Hi,

I was mowing with my 129 (which a few months ago had significant work done to it including a valve replacement and other engine work) and I heard something break - figured it was a mechanical piece underneath the tractor somewhere, but checked and all is fine. When trying to start it, all that happens is the front pulley is turning but there is obviously no compression. If I look through the site hole that is used to check the timing - that part is turning. Any thoughts on what this might be? Obviously, the head has to be pulled to see if the piston and valves are moving. Not sure how much more money I want to put into a 45 year old tractor. I could get a rebuilt Kohler engine for it (have been wrangling over this for the past few years), but just not sure that would be the best decision. If I decide to replace the Cub, any suggestions on what to buy?
