I'm GLAD you did!! More info on the electric 2-speeds is MORE than WELCOME!! Sounds like you may have a small leak,somewhere in your "return" line. With the engine idling,(in Neutral,wheels chocked),spray each fitting with "WD-40".Don't forget the circumference of the "pancake"). Listen for the engine to increase R.P.M.'s slightly. when you hear that,you found your leak. If that doesn't work,you may have to replace your diaphragm. Just follow the instructions. I had FUN doing mine! Hope this helps.
