Ok 5 weeks in to the "is this worth saving" of my 83 FJ60. Rebuilt carb, checked timing x2, checked/replaced hoses x4, Replaced EGR gaskets, tightened manifold bolts to spec x2, cleaned everything I can reach and I am STILL at 5-6inches of vacuum at 6250 ft altitude. Engine will start and run but stumbles badly and stalls until it is all the way warm. When warm it runs to 10-11 inches of vaccum at about 1600rpm and maxes out there. What is large enough to cause me to be losing about 2/3 of my vacuum? Is my only option left to pull the manifolds and check for cracks? I am not afraid to go there but not something I look forward to doing if there is any chance I missed something obvious. Ask away if you like, I am no genius just amazingly persistent....haha! Thanks fellow cruiserheads this crap is addicting........gotta go mow the lawn before it blocks the windows......coming dear!!!!!
