Hey I have a question though I am not new to RC Engines at all. I am just curious to what happens to a Nitro engine say the Super Tiger .40 Ringed when you dont use a Muffler at all. I have never run a Nitro Engine with out a Muffler before so I have no idea, But I do have a few assumptions. 1 Noise 2 Loss of pressure in the fuel tank. Though a Fuel pump can take care of that and I could Bear the noise or at least Dampen it some how. Again Does the piston burn up or Does nothing at all happen? Thanks Anthony.
1. It is too noisy.
2. There is no pressure to the tank which leads to inconsistant fuel flow.
3. Without the backpressure from the muffler you will not get a good idle as the plug will want to cool down. Before mufflers they used to put rotating baffles or covers that moved in or over the exhaust port. My first K&B 40 had such a baffle linked to the throttle.
