Hi!
OK! Here we go!
No modern ABC, ABN or AAC engine needs preheating with a heatgun to start. This could perhaps be used with old K&B ABC pylonracing engines in the distant past

but not today with our modern ABN set-ups!
Most modern glow engines (two stroke)are ABN and are set up so loose that they are easily flip started with a finger! And more easily soo with an electric starter!
Use either a 12V 10A Motorcycle battery or a 14,4V , 2000mAh LiPo cell to power your electric starter.
7A Motorcycle battery works too, but it cannot deliver enough amps when it comes to starting big 20cc -25cc four strokes in the long run.
When it comes to all the Chinese two stroke engines, like the ASP, Magnum, SK, Kyosho GX and SC with a two part silencers, they are notoriously bad! As the silencer screw will always loosen when the engine gets hot.
The only solution to this problem is screwing the the two silencer parts together with small metal screws and using silicon as gasket.
