Default Older CMB hydro .67 Purple head

Help! Have an older CMB .67, using 30% nitro,good conpression. Are MAC .67 parts interchangeable with CMB, or where can I find CMB parts? Is the Green head CMB 67 the same as the purple head?

They may but I'm not 100% sure. Your best bet is to call CMD Racing. The number is on their site www.cmdracing.com . You'll probably get Rene or Donna on the phone. Don't worry, these ladies know their stuff.

CMB's can be tricky as some are model specific. Some are made for hydro's while other are made for mono's. What he differences are, I haven't got a clue but it must be in the timing numbers.
there are parts and dealers around but finding them is the hard part. Mark Sholund at Props4you is one that I know of and Mike Hallam in Canada.
