Yes sir, those are from a odd fire twin.

For odd firing you just time it different but that depends on what crank you have .The odd lobe spacing on the left cam is because they reversed what lifter opens first , this requires you add the spacing difference between the lifters to the cam lobe spacing .

Re: The Saito twin that never was

The 30 used a single cam with only 2 lobes that were shared by both sides, this is the same setup I used when I did my home build 106cc 4 cycle . . But you are correct the saito twins that used separate cams had a L&R side cam .Much easier to make the single cam setup because you can make your own cam .

Re: The Saito twin that never was

The crankshaft would be the real problem ,you could likely adapt the cylinder to reverse the intake and exhaust as many small engines use the same sized valve for intake and exhaust .Would be a fun project .

Yes the 30 is for sale again at a price that leads one to believe Tower thinks it's an OS.

Re: The Saito twin that never was

Is Horizon seriously bringing the .30 back on the market?

Wow! I need to check that out!

Yes I was referring to a twin made with the Saito hemi designed cylinder. The problem for the amateur machinist is there are no left cylinders and making one would not be that easy.

Yes I have a Saito 60 twin and have run it quite a bit. Not exactly outstanding for HP like the hemi Saitos are but it is very smooth and will power a scale model designed for a 40 to 45 2 stroke. A 56 single beats it hands down though.

Re: The Saito twin that never was

I had a SAITO .60 twin. It produced one power stroke each revolution. It turned a 12X6 prop a little over 9,000 RPM. It flew my 1910 Monoplane with a 80" W/S vey well. I had to dive it to do inside loops and cuban eights. I did an outside loop from level flight.

Re: The Saito twin that never was

The 60 twin the OP speaks of was sort of a model Continental and was the predecessor to the 90 TS. Used 90 TS's are quite pricey if you can find one. The 60 and the 90 TS were even firing smooth runners.

A 60 made with two 30 cylinders would be a real jewel whether odd or even firing.
