My 🍔,🏡&👕 side hustles are commandeering my calendar for the next several days, so I will be in and out of COMMs trying to scratch out a living. Wishing you and yours a happy, safe and RV-filled weekend.

6A Build Update (Fuel Calibration)
…PaulvS in Australia
The instrument panel has a Dynon Classic EFIS and the fuel gauges are calibrated by adding 5 litre increments of fuel to the tanks to record the corresponding voltage value from the sender.
The fuel tank senders are the original resistive type from Van's that were included with the Isspro analogue gauges. The left tank calibration progressed OK up to the 20 litre level and the sender voltage changed incrementally, but above this level the readings did not really change. The right tank was a little better, but overall the results are not great and I've ordered some new Stewart Warner senders and will probably need to replace the unused but 25 year old senders as I'm not sure what else could be affecting the readings. There was no change in readings above 50 litres for either tank, due to the dihedral and the float already reaching the top of the tank in the first bay.

RE RV-4 Engine Troubleshooting Ideas
…Tweetr
Can anyone look at this video of trying to start the O-360 on my RV-4 and tell what is wrong with this engine? All troubleshooting suggestions welcome. I don't want to bias the suggestions by telling you what I've already tried. If you post a suggestion I've tried, I'll give you my results.
