I think I have more links on another computer...I'll post them if I can get to them...

Sorry no .60 manual...I have .61's...

Re guarding your Fuel Starvation situation:

You should be able to use the Diagram for the .45 in this link below for your fuel line connections (I think)..

Take special notice to the Check Valve Orientation!! (Sounds like a likely canidate for your problem)

Do you know the status of the Diaphram?? (Recently Replaced ect...)

Make sure your tank isn't leaking!!...Your fuel system needs to be Air Tight...

Your using an OS #8 Glow Plug..Right??

Needle Valve Open 1.5 turns from closed...

How is the Fuel Pressure Regulator Adjusted?? It should be Flush or "Slightly Protruding(1/16)"...Unless the Fuel Pressure Regulator Adjustment Screw is way out of wack...I'd wait to touch this until you have her up and running...***IF you monkey with this adjustment...Only turn the screw Very Very Slightly! 1/16th or 1/8 incriments are all thats required!! Very Tiny Adjustments***...Once you get her set-Up...You shouldn't have to mess with it...

If the diaphram has been recently serviced....One thing I have commonly run into is the gasket for the Regulator Body isn't cut very well...The Holes can be obstructed if your not careful...I have seen this on All my YS's...I just know to look for this and clear the holes by cutting them larger in diameter before putting the assembly back together...

YS Engines Require Special After Run Oil...People will debate tis...But most common Petroleum Based After Run Oils will ruin the Silicone Diaphram and O-Rings ect...I'll get you a link to what I use...It's costly...But a 8oz bottle will last you a lifetime...You only use two drops at a time...
