Need help identifying engines

Re: Need help identifying engines
OK here goes: #1 Jim Walker 'Firecracker' .065*
#2 Royal Spitfire -also .065
#3 Norvel AME/Big Mig 049 or 061 (should have '0.8' or '1.0' written on the side in black ink to distinguish which size version)**
#4 G-Mark .061
#5 G-Mark 'humming Bird .03
#6 K&B Aurora Fury 049
#7 Gilbert .07
#8 Ohlson&Rice 'Midjet' 049
* essentially a badge engineered derivative of #2
** you can distinguish between the AME and Big Mig variants by removing the head and looking at the transfer ports-the AME use three large transfers, the Big Mig uses three sets of paired holes of smaller overall area.

1. Jim Walker Firecracker, it came with a hand held bulb and a long thin tube which connected to that throttle flapper for throttle control.
Engine to the right of it assuming it's #3
Early Norvel, if it's marked 1.0 in ink it's a .061. if .08 it's a .049. It could be a Big Mig which has 5 internal cutouts on the cylinder liner ( Visible with plug removed) or 3 ports indicating a AME which is a higher performance, somewhat like Medallion vs TD. Big Mig and AME versions were available in both displacements.
2. Royal Anderson Spitfire .065 displacement
4. I believe it's a G-mark .061. .061 is casted onto the bypass on the opposing side that you show.
5 G-Mark .030 Engine with no number to the right is a Gilbert .07
6 K&B Allyn Sky Fury Engine with no number to the right is a O&R mite .049

Re: Need help identifying engines
That's funny, when I first posted my take on the engines, I didn't even see Chris's post. Pretty darn funny actually

Re: Need help identifying engines
Thanks everyone and that was helpful
The Norvel is an AME .061
For the Fury, is it "Allyn" or "Aurora"?
For the O & R, is it "Midjet" or "Mite"?

Re: Need help identifying engines
The Fury was originally produced by Allyn Sales Co-BEFORE they merged with K&B-and available in various models-inboard, outboard and aero. AFAIK only the 049 was produced-the larger twins only came after the merger with K&B...so your engine could be referred to as an Allyn Sky Fury 049....or equally validly as a K&B-Allyn Fury....depending on how long production continued after the merger-but definitely NOT as an Aurora anything...
Ref: AMEE pp4-5
I stand by my original identification of the O&R as a 'Midjet' not a 'Mite'-the former has the large tank, the latter is tankless and with a shorter crankshaft bearing...

Sorry, I got em mixed up. O&R had eagle and O K used the bear. Early Midjet has brass eagle on the cylinder, I was thinking bear.
