Hi guys.My tractor was hard to start and was burning plugs so I decided to do a compression test.Here is the way I did it.
1.I removed all 4 spark plugs.
2.In cyl 3 & 4 I have 130 psi.
3.In cyl 1 & 2 I have 30 psi.
4.Put the spark plugs back in and redo the test on 1 & 2 and still
30 psi.
5.Try the teaspoon oil in cyl and still 30 psi.
6.Seems like problem with valves.Since they are not working on 2 cyl could it be a broken camshaft? I saw a door behind the carburator under the intake and manifold. Is there a way I could see if my valves are working from there? That is my diagnostic. Maybe you guys know something I could try 1st or another way to diagnose my valves. That door is probably stuck there.
Ty and play safe out there.
Zen.
