Novice Question: C77 engine v.s. CL77 engine

Hello,
I was hoping that someone could help me understand the overall differences between C77 engine and CL/CB77 engine. First, off I understand that C/CA77 engines were single carb engines, while the CL/CB77 engine were dual carbed. Is there a noticable performance, ease tunning, starting difference between the two. If there is, was minor. Which engine is easier to get parts for today? Is a C77 engine any more collectible than say a 66 CL77 engine? I know these are kind of off the wall, particular question, but I would love to hear anyones insight or opinion on the matter. Thanks Adam

CA77 have a 360 degree crank-The CL and CB have a 180 crank.

Forgive my ignorance, but what exactly does that mean? I'm familar with oddfire, 90, and 180* cranks in the context of car engines, but not the difference between a 180 and 360 in a Honda twin.

360 crank both pistons up at the same time,180 one up one down

I thought it was something like that. Thanks.

Something that I learned here was, the CL crankshaft doesn't have an oil passage to keep the starter sprocket (on the crankshaft) oiled, like the C, CA and CB do. So, if an electric starter setup was installed, there would be no oil to the sprocket on the crankshaft. I think I worded that right. Anyway, you can't put an electric starter on the CL motor without changing the crankshaft. The CL has a bit more power than a C or a CA motor and I think parts are about as plentiful for one as they are for the other.

Someone with a bit more savvy on this subject can probably answer your questions better. What do you have in mind?

Later on, Bill

Where does the the CL get more power than the CB?
They are the same engine but one has a tach drive and electric starter. ...........lm
