No absolutely nothing about. Does anyone have a repair service/manual for the MC9 for purchase or download? I’m also going to need
a overhaul gasket set for the engine and carburetor. I think I have a block / crank bearing issue because seems to have too much
crankshaft lateral. I haven’t taken it apart yet because I lack specs and gaskets. Thanks for the help!

Speaking of colours, my white helmet needed replacing...

PB - I have been using 4mm cord I get from Baileys. I would avoid hardware store type cord, even if you have to go to a small engine shop and get some actual starter rope.

Bob - I'll check my replacements and see what the diameter are.

Thanks Mark.

It's here

Probably it's original hard nose bar.

By the handle wear it's had a easy life. Starter screws are gunna need some M6s.
Av seems ok.
Good air filter and plenty compression

Edit...

Bottom screw is snapped.
Top left is OK.
Too right. There is no too right???

Metric.

 

[Jethro 2t sniffer]

Metric.

Yup the m6 runs straight through whatever random size the starter screws are

 

[heimannm]

Original screws were 8-32 for the starter cover and the three longer screws to hold the flywheel cover on, go to M5 if you must. The one at the front of the FW cover and the one into the special stud on the coil are 10-24, hopefully the one in the stud is still O.K. as that one might be tricky to change over being a blind hole.

Heli-coils would be a better option if you need to make repairs, not a lot of substance around any of those holes to allow you to expand them to the M6 fasteners.

Bob - does this look like it would work? I think I can find some rivets to go with it.

I don't mean to be an ass about this,but Mac DID use metric on it's saws.The 300 seris used a 10mm.bar stud nut & on the chain brake too.IIRC,the 600 series bar stud nut is metric as well,I don't recall the size (14mm.?),although a 1/2 in.socket will work.

Jethro,you should find a conversion chart that goes from SAE to metric & vice versa.Plenty of 'em out there on the web.

 

[bob kern]

It is funny how there can be both on the same equipment. I've seen it.

I was finally able to have my knuckklereplacement surgery yesterday after testing positive for Covid last month.I had a nerve block on my right arm so I was awake through the surgery & was able to talk with the doc as he used his surgical Dremel tool to cut through the bone to remove the old knuckle.He had a small bucket of "knuckles" to choose from & trim them a bit to fit.The entire procedure took less than an hr.I awoke at 4:45 a.m.t o find that I could move my arm again & along with that came the pain.If anyone could've seen me wrestling with my T shirt,trying to make breakfast,& trying to open a can of cat food for my cat you'd have thought it to be quite entertaining.Now it's time for the healing process.
