Barries Aspen stickers are going well:thumbup:

The point of a lower ratio is that when the oil precipitates, it creates more of a seal around the piston and ring(s), which increases the overall compression, as the oil seals the cylinder as the port closes, so less mixture can escape, whilst it may not be much in terms of port timing, it CAN make a huge difference in psi, it doesn't always!

But it should do that completely adequately at 50:1, but without leaving unused residues.

Stock saws yes, but ported saws have different timings so the residual oil will help seal the cylinder quicker, especially on a higher rpm saw where the exhaust port has been raised to give a substantially higher rpm range

Fair enough, ported saws are beyond my experience, so I bow out, gracefully I hope.

No, your points are very relevant, I use aspen in my ported saws, but I find aspen precipitates it's oil perfectly and leaves a residual oil lining anyway. But those hunting for the slightly higher compression values do use a lower ratio, such as wyk and his 361 of doom having given my 090 high compression, I tend to shy away from that!

I'm ok at the moment, thanks

I am sure Wes will be about soon to give an opinion but thought he rubs a mix similar to mine:confused1:

I thought he ran between 33:1 and 40:1?

Kawasaki engined strimmer.Impossible to start.Didn't take long to spot the fuel mixture bubbling through the cylinder gasket. Dirko'd up running lovely.

Could anyone tell me the torx size that fits the cover to the chain brake mech on a 201 and the like? It's smaller than the standard t27.
