You might need a pump.

Ok, a friend has an fg33-3. When tuning the more I richened the top end the more rpm it got. I backed the needle almost all the way out- several turns, like 12. The engine was not getting enough fuel. It still leaned out in the air, overheated, and died. I have seen this issue with several radials, inuding Moki and Evolution. Oh, and do not expect it to ba anywhere near as powerful as a 2 stroke single 60cc. It will feel like you're flying with a 3lb lead brick on the nose with the power of a modern 35cc single.

Wanna buy a fg33? He's got a fire sale on his $1200 paperweight.

Oh, I'm saving up for the 260cc evolution, and a $400 vogelslang aero fuel pump.... it ought to put out about the same power as a 120cc 2 stroke.

I think he just sold it on Ebay for $740, only had 3 bids. I guess Saito doesn't hold their value like they use to.

FG-84 mod should work for the 60 and 33.

I was not at home when the USPS tried to drop it off on Saturday. Shipping including in/out of custom took 3-4 days from Japan. I'll go pick it up tomorrow at 6:30AM. The shipped price to my door in Friendswood, TX was around $1,250. It depends on the daily exchange rate. I thought it was a fair price.

I weighed the pieces on my digital scale which has 1/4 oz resolution:

1. Muffler flex lines & bracket: 3 3/4 oz
2. Ignition: 7 1/4 oz
3. Engine w/plugs: 3 lbs 15 oz
4. Standoffs + bolts + spinner nut: 5.5 oz

Some stats as compared to the twin FG-57T and the 3-cyl FG-84R3. Note that these are published stats:
1. FG-60R3: 1850g, 4.5HP (or 2.43HP/Kg)
2. FG-57T: 2180g, 4.5HP (or 2.06HP/Kg)
3. FG-84R3: 3056g, 5.7HP (or 1.87HP/Kg)

Engine quality is very high. The looks and feel are impressive. The post machined (?) crank housing is not nearly as nice as that on my OS 40cc 4 stroke. There is no English instruction other than the short paragraph on how to install and dress the muffling flex. The carb does not appear to have a choke. I'll see about mounting it on a test stand this weekend. Got to cut the grass first.

I wonder how this engine would do in a Ziroli 118" B 25? Of course, two of them!

I must say that the cylinder casting is immaculate. The engine is very light for a tri cylinder weighing in about 1 lb AUW more than a single 2 stroke 60cc. I have a EME 60 and a GP 61. It is designed to swing the same 23x8 to 23x10 prop as a single 50/55cc 2 stroke. I believe it will do very nicely in a warbird like a Zero where nose weight is desirable. Don't know about a twin because I have not put my Tigercat together yet. But when I do it will have two 30cc.
