Just a cool picture of a whale shark in the Sea of Cortez, Baja, Mexico.
Gumin,
This video is witht the "new block" G-100. We did every test possible. These tests included the following: changing the spark plug, changing the carburetor from the w 32 to a new w 32 to the w 47, testing at 800 meters and sea level, flying the ppg at sea level with 100 kg pilot (me), tuning the carburetor with two very good two stroke ppg mechanics and myself, and tried 3 different propellers. In the end, the best we could do was get the "new block engine to settle in to a maximum 8050 rpm at the temperature of 350 degrees farenheight. Once we got the engine warmed up to 300 degrees the rpms would consistently drop from around 8500 to around 8050. I estimate the thrust to be around 70 to 80 pounds at 8000 rpm. If the engine got to its rated 9400, I would gues the thrust would be over 100 to 110. This is adequate for my body weight at sea level. The Vitorazi 100 puts out this kind of thrust.
The instruments are upside down. However, watch the entire video and you will see the rpms drop as the temperatures reach 350 degrees. Make sure you press the enlarge screen button so you can read the gauges. Also, the gauge on the right is the temperature gauge. It rotates from current temp to highest temp. Pay attention to just the current temp.

This second video was taken approxiamtely one minute later on Steve's back. He went to full throttle, yet this time, the engine only would go to about 6100 rpm.
I can send my original engine back to you with instruments. If you can make it work and run at a steady and constant 9300 rpms then I will be a believer in the engine. Please document it on video. Please make sure the temperatures get up to the 330 to 360 farenheight range and the engine runs for 15 minutes at full throttle and full rpm.
