pyro926 Posted November 30, 2007 Share Posted November 30, 2007 Ok, I bought this beast (86 gl) with a webber on it. I did NONE of the mods to this car. It seems to diesel about half the time when I shut it off. It also bogs down/cuts out at WOT in 2nd gear. I know absolutely Jack about adjusting these engines/carbs. Is this normal? How do I adjust the mixture? (noob<----------ME:dead: ) Thanks again...... ~G Quote Link to comment Share on other sites More sharing options...
Nug Posted November 30, 2007 Share Posted November 30, 2007 Dieseling can be caused by overheating, advanced ignition timing, glowing carbon in combustion chamber, and most commonly, idle speed too high. Does it idle around 800-900 rpm? It should. Hesitating at WOT is can be caused by fuel starvation. Check fuel filters, fuel pump output, float level.

hatchsub Posted November 30, 2007 Share Posted November 30, 2007 Here is a link of how to adjust your carbs fuel/air at idle. This may help you out some but there might be more going on than just this being out of wack. http://redlineweber.com/html/Tech/carburetor_set_up_and_lean_best_.htm If that doesnt solve it check for vacuum leaks around the base of the carb and intake manifold. They will surely kill your performance. Also do you kno if that carb is jetted for a subaru or not? If not you gotta rejet it so that it will run correctly on your engine. In fact this is the question you must kno first. If you got any more problems you can ask me. Ive been fine tuning mine for a bit now and think i finally have it good. Good luck.

pyro926 Posted January 3, 2008 Author Share Posted January 3, 2008 Would a float out of adjustment cause this? I cleaned the carb, replaced the fuel filter and i'm getting 2.5-3 psi of fuel like webber said I need. Still stuck on this issue. Quote Link to comment Share on other sites More sharing options...
Frank B Posted January 3, 2008 Share Posted January 3, 2008 After double checking all the proper settings and making the correct adjustments, you may end up needing an Idle Stop Solenoid, http://www.webercarbsdirect.com/product_p/43914.060.htm . It stops the fuel flow after the ignition is turned off. Quote Link to comment Share on other sites More sharing options...

GeneralDisorder Posted January 4, 2008 Share Posted January 4, 2008 Dieseling is normal when the Weber is installed by people that have no idea what they are doing. On stock engines, there really should be no need for an anti-deiseling solenoid. Mostly those are useful for race engines that have mixture settings designed for WOT most of the time. Idle mixture, idle speed, and timing are the key components. If these three are correct, there will not be any deiseling. Bogging in second sounds like the carb is having a hard time transitioning from the idle circuit to the main circuit. Possibly the accelerator pump, or a vacuum leak near the throttle shafts or carb base. Could be a lot of things really. If you want to sort it out, you'll just have to learn about Weber's and probably end up redoing the install if not tearing the carb down and putting it back together *correctly*.

pyro926 Posted January 4, 2008 Author Share Posted January 4, 2008 does anyone know what jets should be in a webber on an ea82? (and I did replace the plugs) Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted January 5, 2008 Share Posted January 5, 2008 Stock Weber jetting for street engines... 140/140 mains 160/170 air bleeds 50 or 55 idle jet(s) GD Quote Link to comment Share on other sites More sharing options...
