There you go, twice as flat.

Ron Cubel built a Margay New Breed with twin flattop 101's running a gearbox. Going to have to look for a photo.

I had dual Mc30's with GEM dual bottom carbs on my '62 Go Kart 1200. There's not a photo anywhere of that kart. It was a pretty beast. Ted

I decided I needed a flattop 820. It fits better on a 61 Fox when I turned it upside down. This one is modified and I also put a stock one together. Should be fun if I get a chance to run it this summer/fall.

Chris is right, I got the idea after We fixed his MC1 last winter and seeing Bob's flattop. We now have something that Chris can run at Fremont with Bob.

I can speak for 'Bob' when I say " I know what you two are up to, that's probably another one of those 12 inch motors " :o :o

It's just a stock bore and stroke 820, had to keep it fair. It only has a single carb so it'll be low on the power curve average but great torque.
