Firestone 1946 3.5 information

[Carl Wassersleben]

If it wasn’t old and sorta weird, I wouldn’t be working on it. Sigh. A 1946 Firestone 3.5 followed me home today. Only numbers I can find are 462 and 1881 on the base of the cylinder. Its rusty and stuck, but the crank and lower unit all turn. I’m not afraid.

I am sure I will be searching for mag parts, coil, points whatever I can find, modify or fix. Any info or help is as always, appreciated.

Maybe;  maybe not Carl.  The magnetos in those are very reliable at least in my experience.  Is the flywheel off?  Is the coil a brown shellac-looking coil?  Probably good.  Clean and polish the points and replace the condenser if you have a good spare and you might just have spark.

For what (little) it’s worth https://discount-marine-parts.com/ob_firestone_1.html shows that 133-6-462 was a 1946 3.5hp with rope start

I did remove the flywheel. Cleaned the points, coil looks great, replaced the sparkplug wire and nothing, I installed a condenser I use for rebuilding Elto coil assemblies and got intermittent spark. I attribute that to a poor; temporary test condenser install. led me to believe that i need a new condenser that I can make work in the Firestone mag.

Thank you for your reply

I found what looks like a suitable replacement at the Brillman company. They sell all sorts of wonderful Ignition parts for all sorts of antique equipment. That’s where I get my spark plug wires and period correct cloth covered primary wires. Great stuff. Nice people to deal with
