I think I'll try it first without the in-muffler pre-heat or I'll pre-heat wraping some copper tube around the cylinder head and tap as you said, next to the engine's exhaust port onto the flat part of the header.

If that doesn't work, I'll try in-muffler pre-heat.

If that doesn't work I'll get a 30% Extra and a big gas engine.

If that doesn't work, I'll shoot myself
