My 1970 914-4 with factory LJet DJet FI ran fine when it was parked about 3 years ago, and when I fired it up to take it to the RRC last September all was well until the first outing. We went around a corner and the thing just died. It smelled horribly of unburned fuel and it was clear that the engine had flooded. This happened again about 5 times on the trip back to Flagstaff from Moab. In each case we were able to get it started again, but it's a real pain to have the thing die when you are right in the middle of passing someone at 70+ mph!

I'm pretty sure that this has to be a loose connection or a wire that has worn through the insulation and is grounding occasionally. In order to make it easier to find, the question I have is what component would cause such a behavior? Knowing that might make it easier to track down where the problem is coming from. Any ideas? I want to put this back on the road for the Rt66 Classic in March.

a quick check is the head temp sensor failure.


I would just change it. The problem is so sporadic the sensor will most likely test good. Also check carefully where the CHT wire goes into the harness, it may be broken inside the insulation there.
