Very interesting. I have topped up my avgas tank with v power 98 before and did notice it go a bit better up high in the revs. I thought i was imagining it but reading that it seems i was not.:) Good work as usual cactus.
Yes the coil will work. I would check the earth at the kill switch. Could be the problem. The cdi off your 125 wont work either, the 150 has an inner rotor yx or outer rotor if it is a lifan. If you get too stuck take it to a mechanic and get their oppinion. A six pack will usually be a good...
I have advanced mine and with the pumper 27mm carby i run it starts really well and the extra advance is noticable too, power wise. I also run RF100 avgas in it which probably helps too. I think the initial squirt of fuel from the accelerator pump may be the reason for it not kicking back as it...

Spray and wipe with a scrubbing brush before you wash them. Then armoral them after they are dry. For the really bad scratches on the hard bits i use thinners on a rag. Just dont rub too hard with it though.:) My tech 2s still look like new after a year of thrashing.
