Hi all ! Got a puzzler here and hope someone has the answer! I have a K-181 that powers my 1960's era "Lickety-Log_Splitter" and has always started easily and ran great. That is until while running a log thru the splitter cut back the throttle causing the engine to backfire. Shortly after it started to run a bit rough and then stopped all together. I found the problem which was a broken intake valve collar )probably caused by the backfire and replaced the collar and keepers and thought that would be it. Now, I cannot get the engine started at all. I have spark from points to plug, gas getting to plug but will not catch and start.I have rebuilt the carb and pulled the flywheel to check if I sheared the key but all was good. Sooooooooooo.....tore the engine apart thinking I would find something broken (camshaft, govenor gear, etc. BUT all appears to be in great condition. I have not started to put it all back together yet as NOTHING has been done or found that would help me fix the non-starting problem..........ANY THOUGHTS would be highly appreciated !! The camshaft, crankshaft, gears, seals,etc. all appear to be in excellent shape with NO signs of wear , chips, breaks, etc. I'm going to get a new govenor gear anyway but do not think that is where the problem is. Hope someone out there has some better insight on what the problem can be....I'm stumped !!
