Throttle Body install with throttle cable route
I have made quite a bit of progress getting things ready to run.
Besides installing the panel, I installed the Throttle cable to the TB. Fortunately it worked out quite well.
Of course I had to match the travel of the throttle cable to be appropriate with the rotation of the TB butterfly plate so it was close while the knob was pulled and precisely wide open relative to the airflow while the cable was pushed all the way in.
There was certainly a bit of trial and error. Fortunately the throttle arm has several holes on the arm which was very valuable in matching the rotation (of the throttle body plate) to the throttle cable travel ratio. I hope that makes sense, if you have questions let me know.
This is an after market TB. I think it is 70mm. The OEM is a non-mechanical unit which added complexity that just did not make sense to use.
On a side note, the vacuum ports/tubes on the TB have not been capped yet, but will be before runup.
Other tasks completed are:
1) Putting on a new (better} bypass hose.
2) Installing the PSRU (prop gearbox).
3) Wiring the various sensors. I decided to add another water temp sensor as well as a water pressure sensor.
4) Wired up the PSRU oil temp sensor
5) I added coolant.
6) Added the oil pressure sender for the HOBBS.
I am not going to bore you with the "to do" list, but it really is not bad.
