race at an Obstacross next weekend if I could get it running good

[Baileygunns]

You sound rich... Remember the FCR carbs take smaller jets then the stock 04/05 carb. I run a 198 main and 52 pilot in my 05 so you "shouldn't" be more then that.. Also, if it ran good in that cold of temps it's going to be to fat for the warmer temps... You fatten up for winter and lean out for summer, cold air is more dense so it needs more fuel. Do you know who did the head work? Might be worth an email to find out what the porter would recommend for a base. "Usually" ported heads drop jets sizes because of the draw, they pull more fuel through a smaller hole.

[440ex. ehhh!!]

Yeah I realize it should be rich, but I was reading up and found that popping on deceleration meant lean.... It really confused me.

The head was done by a local shop that builds stock cars. It is a very well done head, I think better than the bigger companies. Place is called New Generation Engines. No website.

Also, with how gummed up that carb is I would almost guaranty there's junk in the pilot circuit giving you the lean condition on start... Doesn't matter how big of a pilot jet is in there if the passage is clogged.
