Haha Tyor....I see you couldnt resist the opportunity to open it up and have a look! :-)
Ok so from that pic, it looks like the lower nipple on the manifold opens up to the carb pump, but it also looks like it goes through to the manifold as well. Maybe thats how they are getting the reciprocating suck/blow action on the diaphragm. Very cool that it works because yes, the Saito gassers are converted glow engines and as such, dont get the same lube. Hence the high oil ratio.
Thanks for making the commitment to open it up and show use. I like the design and think that if the materials are of a good enough quality, it will make a more reliable runner than the Saito's.
