My father in-law picked up this treasure at an auction a few years back. It's been sitting since along the back fence row getting swallowed up by the weeds until we started clearing off the fences again & drug it to my shop. I think he got caught up in the bidding & paid way to much for it, but I told him it's not a total loss & I could bring it back.....with a lot of parts! Unless I can find a correct Briggs for it, I'll probably throw in a spare K181 I have on the shelf. Currently in the process of tearing it down,my FIL will paint the tins while I do the mechanical work. Check out the inspection window on the backside of the engine!
I just put a 'Stens' universal ignition module on my SB-421. Its finally showing a spark, but it's faint. Ohmed out the mag and found it's shot (42,000 ohms). I guessing the points/coil and mag went at once? Since it appears the universal is working, i'm looking for a magneto for this model, if anybody has/knows of one. Since I bought two universals, I'm looking to attempt to see if one will work on my 552/H55 engine. Has anyone done this on the diode system yet? (I posted this on "engines" board also)
