Many thanks for your ideas, Im now out of the break in cycle and ran my first tank of gas thru it. I ran 93 octane mixed at 28:1 Noticed no difference/to very little difference. I have a speedometer, and made sure the head bolts were on snug before i opened her up to see what she would do. It tops out at 21 mph. Im only 150lbs, so she still should do better. She still is a dog and eats gas. It is very sluggish between 0 and 15mph, after she hits 15 mph and is there for a while and accelerate, she moves, and sounds the best between acceleration, from 15mph to 18 mph. Coaster brake is not on/locked. My next step is im going to try and put the muffler i got from BGF from the engine i blew on it, and was thinking about putting the slant engine head on as well from the blown engine. In doing this would i need to do any thing else besides get a new head gasket and put on slant head? May try tinkering with the carb float forks as well if muffler doesn't work.
Hoping i might somehow return the favor of the many ideas you have given, hopefully this will help someone that ran into a problem i had, and had to innovate something that worked. It is in regards to the mounting of the gas tank, my bike had a wide/fat top tube and the mounting screws they give me were not long enough to clear and install the mounting brackets, and you can't take out posts and install longer ones like the engine. So i bought some black plastic wire holders from the hardware store and mounted two of them on each tank mounting post. I then ran two long zippie ties at each mount under the top tube of the bicycle. This also allowed a spot for the clutch cable and ignition kill switch wire to run thru. I also added some double sided sticky tape to the bottom of the tank where it fits on the top tube, and it provides a strong secure tank hold without having to drill or monkey around with brackets that will scratch your frame.

Also check out the post im about to make on a "Quick Release Cargo Trailer" in traveling and commuting. i just got done building it. I built it out of 1/2 inch EMT conduit i got from the Hardware store. It is a strong trailer and also a breeze to disconnet from the bike.
Here are some picts, more in traveling and commuting thread.
