Title: Need to borrow. Saito .72 R/C Carb
Post by: Bill Little on December 15, 2012, 12:33:39 PM

Does anyone have a R/C carb for a Saito .72 that I can borrow?  I need to keep the rpm down for so many minutes of run time on initial break in.  Mine is the C/L version from the factory.

Thanks!
Bill

Hi Bill; If it were me I would just block off half of the venture with a stick and run it on the rich side with a fairly good prop load that will keep the rpm down. On the old OS four strokes they said to run them wide open and use the needle to keep them at about 4,000 rpm. That also works well. Do check the valve clearance before running, and after running a while.

Hi Jim,

Thanks.  Looks like that is what I will have to do!
