Hello Allan. The CMB 45 HR and the MAC 45 carbs are the same. They will be ready in the near future.

The 2008 CMB 21 Valvola carb with the 2 mounting bolts will be avaliable later.

No price has been set at this time.

Thanks, Charles

Hello Terry. I will have a small batch of Zoom 21 carbs ready in less than 2 weeks. Like the Zoom 67 carbs, I will try to ship these in the order that the request were received. You were already on that list. Thanks for being patient.

Hello Charles, if you have any Zoom .21 carbs that are not spoken for, please let me know. I sure could use one more. Thanks, Richard

Hello Richard. Gotcha on the list. :)

Some questions about the 45 Zoom carb :

Do you have a picture ?

What is the dia of the bore ?

" The CMB 45 HR and the MAC 45 carbs are the same ". The CC of the mounting bolts are not the same, so have you made the holes elongated ?

Will you make a version for the CMB 45 RS ? If the body of the carb have enough material to make a 2 mm deep hole, it will be easyily modified with a 14 mm endmill.

Wow too funny, just sent a p/m to Charles asking the same thing. Personally I think the 45RS motors outnumber the 45HR's out there by a good bit so hopefully we'll see a Zoom for that application soon. :)
 
Hello Kim and Don, the bore on the Zoom 45 carbs is .437.

The difference between the carb mounting for the CMB 45 HR and the MAC 45. is only very slight. No problem. As for the CMB 45 RS, I do not have one of these engines yet to make a carb for it. That project will probably have to wait for the next cool season. It is almost testing (play) time of the year now. :)

Thanks, Charles

Thanks for the info Charles.

I am a bit surpriced with this large bore. If the spraybar also is short with a small dia, low end and axeleration will normally suffer. The large effective area gives low air velocity and "poor" performance exept at full throtle.

Have you tested many different bores ?

Is the secret with this carb performance the shape and form of the spraybar ?

Also sent you a email.

Hello Kim, your answer is yes, no and maybe, in any order. Any more information is classified. Have to get security clearance from the CIA, KGB, FBI and possibily the Department of Homeland Security. :D

What is not a secret is that they work VERY WELL. :)

Thanks for the interest, Charles

Kim if you had one of these babes you would understand how it works. My buddy just left with my 67 Zoom as i could not pry it back from him... Ps yes Mark it was Tom D and you know how picky he is.........
 
Hello John. Now that the Picco 45 Black Heads are back on the market, I believe that they will be inline for a better carb. Just not enough time right now.

Thanks, Charles

PS: One more good reason is, that is the engine that I am running in MY rigger. :)

Nothing like a personal incentive to get that project going. Definitely would be interested in trying one of them.
 
Charles

Have you put me down on your list for two ZOOM 45 carbs for CMB 45 HR engines ?

Have you got my email, and is PayPal OK ?
