This tells you the exhaust manifold gasket is leaking. Remove the exhaust pipe/muffler and clean the gasket surfaces well. Check that the surfaces are flat by sanding lightly with a block of wood or metal wrapped with sandpaper. Gasket material is available from auto parts stores in sheets. You can make your own gasket. I've found that a gasket about 1/8th" thick works well. I'm not a fan of studs and nuts so I replace them with Allen head cap screws. If you have a 2 stroke engine the bolts will be 6mmX1 thread and about 20mm long if you use the thicker gasket. Good luck. Let us know how you make out.
