Looking for operator's/owner's manual? Illustrated parts list? or like a real service manual? Any particular models?

Looking for a real service manual for a Homelite Trimmer:
Model # UT20779

And Ryobi Brush Cutter/Trimmers (service Manual):
Model #: ZRRY30570
Model #: ZR30004

I am doing port work and need torque specifications, clearances etc.

THANK YOU!!!! That 3rd link had a general specifications page with torque specs etc. I can use that for Ryobis too I am assuming.

Ahh, ok, I got ya. Wasn't sure what kind of info you needed.

Torque specs on all those little engines are going to very close. The fact the sequence of bolts are all torqued the same means a lot right there, even if the torque is off spec a little.

Thanks man for getting those out for me. Now I am fearless. Going to slight port matching and boring on the exhaust and intake ports the 25cc and 30cc brush cutters and mod the daylights out of the 25cc... why..? Just because the muffler mod and carb adjustment did so much. I want to swing some big line and get through the back woods with both that and the brush cutter. My back 3/4 intimidated me before -I was thinking no way they'll go through that mess...Now I am thinking now way it can stop me. HAHAH.

Thanks again!
