I have a 32cc rcgf engine that I would like to get smoke system hooked up to. I think I understand the basics, you pump smoke oil to the muffler, but I don't have a muffler with a hole to pump the fuel to. I saw someone who had just drilled a hole there and used, what I would assume, is heat resistant silicone to hold the fuel line in place. I am wondering if this is a good idea. I essentially am just wondering the tips and tricks of installing smoke systems that I should be aware of. Do they need vent lines? Do they use the same fuel line as gasoline?
