For the D, it required the connection of the battery charger, getting the car to run, then warm it up, and finally perform the Engine Compression test. All went well and the D will go another race with the motor. Here is the compression results:

From there it will be the odds and end. I would like to chase the balance issue. As it stands now, we can't get the weight to balance up front. The current thought of this cause is excess twist in the chassis. SInce this is not necessary going to buff out, we might be able to chase it with some spring changes. After that, the adding of a roll bar to the cage here, and change of the seat belt there and we will be off to the punch list.
For the Z it is a little different story. When we got to it like the D the Battery was low so another changer was used to help the battery. The next problem was the Le Brea lake under the car. Our oil pan leak has let most of the engine oil to coat the mat under the car. With so little oil in the engine, running the car seemed wrong, so the oil pan exchange is high on the docket.
The second issue we wonted to address is the fuel issue. The symptom that we are fighting is that during the race, when the tank is about half fuel, the car in the left hand turn began to develop a hesitation. Why this problem has started up is the questions. To investigate, the first step was to get into the tank, check:
What we found inside was a mess, like when we opened it on the track. Debris was found in the tank, shown below:
So, we set forth to empty and clean the tank. Here is the image of the first rag out of the tank.
That is a fair amount of debris, so clogging of the fuel strainer, tank transfer tube, and/or trouble with the fuel pump assembly are possible. It will take another weekend to see if we can narrow the cause.
