RE: saito .91 smoke????
Mods, Very nicely done! I was just looking at that very same pump last nite.
Mike. I hear ya on not wanting to drill & tap a brand new back-plate on a engine. This Saito 100 comes with the pressure nipple allready installed in the back-plate. It the of course has another one installed in the muffler. I read someone else's post stating that a 4-stroke doesn't create enough pressure by themselves like a 2-stroke does. I don't know if that is accurate or not, but I'll be using a pump just to save on the headache factor.[&:]
Thanks for the good advice, to all of you!
Mark
