Dear kevarc,
I have also sent my brand new engine back to my reseller.
After burning more than 3 liters, my FG90 was only still running on cylinder #1.
The cylinders #2 and #3 never got running and stayed cold.
I never seen such a behavior during my 40 years experience with many brands of engine.
See below the answer of Saito Japan given by my reseller !
Dear Sirs,
Good day!
Thank you for your e-mail.
We have also watched the video.
It is normal and not defective. Not only FG-90R3 but also all 3 cylinder engines are the same.
Usually the 3 cylinders do not run evenly from the beginning. And also each temperature of
the 3 cylinder do not rise evenly from the beginning. At the final adjustment of engine,
the 3 cylinders run evenly and rise in temperature evenly.
Would you, therefore, please run the Engine more than 1ℓ. And then, turn the main needle
CC(clockwise) to achieve peak. If the cylinder #3 still does not run after the procedure,
please replace the plug with new one.
We hope that this information will be helpful.
Best Regards,
Saito Seisakusho Co.,Ltd.
Best regards,
Alain disappointed with his first Saito engine
