New Carb Tips

[Green Mesa XJ]

holy crap there's still a supplier for that part!

Far as where it goes this diagram of the lines should help, you can see there's is a lot of crap you don't need really. There is a way to make you own canister too. I'll post the link if I find it. I'm also going to try to attach the PDF of the Weber k490 instructions, I think you must be missing them from your kit.  The instructions are available freely online from the manufacture so I hope it is not problem adding it. If it is I'll delete it immediately.

. Page 3 described the location of the lines and purpose for the original carburetor. Page 4 has the step by step on which lines to use and how to attach them to the Weber 38, page 7 & 8 have images of Weber carburetors

so i should connect it to the "carb bowl vent"

which should be the middle one (does it make a difference if i connect it to the top or bottom port )

 

thanks for the PDF my kit did not have that one

I'll look at mine tomorrow afternoon and see how it goes, I think it only fits one way if trying to do it OEM, but you ought to have a lot of options if you get creative.

in the diagram picture you posted 

the arrow that points to (PURGE SIG) is that the bottom port

and (CANISTER PURGE) is the top skinner port 

 

also the throttle and tranny cables on the carb 

how do you have yours connected ?

is yours a automatic tranny like mine?

[Green Mesa XJ]

No mine is a 5 speed.
Is there a kick down cable for the 904?

yes there are two cables 

one for gas 

and one for tranny 

[Green Mesa XJ]

I can’t tell from the pictures but the should be three mounting points on the throttle, outer most is for the spring that attaches to the valve cover, top inner is throttle, below that is kickdown cable. Basically the only way all that will line up with a factory valve cover brackets.

this guy did the Weber upgrade on a 86 MJ with automatic, in some of the pictures you can barely see how his throttle set up is.

yes but unlike him i will get the original air filter to fit on there much neater

rather then just banging the crap out of it with a hammer like he did
