yeah.. deffintely rude.. I agree with the other poster.
i know you want a yes no answer.. but .. if it really is advanced all the time.. I would expect harder to start conditions.. and at least a dragging starter eventually.
It takes mere moments to visually inspect a mechanical advance.
if you are afraisd to do that.. or don't know how.. just ask. Simple inspection / observation won't 'hurt' anyting, even if you chose to leave it that way.
Some are telling you that you will use the tractor at full throttle all the time.
that may be true.
it's not anywaher near true for me except when mowing. the other 50% of the work i do on a tractor is not at max throttle..
