Thanks for the quick reply and the drawings. Made it easy to understand. Had a couple of more questions. Looking at the 3 line setup it looks like as the tank fills and the fuel level rises, will the fuel get to the carb and maybe flood the engine? Also, I'm going to use a 4 stroke and will try to turn the header in so that the muffler will be hidden in the cowl. I'll have to open the bottom and maybe put on an extension to the muffler. I guess with a setup like that the only way I will know that the tank is full is when the fuel drips from the muffler. is that correct or is there another way? Lastly, I found one web site, Central Hobbies, to look at fuel dots. Do you know of any other web sites that I can look around for the fuel dots? Any brand you have had luck with? Thanks again, Mike, for all your help....
