points plunger

[pbrenner70]

Does the points plunger on a 10 HP cast iron briggs just pull out? I am replacing the points and I would like to replace the plunger just because after 30 years I think it could use a new one. Does it just pull out or do you have to dissassemble the engine? Thanks

#65279;No they don't just come out. If you read the manual, you destroy it removing it. Replacements were available a few years ago but very expensive. If I remember right,some of these engines had a phenolic tip to ride on the cam and they ware / come off. I have a 14 HP and the plunger just opens the points. The gap is only .001" or .002" but she runs ok.

Glad I asked before I tried removing it. Thanks to everyone on this forum. I ordered one from M&D mower supply but I guess I will have to cancel the order. How do you remove and replace the plunger then if you cant just pull it out?

The points plunger comes out from the inside. You need to remove the cam shaft to get it out. If you replace both the plunger and the guide bushing, it can be done by breaking off the old plunger and using a self tapping screw and washers to draw the bushing out of the block. Then use the old bushing to drive the new bushing and plunger into the block.
