Blazer(Tote Gote) Briggs Magneto

[Butterfingarz]

I inherited a Blazer mini bike that has the original 3hp Briggs and Stratton 1962 motor. I am trying to get it running first before a full restoration as it has sentimental value to the family.

We are not receiving a spark at the plug. I have cleaned and adjusted the points, new spark plug, new throttle cable and housing, cleaned the carburetor, tank was luckily empty and put new fuel in and made sure the lines were clear, and adjusted the magneto to be a business card away from the flywheel. The magneto measures 5.5k Ohms from the spark plug clips to the engine ground. Still no luck. No visible spark when the plug is out and grounded on the head.

I wouldn't mind converting this to an electronic ignition but I can not seem to find the correct kit. The model engine is 80302. Thanks for any help you may be able to provide!

I grab a 30 buck 2 or 3hp Briggs magnatron ignition edger and grab the coil and flywheel and solve these problems this one had the swap.

The original magneto has a 4 bolt square mounting like on the image in this parts catalog.

Page C Top center image. Original part numbers looks to be #291617.

Creia - The part number you provided doesn't look like it replaces the discontinued original number. Any suggestion you have would be helpful. Thanks!

I've dealt with a few of these real old ones.. that is indeed the old 4 post coil otherwise know as unobtanuim in complete form. I was lucky to get one from across the pond on ebay.uk from Meadowbrook. I did run across a replacement armature only last fall without the laminated frame, seemed easier to find..I will grab the number from it later today for you and post it up..

Thank you. I wonder though the #591420 part mentioned earlier would work with only two bolts? This part seems readily available and doesn't break the bank.

Well as luck would have it the box top is missing and has 291617 written on it’s side. It does match up to the coil on my Gote..
I did poke around and there is one in the land down under ending soon on feebay..It‘ll be hard to find one on this continent..link below..

I'll give them a call since E Replacement Parts doesn't have any suggested replacement. Thanks.

I'm going to order the #591420 electronic ignition and try it out. Although the magneto I have a 4 bolt pattern, I hope the new one with 2 bolts will still work with the bottom two bolts. I may not be able to keep the bracket with the plastic flap on it though.

Well I got the bike running using the original magneto and points setup. There was a small 18awg wire on the backside that looks like broke off the top of the magneto.

The new electronic ignition did not work as the legs that pickup the electrical current over the magnets in the flywheel was a different angle to the flywheel. For example the flywheel is a 8" diameter, the new electronic ignition legs were for a 10" flywheel and weren't close enough to the flywheel to pickup the magnetic current.

I need to really deep clean the carb now because it will only run with the choke on.

Good you got it running.This has the same 1/2 choke on for running. Our orfice tube is more likely plugged at few holes.
This one has had the 80s 90s electrotron coil flywheel swap..good spark but boggy carburetor. ...
Shown in photo 2 is a 10 buck non running Briggs to do the coil swap..
