Simplicity Regent Won't Start
I have similar problem to post regarding a Craftsman tractor, only mine is a Simplicity Regent with a 14 HP single cylinder engine (28P777-0641-A1).
Machine was running fine, was turned off for a minute then I could not start again.
Upon advice from another posting forum I tried rebuilding the carb, and when I wasn't able to remove the main jet (it would not back out of the seat) decided to bite the bullet and purchase a new carb.
Have also just for the shear fun, replace the armature and spark plug.
Have verified that I have spark.
The carb does get wet when engine cranks, but I'm not entirely sure the pump is working 100%.
Checked seat switch; using Ohm Meter. it's working correctly.
Compression looks dicey. I couldn't get a reading using a compression test tool, and I also tried putting a finger over the spark plug hole to see if I could feel a transition (pushing or pulling) when the engine was rotated, but felt nothing.
Valves seem to be going in and out, although I noticed one of the valves does not compress as far as the other. Have tried a number of different valve clearance settings.
Checked the cam key; it's perfectly straight. Went to trouble of pulling the flywheel to make sure, but it was completely straight.
When I crank the engine I get no puff - apparently no ignition. During all my work to try to fix this hunk-o-junk, at one point I would at least get a puff, or cough and occaisional backfire. Doesn't even do that now.
Any other ideas? What are common reasons for compression failure?
Thanks for the help guys!
