Bench running is a good way to kill an engine. Do not hold max rpm for more than a second or two and allow the engine to idle and cool before shutting it down.
Bench running an engine is a very good way to learn how hot an engine can run before terminal failure.
Your temps should be around 200 degrees running at 3500 to 4000 rpm on a smaller prop than normal. Adjust the carb ritcher to cool the engine. More gas = cooler metal parts but higher exhaust gas temps.

The engine sitting there loaded to the max spinning a prop is performing to its maximum ability. Be easy on it.

Follow what Altavillin has sad, but I think you need to re-adjust that gauge. My g26 would never come close to that on the hottest part of the cylinder no matter what I did to it on the ground. They just run cool, or at least mine did.

Try taking the temp while engine is running. After shutdown a false reading can be had from heat dissipation from exhaust area. Capt,n
