Hi, I just gonna adjust my valves in my T25 , I am in Mexico abd here we have a lot of this tractors, they are so good ...I hope one day you upload a video fixing the turn off compression of the tractor, mine doesn't work any more and I turn it off putting the gas in the extremely minimum!!!
I like your silent video with engine sounds and close-ups and dirty hands. Working with your hands is a good thing, it says that in the bible. Where is tractor made?
Turn engine to piston 1 TDC - see marking at the beginning of the video. Set valve lash on cylinder 1. Rotate crankshaft 180°and set cylinder 2. 0,30 mm on both intake and exhaust valves. Do not overtighten the valve cover nuts.
rahul panwar After adjusting valves started working decompression lever. But bad if you have bad starting then you should change piston rings, pistons and cylinder sleeve.
