25 year old yardman mower: no start

[rfsmith48]

Hey,

I inherited this mower.

It has spark, and a new spark plug.

From the pull cord tension, it has compression.

With the air cleaner off and the throttle wide open, I have tried to start it with gas and starter fluid down the carb throat.

No Luck....

What else should l try?

TIA,

Rog

Remove and clean the carb, then install a carb repair kit, and make sure to clean the jet in the bowl nut.

check that the valves are moving.
A stuck valve bending a pushrod will also make it hard to pull the cord but you will have no compression.
Take the plug out and make sure that the piston is going up & down
