I have a 1991 520h and I can mow for hours on end until I turn the tractor off and then restart it. The tractor restarts nice and easy warm but when I engage the PTO (mower deck) it slowly kills the engine. If I disengage the PTO it revs right back up. It is an electric clutch. I was thinking if it was a kill switch wrong I would imagine it would kill it a lot faster than allowing me to cycle on and off the PTO. Any thoughts?
Looked on the site (and YouTube) and can't find anything comprehensive about adjusting valves without taking things apart - most are with engine removed I don't want to do.
Can you adjust the valves with engine on by just taking off the air cleaner unit to expose the valve covers and take the plugs out?
Can Top Dead Center be found without removing anything else or does the flywheel canopy have to be removed?
I've adjusted valves on cars, etc and it's easy and straightforward - but I don't want to have to take anything apart that's unneccesary.
