I have a 72 914 that I have been working on forever, started a rebuild 15 years ago. A local machinist help me out and somehow the engine that I thought was a little bigger then 2.1L, I now calculate the size at 2366 cc (103mm x 71mm)! It has an electronic vacuum advance distributor and Solex H32/34 PD513 carbs, compression is 150 psi plus or minus 2 psi all around. Engine starts instantly warm or cold, rev's sluggishly but will quickly get to 6000 rpm easily. The issue is it will not idle below 2200 rpm.
What have I missed? |

Phew.
I have returned to Northrop part time after the person who replaced me, when I retired. quit and now the Northrop team has a back log of of stress analysis to do! (Reason for taking so long to post) Anyway, got the engine back into the car and running (forgot why/where the ground wire went on terminal III of the circuit board when you pull the fuel injection) Have made several drives of less then 10 miles each and have seen oil temps in the low 200's F! I am happy for now! Now I am trying to get the heater fan to blow hot air. I have check the fan, checked the wiring in the engine compartment, checked the relays, (had to buy 2) and now I am trying to get the heater control switch out of the floor tunnel so I can check it out (does not seem to be grounding) Any heater experts out there?
