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 |

Call me crazy but when you park it for 35 years
You should just be happy it still runs . I would reach into my wallet pull out 3k And do aftermarket fuel injection. If the eratic idle bothers you . Or you can keep driving as is and hunt down exhaust and vacuum leaks Smoker tester (glass bong) is your friend |
