I finally got my PTE36R engine to run. New in the box it wouldn't start. I reset the timing to 28 degree BTC. Only an occasional pop. I sent the engine back. They found one of the carbon fiber reeds was not sealing. They test ran the engine and sent it back. When I received the engine, it still would only pop but not start. I took the reed cage out and found casting flashing around the reed sealing ports. I deburred the ports and sanded the sealing surfaces with 1000 grit paper. The timing was off, around 40 degree BTC. I reset it to 28 degree. Now the engine primes easy. The HS and LS were off slightly and had to be set slightly richer than recommended settings. The initial reading is 7400 RPM with a XOAR 18-10 swoard prop with stock mufflers. I am using a home made Hyde type isolator mount. It has a reliable idle at 2200 RPM. Throttle transition is good. I had four flights on the engine. It ran very reliably. I hope to get a rear exhaust header and use my ES40G tuned pipe next.

I have a OS GT33 engine with a ES30G tuned pipe on my EF 78" Extra. This is a real power house set up. The OS GT33 has much more compression. It does want to start backwords with the stock OS ignition module. I'd like to get some comparrison data after the PTE get broken in. Below is a picture of the OS engine isolator mount.
