For the rest of you on the net who may be using a VW engine. I experienced the same problem. However, with my 1835 and 1915, I did not have the problem, but when going to the 2180, the temps were much too high for my satisfaction. I tried everything and finally found the solution. I use the Revmaster cooler mounted below the engine case and fed from the front. I showed this solution to a friend who was having the same problem. He implemented it and the problem was solved. My engine is now a 2276 and my only problem is that the temps are too cool, but I can easily solve that one with Mark L.'s solution of the Earls Sandwich adapter temperature control.
Check out the picture on the Revmaster site. http://www.revmasteraviation.com/ Revmaster is a great source for some items and information, and the engine on his front page looks pretty good also. See N64KR at http://KRBuilder.org - Then click on the pics See you at the 2010 - KR Gathering in Richmond, Ky - I39 There is a time for building and a time for FLYING and the time for Flying has begun.
