Hi guys,

ive had my Saito for a few weeks but ran it for the first time today, this is my first radial and I'm looking for some reassurance!
i started with the low needle 8 turns out, high 4 turns, it started easily and I ran it between 3800-4300rpm for 1.2 litres of fuel (15:1), after this I began to try and lean out a little, I ended with a situation where the engine runs well up to about 1/2-2/3 throttle then at WOT the revs drop and it seems to lose power, the strange thing is the high speed needle seems to have little or no effect, the engine starts easily but seems to misfire a lot on cylinders #2 and #3

i know this isn't an obvious problem I'm just trying to be as cautious as possible with the engine and I've read a lot that "the low speed needle is dominant", does this mean using it to get rid of mid-high range running problems?

also I pulled out the plugs after 1 litre and #3 cylinder appears to have done no running, it was clean, is this normal for rich run in?

thanks
joe
