IH cub 184 not running when warm

[Tsg]

My cub will start fine. Just installed new carburetor, plugs, wires, electronic ignition and coil last fall. Used it to plow snow in winter and it ran fine. Started the other day no problem but after 15 to 20 min it will only idle throttle linkage working ok, linkage is moving to carburetor. Wondering if anyone was experienced a similar issue and what I should look at next.

Welcome.

Typically a faulty ignition coil.

Several discussions on engines not running after 15 or 20 minutes operation. Use the search function, top right of this page.

One more post and you can use the free, on line, manuals, top left of this page under Quick Links.

Changed coil. Same result. 15 minutes and no power

Next step, I would check the valve lash settings. Should be .015 for all. If that does not help, if you have the parts, change back to points ignition and see if it makes any difference.
