Project Stumpbroke Solo 694

[Stumpys Customs]

This is my current project I have goin on. A big red SOLO 694. Same thing as a Dolmar 9010. This is a ground up build with new bearings, seals, top end, oiler rebuild, and porting.

This is how I received the saw. In a box torn apart. This should get me over being spoiled with the new saws I've been building lately.

Here's the lower end ready for re assembly.

This was the easy part.

Here's the oiler ready to go back together with some new guts.

I decided to put the saw together & run it stock to get a vid for comparison.

Stump, looks great from this end.May I suggest that you use a soft wood like Pine for your videos like some others do.Makes it easier on the saw also, Ken

After running about half a tank through it I tore it back down for some grinding. I think these saws are about the easiest ones to remove the tank. After disconnecting the throttle cable and fuel line all that is left is four mounts. Then the case lifts right off of the tank. No twisting & holding yer mouth just right.

The rubber mounts thread into the case, then there's a coarse threaded screw that goes into the tank. Would be awesome if they had springs instead of rubber.

Got it all tore down & ready for some fun.

I won't be useing the OEM piston for this. I decided to use an 064 piston instead. I don't have any pics yet of them side by side. More on that later.

Compression before the second tear down, and after?Base gasket?Splane this one, What drill is missing the chuck? I am enjoying this one.Something of a different flavor than the usual threads floating about, Ken



I will get some ribbing from this....

After some machine work on the piston & cyl I have the cyl laid out for the porting.

Intake side

These have some nice big transfer runners and are angled to direct the charge to the intake side.

The exhaust port will only be getting some widening since the port ended up right where I wanted it after the machine work.

Thats all the pics I got for right now. I have the cyl half ported right now & should have this thing runnin tomorrow.

COmp was right @ 140psi after half a tank on the new top end. I expected it to be higher. I'll be useing the stock (new) base gasket. I don't run saws gasket-less any more. I machine them to get my squish tolerance with the gasket. I bought the chuck without a drill attached to it. I hope you enjoy this.

I was eager to dive into this build since it was a saw that doesn't get allot of attention. Good well built saw with a small bore (52mm), long stroke (42mm) combination. Not very high revving, but have a lot of grunt.

Does anybody notice something different about the bar mount on this thing??

It has two sets of threaded holes for the studs. Would anybody have a clue as to what the purpose is for the other set of holes?

Uhhhhhhhhhhhhhhhhh NO.

It's for a different set of bar studs and different plate. D009 & D033 Oregon bar mounts. Original PS-9000 used the other studs.

Thanks, I had an idea it was something like that. Just odd that they done that.

That should read "D033" not "D031"
