Sorry, I have no personel experience with the 2SE so I can't help there. You have a vacuum gauge which is an invaluable troubleshooting tool. Have you used it to check for problems such a burnt valves, vacuum leaks, etc? There are a number of web sites like 'Holley' which will assist in learning how to use the vacuum gauge to troubleshoot the engine. I also recommend you visit the Stovebolt.com site. Look at the engine section under forums. Do a search for engine problems using words that discribe your problems. You will find plenty of reading. If that doesn't put you on the path to happy motoring post a question. Stovebolters will jump on your problem "like a duck on a junebug". I guess technically our 250 engines are not stovebolts but they will still consider you part of their family. Good luck.
