Guys, the $21.50 is for a Complete Kit

As Ben mentioned, suggested list for B&S is higher than that

Don't mind me, guys!  .....I just get "sticker shock" at today's prices. :wallbanging:

 

This old fart remembers selling the 391681 diaphragm for $1.85, but that was quite awhile ago! :smilewink:

 

Bruce, I try to ignore the 1970's paper price lists I find when I dig into my dealer manuals.

 

They give me heartburn. 

 

The RETAIL prices there are a quarter of what my cost is now as the highest level Briggs dealer.  :wallbanging:

I dont remember them that cheap but I do remember buying a whole bunch of them when they were around $3.

I do not understand Briggs. About 5 years ago I had to work on a 3HP horizontal, and among other things I needed a governor spring. The local idiots had one in stock, yeah but I still remember the S#@t  that I gave the guy, when he came back with a price of $17, he tried to get me to buy a whole new Honduh POS instead of the spring. 

he said that Briggs would rather guys like us scrap the old engines than to put anything into them. so they make the price on stuff like that more than ridiculous thinking that "nobody will pay that price for such a small (but necessary part) and will buy a new engine instead".

 

Used to be (again back in the 80s sometime) when they would obsolete something out they would drop the price to pennies vs what it last sold for as a good number, back then I would make sure to buy more than 1 of what ever it was at that point to be sure I had one here the next time..

 

I still have a few 92000 series engines around, and I now  have a few  aftermarket 391681's  (Stens, I think they are) (cost me about what the real thing used to back then) that I will try my luck, with when the time comes

Considering I can get parts I am a happy man.  Still better than anything I can pick up unless I sell a kidney to fund it.  Those are already gone with the old car projects that are in a holding patter.  Come on Iowa lottery...

Got home from a trip to visit fam in Ohio and the kit was in the mail.  I hope to get the carb rebuilt and machine cleaned up over the weekend.  Thanks Doc!

Carb rebuilt and installed but the throttle does not work. Time to dig out the manual and follow it. My lack of knowledge of Briggs engines shows.

Spent a bit of time with the old Deere this afternoon.  Decided to check out the governor as I thought it might be the source of the problem.  I was right.  Piece #11 was bent.

After a bit of rebending and adjusting the carb it runs great.  Not bad for a total of $75 including parts and the machine.  The self-propelled makes pushing this monster much easier.  Now I need to figure out the throttle control assembly as time has not been kind on the plasitic mount and the cable.

Did some "trying to wake up" research and found the control assembly is NLA.  I will pull the assembly apart and see if I can free things up and get it working better.  Not really a surprise either due to age and low demand.

All right, I picked up a universal throttle kit at the local Theisen's farm and ETC store and adapted to fit.  I am happy with the look and function of the install compared to the original pices which did not stand the test of time.  The machine starts great cold but is a bear when warm.  It Runs great when warm with the air cleaner removed but will not run when it is reinstalled.  Also, it seems as if the choke is not opening up when warm.   I have followed the service manual but am sure I am missing something. 

 

Any suggestions with this beast???

This is going to be a dumb question but have you replaced the foam element? These disintegrate over time and may be restricting your engine from drawing air and fuel.

Did you preload the diaphragm when installing it?

Umm... since I do not know what this "preload the diaphragm" means I will say no.  I followed my service manual but might have missed something.  As I mentioned early in the post, these Briggs are new to me.
