Valve settings on a AG3-152

Got everything adjusted, timed, gaped, ect. Next step is to set the valve clearances, and check to see if I have a stuck valve.

I am asking for the valve clearances on this AG3-152 Gas burning Perkins. Maybe someone has done this and can give a few pointers on this neat 1967 135 MF.
Thanks in advance;
Boowah
 

Here is the info on adjusting the valves from the service manual.

You can down load a copy of an Operator's manual at:
https://www.manualslib.com/manual/984086/Massey-Ferguson-Mf-135.html

Massey Ferguson publication 1448813M1 is the service manual in packet form (all the pages, no binder). 1448813M92 is the number for the same service manual in a binder from MF. You likely can find used originals of one of those service manuals on eBay.
 
Thanks Jim:
That information came at exactly the right time. I just took the as found readings right before dark. I could see where the
lifters stopped on their way down by the shiny ring around them where they work up and down traveling thru the head. That is
where I took the readings. I took them twice and they repeated.
Starting at #1-.019, #2-.036, #3-.025, #4-.018, #5-.018, #6-.046.
Can't make this up. I was able to move each valve and I am certain none is stuck, they all popped back up like they should.

Walked the distributor counterclockwise 2 teeth, set the points to .021, changed the wires to counter clockwise rotation of
1-2-3, adjusted the plug gap to .025. It immediately fired up, but of course there was the popping out of the exhaust,but now I
am prepared to tackle that tomorrow, thanks to your help.

Thanks Again;
Boowah
 
Hello Jim:
I finally got to work on the 135 this morning without being interrupted. Valves are set correctly this time,thanks to you and
while I had the valve cover off I rolled #1 cylinder to TDC on compression stroke and made sure plugs,points, and everything else
was checked twice. Fired right up without back firing. It runs smooth after all the backfiring. Sure is nice and quiet, almost as
smooth as my 8N, LOL

Thanks, Jim;
