RE: Help Identifying Engine
It's a NORVEL C/L Revlite -- you would have to count the intake ports to determine if it is a BigMig or AME. These engines shipped with the tank attached -- some had the springloaded vent and some did not. They also had two different pickup tubes that could be installed -- one went to the center of the tank on the right side (C/L) and one turned down to the bottom center of the tank for R/C and freeflight usage. Probably the tank has a small dimple on the backplace for the pickup tube. The backplate was glued to the rest of the tank and occasionally the glue would break off where it was squeezed out of the joint. It looked like a blade of grass inside the tank.
Your looks to be the next to last version that NORVEL manufactured -- the thrust washer is turned. The last engines that shipped had a cast thrust washer.
NORVEL had 3 different venturis for the controlline model -- a small diameter throat called the EZ Start, a larger mid-range for the B6 (BigMig .061) and a high performance venturi for the A6. The high performance generally required bladder pressure because of the large diameter and low fuel draw.
The plug is the standard Freedom XL plug that came with all later model NORVELs.
