My wife and I watched our church service online yesterday morning at 9am I was then going to go putter with my O&R but things started to unfold really fast, we had an idea that there was some victims but not expecting what was to come . By 2:30 pm the shooter was shot and killed by RCMP and we started to here some online chatter of the extent of his 14hrs of terror. We went to bed last night knowing that by the morning we would know friends or family connected to this tragedy. I was correct, we did. Still possible not all victims found yet.

Hi guys!! I’m pretty excited. I got carb back together, diaphragm assembly together and carb on. Hooked up gas line to carb and little hanging bottle with mixed gas 24-1, sae30 HD as instructed on side of gas tank. First push of primer button and gas went up the tube, very surprised how far it actually moved, about 5 pushes took it up 16” of gas line. It doesn’t have the exact Spark plug in it but all I have right now. No fuel tank on it or exhaust. I gave it a couple extra primes after fuel reached carb. Put choke on, second pull it kicked!! A few more pulls, monkeying with choke a bit, kicking a bit more each time, it started!! It seemed to want to take off and rev up pretty  quick so I just shut  it down. Just to be safe.  I wasn’t really sure where throttle was. Anyway pretty nice to see it run, it might never run again, I don’t know but I’ll get right plug, finish cleaning it all and put completely back together. Then try it again. 
   A couple things though. 
   Should I go with a different gas mix?
I have 2 stroke STIHL mix, not synthetic.
  I attached 2 pics, the older O&R has a little filter in gas tank on end of fuel intake. The one I’m working on now has nothing on fuel intake.  What options do I have for this one, I obviously need something, correct? In the pic you can see a hard drop of oil on bottom of tank, the tube is about 3/16” above it. 
 
  Thanks again

O&R Carb Repair Tutorial
 
The tutorial below was copied from the original thread from the old forum saved by the internet archive, tutorial courtesy of laserscottman.
 
Here we go! The first pic in this thread shows how it all began. Following are the things I encountered along the way, during cleaning. After receiving the new diaphragm in the mail, I fully used Webhead's excellent instructions to reassemble the Primer/Diaphragm Valve Assembly successfully, with the following pictures detailing how I understood it. Got a block of soft wood and gently screwed the valve body down to hold it still to work on it. Fashioning a suitable 'filament' to thread through as shown, the filament is then used to lift the Diaphragm Arm Spring ends to allow the Diaphragm Roller to be laid in it's place at the right time in the assembly sequence. Then the Disc, Diaphragm and Cover are assembled.

The gum package is just a dark background to show the loop on the filament end to better grasp it. A non-magnetic pair of tweezers helped lay the roller in when it was time. The dental tool made it easy to pull/lift/move the Diaphragm Arm Spring to the various positions during assembly.

This is a detail view of how the spring will end-up over the roller in the end. Good practice to 'feel' how those spring ends will react to the filament tugging them.

Now the Spring is lifted and stays at this position, to allow for installing the Diaphragm Arm. Note that the Roller and the Diaphragm Valve Ball are in place before the Arm is laid in place.


The next part is tricky. Using the dental tool to push the Spring over the Lever toward the Roller, you must help the Spring tips over the Roller by using the filament, and helping the Lever to stay draped over the cross pin, until the big end of the Spring is seated well in the Lever short end, and the Spring ends are capturing the Roller. All this is done kind of simultaneously, according to the position of the parts. You will be glad you only need 1 hand to hold the filament, and that you have a fine tool like the dental tool!

Perfectly aligned, and will stay if the Lever Arm is not lifted all the way up--which is what got me in this jam in the first place! Now, you must carefully remove the filament. I cut the long end near the Lever Arm, and gently removed the filament.

There it is!

Then you can sequentially assemble the remaining parts. Be sure to install the screws with fingers, loosely, to avoid bunching up the Diaphragm in the threads. Don't overtighten the screws; the cover can be warped a bit, and may "bite" through the rubber Diaphragm.

This assembly then gets the thick Gasket and Diaphragm Valve installed with the clear plastic valve against the body, covering the hole. This is a one-way valve that opens and closes rapidly during operation.


The Needle Valve Assembly and the long screw mount the Primer Diaphragm Valve Assembly to the "Quadrant" Carburetor Assembly (carb body). Remember you are tightening a hollow brass part to an aluminum part! Snug, but not overly so. Kinda looks like the Starship Enterprise, don't it? Now this Dinosaur fits in among his smiling friends!


Little, but MIGHTY!

Many thanks to Webhead for his patient guidance and sharing of parts and resources! And thanks for this forum! Cheers!

"One thing that Scott mentioned that is VERY important- do not over tighten the brass needle valve assembly! I use a nut driver and give it a slight snug. In my earlier days, I snapped off two or three by using a 5/16" wrench. With a wrench, it seems like you always want to give it a little more and then snap!"   David   Edited; Nov 28 2014 to add the pictures to the forum. Dec 07 2020 to update diaphragm sourcing info.

I have many 4 cycle engines that smoke when using straight 30w, but no smoke when using 10w30. I also have engines that run poorly on 89 octane ethanol, but not on 87 octane non ethanol. I think an engine likes what it likes. Great job on getting this kit back in shape.

Here are some pics of second unit. The pull cord cover is oxidized a bit but appears not to be damaged. This one says “110/220 “ as well, maybe they are all the same, I don’t know 

Thank you for the reply, very helpful.
Here are some pics of one, maybe you could identify the small piece I found in the box it came in. I also would be interested in any parts you could lead me too that I might need to rebuild 2 carburetors. Could also use a new black receptacle. 
  Again, appreciate your thoughts .
