    You guys shipped the engine with the wrong carburator. I used the carburator that I had on hand and reworked the crank case pressure tap. Motor runs great now.

    Almost lost my arm trying to start this engine. The carburetor settings were incorrect. Had to reset them per the manual. Did not expect such a hassle. Hopefully, that’s my first and last issue.

Q & A

are the muffler for the 40cc twin fits the RCFG 50cc twin? Rene Alvarez asked on April 17, 2022

Hi Rene,
The 40 Twin Stinger mufflers will not fit the old v2 50cc Twin.
While the exhaust port is the same size, the 40 Twin Stinger uses a 4mm bolt, the v2 50 Twin uses a 5mm bolt.
