Briggs 5HP IC Generator

[Fish]

I seldom lap the valves, it destroys the good seal made by properly cutting the valves has made. I will do just a light touch, to see that the seal is good.

Thanks for information !

Permatex did not give grit... from some review they say it's quite coarse. I don't have local shop to buy this kind of thing so I have to look online (not in habit here to have auto shop unfortunately ).
Which grit should I use about you think ?

Exactly, I will just check if this make a nice little circle all around. Don't plan to do a big / aggressive lapping - just want to be sure all is seating properly why I'm in.

See you :smile:

A real "light" grit would be TOOTH PASTE...

Use the stuff with a good mouth wash in it and your generator's exhaust will smell so sweet..............

This is a good idea Scott ! I'll try as soon as I got tools (valve spring compressor & lapping tool)

Ronno6 I prefer burned gasoline smell :tongue: (for the engine exhaust :laughing: )

Neway is the way to go!!

Here is what you need.

The abrasive in tooth paste is calcium carbonate which is way softer than both the valves & seats.
Fine for paint and brass or alumium parts but all it will do on a valve seat is fill the voids so it looks better.
OTOH getting it into the bore will remove glazing.
Calcium carbonate was the abrasive in Bon-Ami & an old bodge was to toss some into a glazed bore if the rings did not seat.
Tooth paste is around .05 to 1 micron and way too fine for lapping valves.
Brasso might work but that is 4-8 microns which is again too fine for lapping.

A sort of comparrision would be trying to remove deep rust with 2000 grade wet & dry.
You can do it but it will take a very long time.

Mkala ............... Clover makes the lapping compound for Briggs..... It'a double sided container.... Course on the top and fine on the bottom .... Or the other way around LOL.....

Look clover up and see what you find Mon Ami ~!~!

Plus tard ..............

Thanks Fish, but until I find very bad seats I dont plan to re-cut them.

bertsmobile1 It will just be for checking if I'm not sure they are seating correctly ... if I need to grind them for sure I have to buy the right thin as Boudreaux In Eunice La. suggested : Loctite clover. But I wait the valve removal, for now I see Loctite Clover Fin& Corse (280 & 120 Grit) @ 20$ + 20$ ship on eBay.
