Supposedly the 362, even though it's a strato, likes numbers similar to the 361. I haven't degreed a 362, so I can't say much for it myself.

 

Is there a baffle or sumfin in that 150? An MM on a 200 itself gives nearly 25%.

The muffler drilling, from what I can see, allows the exhaust a direct path out of the can, same as the MS200T, I think the initial 5mm hole probably gave a 15% increase so my mod afterwards of 7% would have been around 22 - 25% overall.

 

Degrees - 5% and not really happy to take it much further!

 

I could make the outlet 10mm but TBH, I the gains to be had are pretty much done and don't want to charge the owner a big lump of dosh for a few percent - makes sense IMO.

 

The MS362 is a different case - loads on the exhaust, almost nothing on the inlet apart from a big old bevel on the casting that can be significantly reduced.

 

The back end of the piston with the Strato cut outs, reduces the chance of widening it by much more!

 

Should go a fair bit better once done!

If its loads, you'll prolly have to bring up the transfers to ridiculous blowdown for real rpms in the cut. I read somewhere that Brad used 16* on some of the bigger stihls. Yes, 16*. That's with an equally angry 164* or so on the intake. I really go easy on the blowdown since I prefer most work saws to have good torque at usable RPM's for felling. On a 50cc saw, I may go a bit more on blowdown.
