wood burner I would think is a good idea , I should of thought of that , I put mine outside in an old wash tub with like half gallon of alky and lit it , took five/ ten minutes worked good ,
Thanks for the input ! I'm going to put it in the wood burner and keep flipping it around on top of some logs so it don't get to hot . This pipe is funky !! I don't think any one ever cleaned it out I never did and I ran it for two years .
Since you're not in California, should be fairly easy to find an auto parts store that has one. Way simpler than trying to burn it out, and gets it *way* cleaner inside.
On my old scooters and dirt bike I would use a torch and get it burning inside....then turn off the flame and just feed it O2, follow the heat/flame inside and adjust how much to feed it till its out the other end.
Hot Tank? I don't think you need to from California to find they have vanished. I don't think any have been around here for at least 20 years (Massachusetts). Some furniture restores have them but I doubt they would want to soak a 2 stroke pipe.
