    how about a Oklahoma,AR,MO,KS,TX,+IA GTG thread?

    The people who do drywall for a living hardly sand at all, they sponge the mud when it's just setting up. With quick set mud and the sponge method they can do all the required coats in a day.

    Should i grind a 572.

    My notes say they are at 102.25° exhaust (155.5° duration) stock. I raise them to 100° (160° duration). They seem to turn out well.

    You can work the upper transfers towards the intake a little. But the actual intake doesn't need any work.

    Should i grind a 572.

    There is not any room to widen the intake, the piston limits how wide the port can be. I leave the intake alone as machine work adds the necessary duration. They do like a little more ex duration than stock and there is room to go wider there.

    The Metalworking Thread

    Generally my stuff gets enough use it stays covered with it's own lubricating oil or coolant enough not to have any rusting problems. Back in the day at the machine shop lesser used machines raw surfaces would get wiped down with wd40 or marvels mystery oil.

    Bar shop

    They've been out of business for a while, the owner has passed away. The building they operated out of is dilapidated and graffitied on google street view.

    I used an internally reinforced cut wheel made by Norton I got from McMaster-Carr, it worked for 63g but I had to dress the wheel down for 50g. Now I can't find the wheel on McMaster anymore.

    Husqvarna 572 build.

    The stratos open when the top of the piston cut out is above the bottom of the upper transfer, so you've already added a ton of strato timing by dropping the jug so much.

    simington grinder

    Completely disassembled the motor, measured the run out of the shaft between centers on the lathe and used a press to straighten it.

    simington grinder

    It can probably be straightened by any reputable electric motor shop. I've straightened shafts on many silvey motors.

    543 wtf

    The carbs on those NH843's are junk. It will likely not run very well.

    Buyer Beware ????

    For reference here is what I leave between the ports. The photo was taken before port beveling.

    Buyer Beware ????

    It appears that the transfers have been raised less than what was cut from the squish band as well as the terrible grinding on the transfer port divider.

    90cc class saws which one is the current king of the class?

    I have it back. I did some updates to it while I had it apart and it put up some impressive numbers on Joes dyno before eating another big end rod bearing.
