Was just looking though a few of the 170 plus pages on the gas powered Tadpole. I wanted to know if two or four stroke engine is used. I thought there was a faux part attached to the head. Some oiler that is not needed, but looks the part from the gone past. I know two stroke have exhaust not up by the head but middile of the cylinder along with the other port if not through the case like on model glow plug engines. I was looking at a few I have today while looking for a 250 watt American Flyer toy train transformer. Is there Marvel Mystery Oil that works like Barrs Leak? Two stroke use oil that keeps getting replaced unlike Four stroke, that maybe the same as my valve cover gasket self fixed the leak? Other is I am going looking for some nicrome wire of the right diameter to buy to use with the transformer. I want to cut a nice radius curve with hot wire on some high density foam that I bought to make seat cushions for my inflatable pontoon boat. My spine will cause pain since my disc went bad in my neck. My pain of the ulner nerve affected might only be suppressed to an extent with medicine. The seat on the pontoon is pumped to 2.5 lbs and really is not soft. I intend on making a jig to use in conjunction with the hot wire tool I'll also construct. Some time to have the boat out again. Windsurfing I had not modified anything to continue since the ailment, but I see a need for better access to launch or some thing to wheel down narrow path my gear. Your looking for metal? Not available? I know I've see estimated to be about 75 Tons of anchor chain down by Davy Jones. My lift bag would not even get one link to the surface while on Scuba. Large as soda can size diameter and two feet long each link. My boat I think I remember says 1200 lbs on the transom. The movie the Deep came to mind, but this probably does not warrant the same.
