There is a good bit of work to be done.
What led me to this point is that the petcock went bad and it dumped a full tank of fuel into the #2 carb and filled the crank case with gas. I expect the cylinder to be glazed. It was holding no pressure, I soaked it with Marvel Mystery oil and gained a small amount of pressure on that cylinder (cant remember the numbers now, its been over a year). I have found a replacement engine and will start to replace it soon. I will be working on a carb job, valve job, replacing gaskets, cleaning as I go.
I will also need to find several parts, the first of which is a complete exhaust. I can find all kinds of aftermarket 4 into 1 and 2 into 1 systems, but I am coming up short trying to find something close to stock that isn't 30+ years old and at the end of its life. Do you all have any suggestions on an exhaust that I can get that is close to stock as possible (or better).
