I sent it back to PST and they adjusted the pump and sent video of it working on thier test stand. When I got it back, I reinstalled it into my shokjet and no luck. The video is from the attempts after the return from PST. PST has been very helpful through email but nothing has worked. I have tried about everything. I removed it and put it in a test a stand. Tried different levels of propane but never tried turning it off at 15k. I was able to boost the turbine with a blower through 30k then again at 40k. I could get it to idle then slowly that it up to max thrust and then flameout on the way back down. the ramped need to be adjusted, I am at 7000ft. I tried a 7 cell nicad battery to see if it was the starter. It did not help still had to use the blower. I am using propane with a regulator. It has been very frustrating. I could blame it on me being new to turbine but the person I bought it from was the first owner and has been helping me. He has three wrens and a jet central. He definitely knows what he is doing. We did run the PST on a test stand last fall before I installed it in the shokjet. It started fine for one run. Using the blower will not help in the shockjet. The wing covers where the blower needs to go. I have a bunch of attempted starts. I have learned a bunch. At least know once I get it beyond 40k, it will most likely work. It is just finding out what is causing it not to spool beyond 30k. I will try what you suggested this weekend. If it does not work I will be sending it back to Thailand again. It has been a frustrating summer. I was hoping on getting my turbine waiver but it might have to wait till next spring.

Thanks
