Greetings guys , and please excuse me if this has been covered before.
I'm new to 4-strokes. I do have a [factory] Saito 56 in C/L guise. After my usual very careful running - in process I'm now test flying.
I had been advised to run my Saito with muffler pressure to the uniflow tank. [ Connected to the uniflow pipe of a Brodak metal tank ].
I was using a 13x6 prop' , 20% total lube' [ 18% synthetic / 2% castor ] with 5% Nitro'.
I couldn't get a decent needle setting on the ground , it 'burbled' and stopped after about 30 seconds.
I took off the pressure tubing. Set the needle at it's usual setting , around 2 and a half open.
Started her again , no problem ! Tuned to give a tad rich 8,400 and it flew in a solid , reliable typically Saito run !!
Happy Days !
So guys , is it pressure or no pressure ....That is the question ? Sounds like Shakespeare's Hamlet from school days !
Maybe it's just my engine. Any contributions will be much appreciated.
Robin.
