Your TR maybe already configured correctly for your application, but OS engines, (and other MFG's) usually require the Cooling Head to be rotataed for Max Cooling in the Transverse applications. Anyways, check it out, it's worth a shot. Hope this makes sense.
El Salvador - Wow thanks for the great advice. I have had this engine completely apart and never noticed the way the cooling fins are oriented in the head! It is exactly as you said, I need to remove the head and rotate it 90 degrees so that the air flows from front to back! I'm glad there are guys on the forum a lot smarter than I am! I will try that, I am sure it will result in cooler temps!
