well it took me a little while but finally got a weber on my 87 hatch. started it up and nearly woke up the whole neighborhood. oh well it was because of the 4k idle so i have a dumb question which is the idle adjust screw and anything else i should check that would make it have such a high idle can't really work on it anymore or else i might have the cops knocking

did you connect the throttle cable? If so, disconnect it and see if the idle drops.

 

When I installed my weber, it idled at 4k but thats cause there was too much tension on the throttle cable. I had to bend the cable bracket alittle to relieve the tension.

right on i i just put my new weber on too. im stoked to fire it up but i have to put my new exaust on it first :-p .

Yes, it could be the Main Reason, but Also you can Consider that There´s an Adjustment Screw at the Carb´s Base of the Accelerator´s Plate (Where you Hook the Cable) and other cause of a Higher RPM´s is Vacuum Leaks.

 

Check it Carefully.

 

Good Luck!

well got the idle prob. fixed its semi-drivable but it falls flat on its face if you floor it it goes up to 4000 and just bogs after that i have no idea wich screw to adjust can some one help me with a diagram or directions? ive tryed adjusting some of them but it doesn't help at all

No screw to adjust for anything above say 1,200 RPM. There's just idle speed and idle mixture. More likely you have a fuel flow issue as in a dirty filter or your pump isn't putting out enough flow. Could be wrong jets, or float level adjustment too..

 

The Weber flows more air, therefore more fuel, than the stock carb. Your fuel system may have been capable of staying up with the stock carb, but not with the Weber.

 

Just some "of the top of me head" ideas..

does it matter that it only does it under load?? what is the float sopose to be adjusted at? and where is a good starting point for the idle mixture screw?

starting here is your best bet.if you still don't have luck give me a call. i have more time during these seasons. cheers, brian

thanks alot if i can't figure it out i will let you know

thanks again

well i followed the instructions got it working it still had a little delay under WOT but i adjusted it some more to see if that would help and now i screwed my self over so im still trying to figure things out. this is gettin frustrating its gonna be worth it though

well i figured it out I have to have the choke adjusted so that it stays almost closed all of the time cause i am asuming its running to lean does this mean i have to rejet if so wich 1 and what size do they need to be and does anybody know where i can get some? if not on here like in the spokane area

 

but i rather get them from a local board member.

thanks for the help

a very frustrated

Check your jets to make sure before you buy more. You should have (you'll have to remove the top cover to check them all):

 

140, 140 Mains (bottom of the float bowl)

160, 170 Air Correctors

45, 50, or 55 idle jet(s). (anywhere in that neighborhood will work once adjusted)

 

The rest don't matter so much. The emulsion tubes are pretty standard as are the accelerator pump jets. Nearly all Weber set ups use similar jets for these.

so if my jets are right when i check them tomorrow what should i do next?
