Combat and AV8TOR. You guys are the shizzo.

My engine came from a Ryobi 720r, 31cc marked on the label. It has single, wide transfer ports, with no slits. The exhaust port has a center divider. Single ring piston, ZAMA P11 54P carb, 7.5mm venturi. Looking at the exhaust port from the back of the engine, there are two casting lugs, one on either side of the muffler mounting bosses. There is a "5" cast onto the left one, and a "95" cast onto the right. There is also a letter "D" cast onto the jug, just above the left jug mounting flange. My crankcase has the separate, bolt-on mag shield. Just to the left of the bottom lug, a "24" can be found, with a cast-in circle with the number "5" in the center with some other hash marks. To the right of the same lug is a cast-in horseshoe shape with the letters "ST" in the center. These are the only distinguishing features I can find on it, and the serial number has been lost long ago, sorry.

Do you guys have any part or model numbers for the larger carb? I'm going shopping on Ebay tonight.

Bought my magnet(s) last night. Radio Shack had exactly what I was looking for. 3/16" x 1/8", 2 in a package for $2.99, no shipping!

Combat, I have some very thin stainless steel. I have .008", and a smaller amount of .012". I can send you some if you like.
