so I got the sprocket on the back wheel
I used some bits of 1/8 inch plate which I threaded to put on the inboard side of the spokes
this is a 32 spoke wheel so I drilled a 4 bolt pattern & used 8mm bolts
the sprocket centered perfectly I put tire rubber on the inboard side & inertube between the the sprocket & spokes
I took apart a dirailure ? I actually used a porting burr on the inside of the plastic sprocket so I could get a skateboard bearing in there
it keeps the chain pretty tight but this engine is bump started so Ill need something more robust with a skateboard wheel as a tensioner
when the chain is pulled tight it dosent hit the frame on top by about 1/4 inch
this is about where it stands for now
take care
