This is where a tuned pipe pushes that mixture back into the cylinder by way of sonic waves. However, because that precompression forces the mixture into the combustion chamber, a bit also gets pushed out of the exhaust port. The power stroke then precompresses the mixture again, and the cycle repeats. The compression stroke then causes low pressure in the crank case, drawing fuel and air into the case. That will work for smaller jets.Ĭlick to expand.I know the engine is an electric/pull start 70cc two stroke engine, and it works by precompressing the fuel/air mixture to force it into the combustion chamber. Or get a wax carving set and use the needle point tools and compressed air. Hey, fun fact about those jets: You can clear them with a mechanical pencil. 66 though, but I found out after the fact that those engines come stock with a. Oh, and I think the reason my spark plug blew is because I went way too small with my jet. I actually took apart my carb a couple times, and air blasted everything. What's making it not start anyways? Most of my no start issues with my 66cc were simply because of gaskets, carb, and slight electrical. ![]() If I could make it last more than another 20 starts, I will give it back to you saying "It's fixed." Hey KC, any chance I could get that broken down engine to tinker with? I've always wanted to work on an electric start two stroke. All the bright headlights I found have not been lower than 20W, other than cheap, weak, throwaway lights. Particularly the watts, because that is the biggest deciding factor as to what you put on the system. Those magnetos are probably only 10A 40W generators, so you can't put a whole lot on them. That's 56A allowing me to place a bit more on the bike. ![]() The amplifier for the audio system is likely a 10A amp. That right there is 115W out of possibly 200W put out by the alternator. My audio system is a 60W system, my headlight is 35, my tail light is about 20. Voltage is simply the rate of flow, amperage is the strength of that flow, wattage is how much work that flow can make. ![]() Everything you have on that system must NOT exceed the wattage of the system, nor the amperage. Click to expand.It's not just the voltage.
