  1. This forum needs more info on the hs 142 engine. I would like to see a sticky that deals [ not sure how this is done] with this engine since I can not find a detailed repair manual for the 142. I looked at the honda manual and found that it is just the manual that comes with the engine and it only has info that relates to starting,oil change and other basic stuff. So a sticky would be nice for members to post detailed photos of 142 engine and carb repairs and techniques. My request deals with intake and exhaust valve remove and replace. Question---how do you remove the valves.What kind or brand valve spring compressor is used or a jerry rig method for valve spring compression

    you dont need one. the springs are soft enough to remove the retainers with one hand. the other hand is stuck in the cylinder holding the valve up...

    or support it on a piece of timber, freeing the other hand....whatever. :)
