What do I need to block off or disconnect to just run pre mix fuel, any help Thanks

 

You will need to remove the clutch cover. On the end of the crankshaft there is a black plastic bow-yie looking thing. Pull that off. You then block the line going to the carb.
Service the clutchs while your in there.[img]i/expressions/face-icon-small-wink.gif[/img]

Torco GP-7 (torcousa.com) is the best oil (IMO)
Klotz R-50 is another great oil.
