I somehow doubt that a mini-bike type engine is going to have the
compression that this mod calls for. Stranger things have been done
though...

Nah! Tends to blow the spark out..............
Actually, it looks interesting. If you try it, let us know
what works & what don't.

well....the page 'did' mention side valves...well, that ol' Tecumseh
motor aint nothin' but a sidevalve/flathead design.
If I read things right, the groove(s) makes the fuel/air mix swirl
around better and kinda aim the flow at the sparky plug. As for the
compression, I think I gotta flat piece o' glass here somewhere, that
and some sandpaper will increase my compression a little bit....no it
aint precision milling, but it aint really a precision motor now is it?
<G> (just have to make sure the valves don't hit the head when I'm
done)...ohh, valves...I better check those while I'm in there....

I don't have anything to try it on at the moment - or do I?!?! I bought a
set of used heads from Topp on the EKII auction a while back...HMMMM. This
might be some good fun.
Only issue I see is that I was planning to R&R them and do a mild port job
(mostly just cleaning the castings) before install. If I baseline them with
stock vs. this mod, *and* the mild port, I blow the experiment. Sounds like
a likely project for next winter now anyways though. This one is going to
be over soon <the sound of a fist violently thumping a wooden object>.

If'n you get that head flat enough, they will run with no gasket and just a
little gasket goo such as high temp silicone. You don't need to worry about
valve to head clearance either, there is a bunch of it, that is unless you
start milling of a bunch of the head!
I have a 5 HP B&S out in the garage that I had on a go-cart a few years
back. I milled a bunch off the head, something like .100", ran a stock
gasket, a Tillotson carb, a 3 HP B&S flywheel with no key so I could advance
the timing about 1/2 the keyway. Made an adapter to lower the coil down to
the smaller flywheel. Damn near needed two hands to pull start it but that
little sucker would haul ass! 0-40 MPH in 50 feet or so. All stock
internals, but I polished the rod thinking it would help hold it together
better. Never did blow it up!
