Most of don't complain about having a BIG one. But you?...

I have no idea, I am a carb virgin with plans to change that soon. Anyone???

Right... so, i have completely fubard one float needle seat, it just wouldnt come out. All 4 main jets have no number whatsoever, im about to pull the pilots. Im also missing some kiNd of jet here, the left hole... oh stop.

Not that pics show on my phone too good, , but I think the big one is the correct one

so, the big float needle is for gravity feed, which i have. I swear, there is no fuel pump on my bike.. if the valves are as jacked up as the carbs its a wonder the thing runs at all. Now, I need to order, what exactly, from our west coast friend? This is my only vehicle. I have use of an alternate for 3 more weeks (old ass f150, long bed, 16mpg) Help!!

If it helps in any way let me add this. I have just installed a set of carbs from a fuel pump FJ jetted for UNIs on my 86 gravity feed FJ. I adapted the 1 into 2, 10 mm fuel line (84 to 87), to 1 into 1, 10 mm to 6 mm, with smaller metering valves. I consulted with Randy and he mentioned that a few others have done this with no real problems. Not tested yet by me but I will be testing tomorrow in the humble hills known as Angels Crest Hwy. I will also get some 75/80 MPH sustained speeds to test the feed rate of the implied reduced flow. Randy knows his stuff so I feel comfortable giving my FJ the WFO test.

San Dimas Mike, up for a visitor?

as long as you arent running from the police.
I have put enough $$$ in at the pump to figure im getting about 20-25 mpg. I would LIKE to get double that, but i have k&n pods that i will be switching out with UNI-s soon. but first, let the beast breath and drink freely. as in, its a 580lb doorstop till i hear back from randy

 Okay...I cannot see the needles or e-tube well enough on my cell.

Since you have curved slides you need the 86 1200 kit. That will replace all of the worn parts as well as incorrect parts you are looking at.

Yes that casting hole is supposed to ne on the carb.

thanks randy, order is in.

Okay, I am home and the photos are a little bigger, but I still cannot see the needle very well. But it does look pretty blunt at the tip which indicates an aftermarket needle.

There is a bleed jet is missing from that carb, is it missing from all of them?

The jet on the other side looks suspect as well. That jet is supposed to be a non-removable jet that is normally recessed into the hole. By the photo you can see the brass jet/fix orifice actually protruding from the center two carbs.

The needles & seats are the same dimensionally with the exclusion of the fuel supply hole, the body & needle are the same. I am not sure what someone did there if one needle is larger than the others. Someone found something from a different carb that would work.

That is the curved slide, shrouded e-tube. It is dirty but still looks to be stock brass.

Get the crabs all torn down and get some good quality & clear photos. I need to be able to see that fixed orifice jet that is protruding and see if I can determine why.

ok, got them totally apart. Fuel T fitting and drain o rings are hosed as expected, but the carbs arent all that dirty inside. which is good. Now just waiting on the mailman i guess.
Randy, are those pics enough? Only the one carb is missing the pilot jet, the rest of them are there.

[Flying Scotsman]

That is not a pilot jet thats missing its an idle air jet.It adjusts the amount of air in the Air fuel mix.
As far as the the jets sticking up out of the carbs thats not normal they are usually pressed in fairly deep I wonder if they are still in there and they have tried to add a seccond restrictor.Andy might know

Now i want to pull one out. I have sprayed tyem all through with cleaner, no occlusions.
