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,
Bought the weber's wow what a difference. 44"s w/36 vents. Had AirCooled set them up. Made my own pressure bleeder for the brakes out of an old blood pressure cuff and a Costco mixed nuts plastic jar, was able to get the brakes working really well again. Burned out the electronic pick up for the distributor, Hotspark helped me out there, Kuhltek wouldn't talk to me (original distributor was bought from them) What else, finally got the rear of my car leveled out, had a set of lowering springs laying around which helped, but was still 0.625 of an inch different left to right. Machined up an extended nut and added washers to the left rear strut and set the ride hieght to 6.625 measured at the four jack points. Now I am back to trying to get the turn signals working, the turn indicators work it is the dash indicators that are driving me crazy, left one works great right one flashes twice correctly then both flash weakly, out side lights aren't affected?!?!!? But just like people said early on in this thread big motors need bigger carb's, thanks all |
