Could someone give me yay or nay...

I'm still new to the rotary stuff, so I wasn't quite understanding the whole "long block" vs "short block" other that the basic understanding. I also didn't understand the difference between a 13b and a 20b, but I think i've got it so could someone say "Yes, you go tit" or "no you don't."

Ok so 13b is a 2 rotor engine and a 20b is a 3 rotor engine which is similar to the 13b and the size and aspects are teh same except for the 13b? I think I have the first part right, not the second. Now as far as the rotors on the 20b go obviously they must not spin all at the same time as far as balance so the output shaft must have them spinning insuccession, like due to them being sort of a triangular shape one is always at top, another in each corner for the balance of the engine? So in that fashion it would always be doing intake,compression,combustion,exhaust? Or do I have that right? I've been looking around all over trying to get this stuff and put it in my head, I'm used to my kawi or 2.3 on my car Hope I'm getting some of this right.

Now one question i wasn't able to find, can you stick a weber carb on a 13b?

 

Yup, a 20B is basically a 13B with an extra rotor.

As for the webber:

Numbers look nice on the weber

 

Yup, it's a good way to go if you like carbs...

I like EFI myself....
