jonas Posted June 3, 2007 Share Posted June 3, 2007 i tried a search and w/the angles of pics i just couldn't tell. do i need to put that plastic 1/4 inch thick or so o-ring gasket type thing thats between the hitachi and manifold back on between the weber adapter and manifold? the adaptor seems a little loose, barely detectable movement. would doubling the gaskets work just as well? or do i need that piece. i thinks i may have tossed it.

jonas Posted June 3, 2007 Author Share Posted June 3, 2007 well, i'm gonna try doubling the gasket. should make it thick enough to stop the movement of the adaptor plate. Quote Link to comment Share on other sites More sharing options...

Loyale 2.7 Turbo Posted June 4, 2007 Share Posted June 4, 2007 To Stop the Adaptor Plate Movement, you need to Drill the Intake in order to make the Bigger Nuts, fit well...

jonas Posted June 4, 2007 Author Share Posted June 4, 2007 actually, on the EA81 they fit just fine. my gasket was too thin so the adaptor wasn't seating firmly. thanks tho. now i just gotta figure out why it won't idle. dies on me. i still haven't switched out the 3 prong fuel filter for the 2 yet, so i'm hoping that will have a positive effect.

hatchsub Posted June 4, 2007 Share Posted June 4, 2007 u might still have a vacuum leak. The base gasket shouldnt have any play to it when you tighten it down (in other words it should seat firm all around). Did you check to see that both surfaces are flat?

jonas Posted June 4, 2007 Author Share Posted June 4, 2007 somethings up. just keep going over it i guess.... the plate is sitting rock solid now so i dunno whats up. Quote Link to comment Share on other sites More sharing options...
hatchsub Posted June 4, 2007 Share Posted June 4, 2007 maybe some junk stuck in one of the stud holes making it impossible to tighten down the adaptor? Quote Link to comment Share on other sites More sharing options...
