If you get a new Tuxing Twin be aware the electrical plugs need work they are very loose. Make sure each wire plug is crimped tightly as when they come from the factory they may need to crimped a little tighter. A loose fit will arc , and burn. My model the TXED012 Had very loose wires. Just use pliers to crimp , and tighten up the wire connections. Use Seco lube 500 oil , and use distilled water with antifreeze , and something like Royal Purple Purple Ice , or Water wetter for the cooling system. Some guys on the Nation used a dual water pump set up one for each cylinder. I'm using a Walmart 40 gal tote with a 20 gal water supply , but I live in Tucson Arizona one of the hottest places on Earth lol. Even when filling my 6.8L it only reaches 120°F. The cooler these machines the better. OldVet
