Overview
'74 2.0L, 20K miles, stored since '84, first run Oct 2018. 100% stock D-Jet engine with new hoses, fuel system, etc. Spec compression on all 4. Dwell set, timing set. Engine runs good, strong - chasing idle problems (see my post 'idle weirdness'). My question is; how good can I get this engine to idle? Can this engine run smooth at 800-900 RPM with very little engine vibration? Can the engine run rock steady at 800 rpm without minor surges? Currently this engine is shaking at idle, not violently but you can feel it in the cab. Does anyone have a high quality audio example of this engine running when new? Or to absolute factory spec? (yea, I know many of you believe that this is not a good method of reference, but hearing what one SHOULD sound like is helpful). I look forward to coming into this group of like minded 914-crazy (me being the most crazy) group of awesome people each day. Many thanks in advance CTC911CTC |
