Ok, that’s what I figured. I’m going’s to check one more source. I have the guts to another engine that might be old enough to have the plastic bearings. I’ll pull the induction unit apart later today to see if it has one in decent shape.
It took me awhile to track down a source for the diaphragm material in the right thickness. I ended up going with a material from Alpha Engineered Composites. It’s a Fairprene product code WFP-B2N1.
Would it be too risky to re-use this bearing? I don’t plan to run the engine much and since the bearing cage is all confined when installed I’m wondering if it might still work even though it is cracked. What would you guys do?
The Groomer string trimmers (weed wacker) were made in the late 1970's by Advanced Engine Products Incorporated (formerly known as O&R), this was towards the end of AEP (O&R) as the company was dissolved in 1978. Hopefully someone will find a complete trimmer one day.
I found one and got all excited but the owner wasn’t interested in selling it.
I aquired one, I found it in my friends dead neighbors barn I was wondering if you could help me find a new carb diaphragm or if I can make one and how to do it or any info would be a great help thank you
Welcome to the forum! You have us drooling over the fogger, that is a really neat tool. PM me and I can also help you with a diaphragm if someone else hasn’t already got you fixed up.
I’m certainly not opposed to keeping and re-using the plastic ones, just didn’t know if they were known to fail frequently. Two of the ones I have look to be in ok condition. There is one though that the plastic has cracked all the way through so I’m guessing it should probably be replaced.
Here’s one of the shafts and it has a flat washer with the plastic bearing. If I switch to a metal bearing I’m wondering if this washer will still work or if a different set up is needed.
Thanks for all the research on this David, very helpful knowing the progression and changes in part numbers.
Do do you know if the bearing swap is all that’s needed or are there any spacer washers or other pieces requires drivers to fit the metal bearings with the various shafts? I will try to add a photo in a little while of one in particular I’m thinking about.
I have the a-27-4 in the new metal bearing should be a-27-17 used
I have the a-27-2 in the new # metal bearing a-27-18 only in a new one
I have a-27-3 in a used one I don't see an old # for that one
If you need one let me know
If you have a couple minutes can you send a photo of these? I’m curious to compare the design of the metal to the plastic ones? Wondering if I can find a metal version off a donor engine or something and it would help to have another visual reference since they won’t be NOS with part numbers.
Came home this evening to a really nice surprise - this super cool original owners manual and parts list for the Clinton K-150 / O&R outboard, THANK YOU VERY MUCH Terry (Just O&R)! This is awesome, always fun to have original literature and manuals to these O&Rs! Very much appreciated that Terry!
That "nub" looks like a sheared key to me but there was another guy before stating his flywheel didn't have a key way. The key only lines it up for the timing and the taper is actually what holds it in place. Is the crank slot normal?
Now I see what takes you guys so long. All of those neat little compartments for parts takes time.
Wish my organizational skills were that good
Yeah, I made the mistake thinking it was sheared and initially tried to remove it and that’s when I found out it was part of the design.
I use to be more organized but now that I’ve done a few these you start to know each little piece pretty well.

I hope he knows that the shaft seals are different in these early engines.
The carb with the red needle valve, I'm sure I seen that on the Creme Lure generator, mine doesn't use a Type 115 117 though.
David
The seals are different sizes or design? I haven’t removed them from the housings yet. I was also wondering about the little red cap on the needle valve- I hadn’t seen that before.
