Welcome to GTT! :wave:

Did you get any other attachments?

no other attachments to be found. I seen a original brochure on this unit on ebay. it shows pics of the other attachments. very neat . I will try to post pics of my machine at a later date , as I let my brother use my camera for his vacation . so have to wait to get it back to take the pics and post them .

 

does anybody know what kind of spark plug i could use in an old briggs and stratton motor like this . the plug thats in it has no name on it just a old number  W14ju  japan plug . still works though

All of the correct plugs are 14mm threads x 3/8" reach.

 

Long plugs (13/16" hex) = Champion J-8 or Autolite A7 .....If burning oil, a slightly hotter plug can be used such as Champion J11 or Autolite A11.

 

Short plugs (3/4" hex) = Champion CJ-8 or Autolite A7NX

 

The original plug in your B&S engine of that era would be the longer style, and was probably equipped with a Champion J-8.

Power Pak Update!

 

Got everything back together on the Power-Pak yesterday. It's so simple I had the thing together in less than an hour :D

 

 

There is one small problem though... Wont start! 

Generally I make sure the engines run before I tear them down but the points push rod was frozen in place and couldn't test for spark or fire without having to totally dismantle the engine.... I think its the coil

Sparks great sometimes then other times hardly nothing at all. Points and condenser have been replaced so thats not an issue.

I didn't have any other coils to test with. I was able to have it run about 2 seconds  so I know its not a timing issue.

 

Looks like the coil is NLA and no one that I know has replacements! The ones on the 8B's and similar are all mounted in reverse compared to this one Looks like I may have to pony up some $$ and hopefully get a NOS one from one of the dealers on the web.

Played around with it today and went through all the used coils I had laying around (3) and all did not make the engine fire!

The coils were in unknown condition but thinking the odds of 3 coils being bad were slim I figured maybe I missed the timing mark on the camshaft so pulled the engine to inspect and I did have the cam timing marks where they should be.

 

Going to have to get a new coil and see what happens.... if that dosent work I'll be out of ideas.... I seem to be having bad luck with ignition systems this year :wallbanging:

On the B&S engine, the points are operated by the crankshaft, not the camshaft, so you would have spark even if the valve timing was wrong.

 

Is the top bearing surface of the block worn, allowing the gap on the coil to fluctuate?  .....Can you "rock" the crankshaft in the block enough to affect the point gap?

 

Is the plug wire on the 291617 coil soldered on, or is it molded into the coil?

 

Flywheel magnets good & strong?

 

Points grounding out? 

 

Replacement condenser bad?

 

Is the plunger sticking in the block as previously?

 

With the luck you've been having with coils, you need to invest in a coil tester. :D

 

What model B&S?  ....6BH?

I was getting spark occasionally and figured it may be out of time since It wasnt even firing when I put some gas in the plug hole...

I used my ignition tester with the LED lights and observed intermittent spark when the plug was in, sometimes no spark at all.

The lamp on the tester was orange and according to the chart that means weak igntion system.

 

the plug wire is just soldered on, I even replaced the wire!

 

Nothing was worn on the engine, I installed new rings and seals as well as lapped the valves.

 

Its an 81702 Model

Mine is missing the clutch lever. Would you be willing to post a few pictures of how it mounts up and maybe an overall dimension so I can make a replacement.

Power-Pak is together!

Stole a magneto off another engine I forgot I had laying around and she fired right up!

 

Just need Decals

 

 

-Antiquetractors:

Took some pics of the clutch lever but forgot dimensions :wallbanging:

Do you have everything else underneath such as the springs to slide the engine back and forth?

Very nice, Brian !!!  :thumbs:   :worshippy1: 

 

Was there a front cover to keep dirt & debris out of the belt/pulley area, or were they always open.?

 

What's next to be done?

Thanks!

The front was always open.

I did engage the tines but didnt let them hit the dirt as I was too afraid of scratching them :D

I bet it does a good job tilling as the tines spin at a pretty good pace (Alot faster than the tubeframe tillers)

 

Did you guys ever sell any Power-Paks at the mower shop?

 

Now that it looks so nice, I really would like to find the Mow-Pak for this.

So if you see one anywhere let me know!

 

Dont know what will be next. I try to restore 1 a year but may take a break and concentrate on attachments next year.

No, we never stocked or sold any Power-Paks.  .....We sold a lot of Toro Power Handles and attachments, instead.

 

We did stock & sell Bolens Mustang tillers, though.
