Hi everybody
this is my first post,i discovered this forum only yesterday.
I am relatively new to small engine repair but i love it as hobby, and since i am just retired i will have time to learn more and enjoy myself.

I would request your assistance please!
A friend ask me to check his ariens sierra 1540h tractor, i beleive it has a bad head gasket.
The moteur is a BS model 28Q777-0645-E1 code 981-2227D 15hp ohv vanguard.Could someone give me the valves gap and torque for the head screw.
Also is it adjusted at compression tdc + 1/4 inch
Last if someone knows where i could get a pdf copy of the manual for this engine please let me know
tks
Asat
