Zenoah G4K 42cc RC gasoline Model Airplane Engine with Walbro Carb: HDA 246 710

Description

Zenoah 42cc G4K RC gasoline Engine
... turns 18×6 prop at 6,900 rpm!
This is a G4K "utility" engine manufactured by Husqvarna Zenoah Co.,Ltd. as used in pumps and weed-whackers, and such. A handful of years ago it was modified into a powerful RC model airplane engine!
I could not FIND a picture of this engine online, so I contacted Husqvarna and asked about the serial number on my engine and I got a reply! ...
Thank you for your inquiry.
It seems that your engine is definitely G4K.
The displacement is 41.5cc.
Thank you ,

So... built as a workhorse for
Husqvarna/Zenoah products... it DOES have the Zenoah logo on it.
(Included in your package is something I found online while doing my research: an 8-page instruction manual for some kind of a pump assembly that features a G4K engine... it has tips for adjusting the engine.)
This Zenoah engine has a Walbro carb and a built-in electronic ignition... no magneto, so you have to plug your 4-cell (5V) NiMh or NiCd battery into that Futaba-style plug that you see bundled-up in the photos.
That Walbro carb has numbers on it:
HDA 246 710
the other side of the carb says Walbro and the number 21-245-5-2
See the photos... THAT is the engine you are buying. The previous owner says it runs strong and
turns an 18×6 prop at 6,900 rpm!
The motor weighs-in at 4-pounds, 7-ounces.
I have it carton-packed and ready to ship from Kingman, AZ ... good luck on your bidding!
Condition is "Used". Shipped with USPS Priority Mail.
