The Engine War

The 30cc Sbach engine runs, but it doesn't run smoothly, 4-cycling a lot despite multiple attempts to tune it, even resetting the Hi/Lo to factory and starting over. Today I replaced the large admission  valve between the carb and cylinder, and all the gaskets and diaphragms in the DLE/Walbro WTA carb, and then getting the engine to start bone dry. That took f-o-r-e-v-e-r, and once I got it started I had to go back to scratch on the tuning. It still 4-cycles more than it should, but I think I have a reliable idle and max full throttle power. I am tired of fiddling with it, so to make my point I put the cowl back on.

The carb rebuild was easy, and there is a great video here. I didn't mess with the pin under the spring thingy.

Tomorrow, fix the damage one of my darn cats chewed into the right horizontal stab... then fly the thing!
