I'm very impressed with those pictures of the bore. Interesting evidence so far. It could be saw dust from being in a saw guys shed. You'll find saw dust/chips on or in pretty much everything I own.

I kart gets an absolute thrashing to end all thrashings. It very well could of done a 5 or 10 hour stint before a rebuild and then perhaps they put something else in and chucked it on the shelf and it never got used again. A kart engine 10 hours could be a saws 1000 and would explain why its so mint on the outside.

Never really will know but what we do is that thing will rip a saw chain along very nicely indeed:)

Don't give me the credit! This phone has a 50 megapixel camera in it.
Apparently it can do one thing properly.

It is DONE!! MacHalla is complete! Trust me when I sank the last screw in the last shelf I was a bit overcome. Now to clean it and move the rest of the goodies.
I even christened it with a NOS sign...View attachment 1066288View attachment 1066289View attachment 1066290View attachment 1066291View attachment 1066292View attachment 1066293

Get yourself a paint sprayer, then spray all the shelves with chalkboard paint! Then you can scribble and erase as inventory changes !
Just an idea you don't have to take me seriously.
 
Lock the pulley in the housing with a #2 phillips screwdriver through the notch in the pulley into the spring retainer hole, then turn the clutch nut CW to remove. A large square shank screwdriver is one possibility.

They can be quite stubborn, I made a simple tool to fit my impact wrench to break them loose.

Thanks, i did that with a little heat and got it off. The plastic bushings have some junk behind them and i cleaned the hole and put it back together and it is free. Appreciate the help

@heimannm Mark didnt some of these have a metal bushing also. I might be confused but I tore some down a few years back for 125 recoil screens and other parts and think I found metal shaft bushings in some.
 
kid - I struggle with the flooding issues on mine as well, seems I need to turn the H jet down to less than 1/8 of a turn open to get it started then open it up again once it is running. McMaster-Carr has spacers if you need one.

Max - I know some of the 10 Series had brass bushings, I think some of the RH start saws may have a well. Some of the earliest LH start saws like the 1-40/50 had a brass bushing instead of the nylon ones, the starter shaft with the ratchet was one piece and was fixed to the pulley with a roll pin.

North East Tennessee MAC Report

Beautiful day today in North East Tennessee with a low around 32 degrees. However, the ground was too wet to gather wood and it was a bit too windy to cut, so I have no MAC action to report today. The temperatures are supposed to drop over the next two days before warming.

056Kid's posts got me to thinking about my blown kart saw and my other unfinished projects. With nothing to do outside today, I decided to fire up the wood stove in the basement to moderate my electric bill and to take some time to think about my projects. I reached no conclusions about the kart saw - do I have the block re-sleeved, swap in my spare 101B, or sell them both as is? My bored ten series with 240+psi has sat for over two years now as I contemplated how to best lower the compression. Some months ago, I decided to leave it as it is and see what happens but haven't assembled it. After busting my PM700, I toyed with putting the bored power head in a non-A/V ten series "frame" as I would only be using it for short periods and the A/V is added weight. The first hurdle I encountered was the 82cc oil tanks have a mount that would hit the smaller gas tank. Not wanting to cut up an oil tank, I thought I would see if the 7-10 oil tank I got from Mark to fix the 700 would interchange. It won't - crankshaft channel is two shallow and cylinder bolt pattern is different. Being more curious than focused, I turned my attention to the differences between the 700 oil tank and the 7-10 beyond the obvious of the former being aluminum and the later being magnesium. I did not note a lot of differences beyond the 700 being beefier in spots. I then weighted them on a postage scale to find that the aluminum one is 6.5 ounces heavier - more than 50% - 17.5 oz for the 700 with studs, manual oiler, and auto oiler gasket in place compared to 11.3 oz for similarly equipped 7-10. I don't know how much of the 700 is aluminum parts versus the magnesium on the 7-10 but a lot of extra weight could added up quick. Anyone here know the reason(s) MAC went to aluminum?

While I am seeking answers, does anyone here know why on my newer computer I get ads that blocks the use of the search function and blocks checking alerts, when neither my old computer or my phone gets the annoying ads?

Thanks in advance,

Be safe.

I can't help with anything Ron, but in theory you can block (some) ads by paying the extra $20 a year or whatever the rate was. I paid, but have no idea on how to go about blocking the ads...

I have the same issue Ron. No remedy as of yet. I have not tried a different browser. That could solve it. I run Safari. I am a a Mac man in multiple ways lol. If it continues the issue should be reported to the Webmaster or IT here.

Thanks. Old computer is Foxfire.

Thoughts or opinions on the answer to the MAC question?

I honestly don't know. Ron I could add speculation and conjecture but otherwise I am no help on this one.

A bit confused on parts of your post. are you trying to put an 82cc A/V motor onto a 10/10-700 tank?
