subarurx yo Posted March 9, 2012 Share Posted March 9, 2012 im dealing with a 85 ea82 carb wagon, it backfires while cranking over and wont start and ive triple checked cam timing, firing order and set dizzy where rotor points to hill holder at 0 degrees and tried on center of the three marks on flywheel. it also has delta cams in it and remove egr stuff, was a smooth runner until i changed the block and did a full reseal ive put together a ea82t 4 or 5 times without this much problems Quote Link to comment Share on other sites More sharing options...
Robert Harik Posted March 9, 2012 Share Posted March 9, 2012 Can't think of anything but valve or ignition timing. Quote Link to comment Share on other sites More sharing options...
MilesFox Posted March 9, 2012 Share Posted March 9, 2012 you might have the firing order off. Typically, if #2 and #4 are crossed, you get a backfire at the throttle. rotation is couterclockwise 1,3,2,4 with #1 being the closest to the clip on the back of the cap. Double check the timing belts. At 0 deg TDC, the cam sprockets will be pointing at the hard edges of the valve cover, with the passenger side pointing at the bottom edge. I am only explainin:burnout:g this since you mention you had the engine apart and back together. Quote Link to comment Share on other sites More sharing options...
subarurx yo Posted March 9, 2012 Author Share Posted March 9, 2012 I'm certain the cam timing is on I left the shrouds off also so I can see what's going on I'll mess with firing order tomorrow Quote Link to comment Share on other sites More sharing options...

fixingrusinc83 Posted March 18, 2012 Share Posted March 18, 2012 you say you have double checked timing but if your book or manual is wrong it will be wrong 100 times. So not to question but one side will be at 0 degrees or 12 oclock and the other will be at 180 degrees or 6 oclock have corrected dozens of these that owner was working out of this or that manuel. Only trying to help. Quote Link to comment Share on other sites More sharing options...
