Slant won't start!!?!!?!?

I haven't had as much time to work on the scamp as I'd like but I did another compression test and got the following.
Cyl
1-45psi
2-30psi
3-90psi
4-85psi
5-85psi
6-30psi

I also bought an in-line spark checker and the little bulb lights up pretty good on all wires. Tried to set it at 10BTDC, 5BTDC and 0TDC but still no start. It did change in sound though and sounds like it fires in one cylinder but barely. Oh, also tried starting fluid.
