No but you will have stuff hanginging out everywhere. If you insist on a g-62 I would go with a RALPH CUNNINGHAM lightened hub and built in CD ignition I would also check out TONI CLARK carberator 90 degree carb manifold page 184 With these two mods you will have one slim and trim great running powerful easy starting G-62

(500mah or more) Making a great engine better
A standard
RCA Audio Cable is used to connect the ignition to your battery. Any NiCad of 500mah and up will run the engine for approximately 2 hours. The ignition will accept a
4.8v or 6v battery source with no regulator required. This engine is available in 2 different configurations, one with the
automatic electronic timing advance (as shown), or with a
standard mechanical timing advance mechanism.
A
custom carb block replaces the stock one to
rotate the carb for easier throttle linkage in aircraft applications. Therefore, the
throttle linkage is already set up for a straight shot back to the firewall and includes a ball-link linkage pre-installed, ready to go. Another advantage of this custom carb block is that it is only
3/8" thick, about half of the thickness of a stock block, allowing you to squeeze into tighter cowl restraints.
The choke lever is stock and provides for a straight shot out the side of the cowl, unless you decide to modify with your own preferred bellcrank and linkage to change the line of pull. The
custom prop shaft/hub can be made to whatever length you require. The average shaft provides a distance of 6-5/8" from firewall to spinner backplate.
Initial observations of this engine is that it appears to be of very high quality as it starts with the bullet-proof reputation of the Zenoah engine line, and is further enhanced with some high-quality engineering and features from
RC Ignitions.
At approximately
6 ounces lighter than the stock Zenoah G62 (Magneto), the engine already provides more power to weight ratio than its stock counterpart. Add to that the easier starts and smoother idling traits of an electronic ignition and you have a great combination. Many satisfied customers have made claims that the engine simply runs smoother, stronger and faster than any G62 on the market today.
Here's another big plus with this conversion engine... warranty. There is a
lifetime guarantee on all ignition parts and mount, including crash damage! While it does not cover the Zenoah components, RC Ignitions will straighten cranks for
$40 plus shippping.
So far I am extremely pleased with what I see and can’t wait to get this engine installed and give it a try. If all goes well, I expect that this could prove to be the “no-brainer” standard for warbird and scale airplanes in the G62 class. And, with the strong power, smooth running and 6oz lighter weight than the stock G62, it is a very serious contender for those flying Sport and 3D planes in the 50-60cc class.
