I understand that most people including me don't have much experience with the os 30 wankel, but if you do I would really appreciate help. I recently bought the engine and after a only a couple minutes of running it I hooked the electric starter leads on backwards and turned the engine over. Afterwards it would only start within a couple degrees of half throttle and it would seem to be extrmely lean because it would start to slow down and then stall after only five seconds of running, also the motor will be to hot to touch after just a few seconds of running after a cold start. It is not lean however because it does blow gas and oil out of the exuast. I am thinking that maybe it is a glowplug that is to hot and detonating the fuel to early. I understand that no one will reply to this post do to the situation but if anyone has had experience with these engines I would appreciate a reply from you.

Hi!
The OS .30 wankel runs the same way as any other glow-engine.
As long as it gets fuel and air it runs! Just because it blows fuel and smoke out from the silencer says nothing of the carb setting. Pinching the fuel line isn't my cup of tea. Listen to the engine is better. That's how most people set their engines.
If it gets hot (very hot) it definitely runs too lean.
Running temp for all glow engines is hot! So hot that you might burn yourself if you touch the head of the engine when it runs at full throttle.
So...See to you have adequat fuel (20% castor oil, 5%-10% nitro and the rest methanol).
Glowplug : OS special wankel plug ( I think its called RE), No other plug!
Propellers: 10x6 APC.
Fueltank: 8oz
Tankpressue from silencer.
If you have followed these advise all you have to do is to start the engine at idle (Throttle drum open 1,5-2mm) with the high-speed needle open 2-3 turns from fully turned in ...and when the engine has started ...adjust the high-speed needle for best rpm......that simple!

Also, rotary engines run inherently hot. Hotter than a reciprocating engine.
