Superfast,
I bet what you have is a A&M 2.0 built by Gary after her bought the assets of A&M Aircraft from the bank. There were allot of existing stocks of engines and engine parts that only needed a technician to assemble them. Gary retained two such people from the old company and together they painstakeingly hand assembled and ran engines. The 2.0 is one of the best engines of its class ever produced by anybody. And the claim to say that is simple it ran and ran and ran.....was not the most powerful or the prettiest but it was like an old castiron straight six auto engine there wasnt anything you could do to other than crash it to make it not run. Some people might poo poo that but these engines that came into the shop where the owners claimed were garbage only needed papa Gary to apply some TLC and they sat up and barked like a big dog.

The 2.0 was the origianal idea of Al Willart of Al and Marylin Aircraft ( ie...A&M Aircraft) Al's original idea was to make all the engines like the 2.0. from the smallest to the biggest and the twins ect... but fate was not to be with them and the rest is history.

Sitting here reading the original literature from AM/Brison it says the 2.0 = 32.7cc wgt 2.75 lbs thrust 16lbs props 18x8, 18x6-10, 18x10. Al and Gary both run down to the hobby shop and buy what ever is on hand (usually zinger or TF) and use that just like you or I would if we had the motor. All the 2.0's should turn 7100 -7200 RPM on an 18x8 or 18x6-10 Zinger prop.

The ignition I would not use. Call Bill Carpenter up and buy a CH ignition for a TCSA AM 2.0 Make sure you say AM 2.0 cause it makes a difference.

Never worry about parts as long as Brison has 2.4 you will always have cases. The 2.0 and 2.4 share almost all the same parts.

Well you got a keeper.
