A Solo 667 Build thread

Check again... you probably have a 285 cylinder.

Must be I did pick up the 285 cylinder... I will check the 480 cylinder I have for fit when I get home. Thanks for the idea.

How far off is the installed height with a 390 55mm jug and piston?
That would be easy to acquire but a lot to rework the case and cylinder bottom. Just thinking out loud.

Send me one and I'll tell ya!

No gots...sorry Charlie.

A 460 cylinder is shorter than a 395 & 660. They make a 54mm big bore.

I’m along for the ride.

Give this guy a call. He has some 690 and 667 parts. He might have the 690 jug your looking for. He was/is one of the few solo dealers in the USA.

Little update, not much has happened lol.
I'm starting to come to the conclusion that I'm biting off more than I can chew but I'm going to keep forging on and course correct as we go.

Neither the 395 or the 066 BB cylinders are going to be a good fit, evening if I made an adapter plate. The cylinder on the Solo is significantly shorter than both the 395/066BB cylinders because the case is acting as the lower transfers. I estimated the 066 cylinder would have to be decked at least 0.200" before I even add an adapter.

For those reasons I've decided to look for an alternate P/C. It's still not going to be bolt on but should get me a lot closer. The donor saw is a Solo 690. I have short block with P/C on it's way.

The challenge is still going to be fitting the 690 on the 667 case. They are similar but not the same. Also, the 690 has a 42mm stroke. Luckily is has a 12mm wrist pin and a 55mm bore so a 390xp piston might be interchangeable if needed. Of course the 690 crank comes with the short block so if I need to use it I can. I already found the bearing journal on the two cranks are the same diameter.

690 crank has a future in the 667?

Possibly. I'm going to see how the 667 crank works out first.

Those some big lowers. You sure you’re not working on a 250R??? Lol

I'm not sure. Got a spare cylinder to send me to compare? I promise I'll give it back...when I'm done.

Just stroke it buddy..... you know you want to.
Ahem..... the chainsaw, the chainsaw!

That thing sure is beefy, yes the chainsaw.[emoji4]

Seriously though that saw is built.

I'm not sure that a 390XP piston would be an option with either crank (667 or 690). They both use the 12mm wrist pin with a very thin wrist pin bearing and the 390XP piston uses a 13mm wrist pin.

As I said before, the 661 jug is shorter than an 066. Right around .200” if I remember right
