Hey Guys, I have a Mcculloch 790 that had sat on the ground far too long and I am in need of a Lower handle section and an upper handle section, which I believe includes the gas tank as well, the inner recoil assy for a right hand and a coil. I'm a buyer not a looker so if you have anything let...

Hey Guys, I'm working on a KB7 for a buddy of mine, it fires but the timing doesn't seem to be right, it acts like its back firing then rips the handle out of my hands, is there timing adjustment on these in the mag? On some of the old outboards I've worked on there was a advance/retard lever...

This is my goal, I know I'm literally lightyears away from the knowledge and skills of Timberwolf, but its good to have goals right?

Ok, I'm not totally sure of the numbers I'm looking for yet so that helps a lot. I haven't raised it any yet, I haven't changed the timing but I did flatten it out and open it up some on the roof. My plan is to play with blowdown numbers until I go too far, then back up and use those numbers on...

I'm still having trouble finding the time to get the machine work done for the mandrels. We had a big maintenance shutdown at the mill I work at this week, between that and the family it's hard to find time in the shop. I have to travel to the states next week and then I'll be gone for another...

Its a 24" Slim Line Mac Bar, there was a batch of them on ebay recently. I'll take a picture tonight. Came with the original cardboard, the seller stuck shipping stickers all over it but they came off easy enough with a heat gun. The bending over is exactly what I'm trying to not do by running...

I'm leaning towards the same, but I hate having new stuff and not being able to use it!!!

Yeah, Its funny how you spend twice the amount of time on building tooling and setup then you do actually machining the part in the first place. The good part is, once the sleeve is built its done and you can use it over and over, until you decide to work on a different saw, then its back to the...

God, what happened to that cylinder? I'm working on fixing a PM700 parts saw I got. I've found most of the parts I need, I took a compression test and it showed 100psi, seems like it has more compression than that, so I checked another saw and it also seemed to be reading much lower than what...

@drf256 I can't thank you enough for taking the time to post all of those pictures. That's great. One question I do have is when machining a piston are you using a jig chuck it up or just chucking the piston alone? I actually took the old piston and turned it flat this weekend to use a sanding...

The ring on the piston is from some flashing left on the inner part of the squish band, I think the photo does make it look different. It wasn't like that when I originally put it in. It is a 44mm and with no base gasket and after I sanded the squish band back I'm at about .012 squish. I sanded...

Will do, thanks dude!

Here’s what I did this afternoon. If it doesn’t work out no biggie, p&c s are cheap for this. I flattened out the exhaust roof, but didn’t change timing at all. I widened the intake port And sanded the squish band, seems like they’re was a flashing lip towards the expansion chamber. Thanks for...

Wait, they make bigger saws than this? I have big saws, but I like working on two strokes and I’m trying to become more familiar with port modifications and tuning.

I cleaned up the squish band with sand paper As soon as I can find a piece of stock big enough I plan on building a mandrel for hand cutting squish bands. Matched the port opening to the new port size, drilled two half inch holes through the top of the cover, that was just a half ass test, I...
