I ran through our neighbors garden when I was 4 years old and squished all kinds of rhubarb...

It looks nice and even to me as well. Jer has that "machinist's eye" though.

Look where the left front transfer flow hits the popup edge, and instead of flowing twords the center, it diverts and flows back twords the intake. It does it on the right side as well, but u can't see it because of the glare in the pic. Normally flow twords the intake is a good thing, but look at the thickness of carbon where the back transfers flow. There was still quite a bit of fuel there during the ignition process, not in the chamber where it should be.
Then again, I could be crazy....

question to the builders ,is there a general rule of thumb for port shapes or timing if want tourque power for cutting bigger timber ,or a higher rpm screamer for making a fast hot rod for smaller stuff ?

I build most of my engines with conservative exhaust numbers and a lot of compression. I like lots of torque in any engine......you can gear for more chain speed if the engine has the power to pull the gear.
RPMs don't do any good if it can't hold them in the wood. However, with that said, a good "recipe" will give you both.

I know this is an older thread but I thought I would share my opinion on why so much carbon buildup on the piston crown........from the castor oil in the Klotz. That stuff burns real dirty but is a great lubricant.

Could be. But I also run Blendzall a lot, which is a straight castor oil, and it doesn't leave those deposits.

Turds should be tapered Jasha.........you know that.
Otherwise door slamming damage could and most likely would ensue.

I was at a spring GTG at Heavyfuels's a couple years back and I seem to remember watching a 440 make my 7900 look pretty silly. To say the least I was impressed. Seems to me, and for those of you that were there please correct me if I am wrong but that saw was built by TreeMonkey. Seems like there was a vid of that in that GTG thread.

Treemonkey builds a hell of a strong saw. The guy takes a back seat to no one. :msp_thumbup:
The first ported 066/660 I ever ran was a saw that Scott built. I was impressed enough to try my hand at ported saws.
