Wanted to give an update on my Z134 engine with no compression in cylinder #2. After taking off the rocker arm shaft assembly and having it soak in my parts washer, I noticed that some gunk was dripping out of the bottom of the shaft. Took the shaft apart and noticed inside the shaft and the oil holes were almost completely clogged. Also, after removing the head, cylinder #2 intake valve was stuck closed from carbon and a little bit of sludge. Cylinders 3 & 4 that had the 2 other bent push rods, those were carboned up as well. I figured that after years of running this the oil slowly began to almost NOT get to the rocker arms even though the top of the head had oil. I surmised that the oil not traveling down the inside of the rocker shaft caused the gunk and carbon build-up ultimately causing restriction of the valve movement and thus bending the push rods. Now, I'm at a cross-roads! Do I pull the pan and remove the pistons and push rods, pull the sleeves and clean everything and replace the original sleeves with new O-rings? I did notice under the valve cover there was a bit of froth, not much. Not sure if its recommended to re-use the original sleeves and just replace the O-rings but this engine is very quite and doesn't burn any oil and has decent power.

Today's Featured Article - Earthmaster Project Progress Just a little update on my Earthmaster......it's back from the dead! I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
