spokanesoob Posted November 17, 2007 Share Posted November 17, 2007 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 Link to comment Share on other sites More sharing options...
TheSubaruJunkie Posted November 17, 2007 Share Posted November 17, 2007 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.

Loyale 2.7 Turbo Posted November 18, 2007 Share Posted November 18, 2007 ... ...there was too much tension on the throttle cable. ... 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! Link to comment Share on other sites More sharing options...

TomRhere Posted November 18, 2007 Share Posted November 18, 2007 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.. Link to comment Share on other sites More sharing options...
spokanesoob Posted November 18, 2007 Author Share Posted November 18, 2007 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? Link to comment Share on other sites More sharing options...

spokanesoob Posted November 21, 2007 Author Share Posted November 21, 2007 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 Spokanesoob aKa Jordan Link to comment Share on other sites More sharing options...
GeneralDisorder Posted November 21, 2007 Share Posted November 21, 2007 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. GD Link to comment Share on other sites More sharing options...
