What is your exhaust valve clearance?

 

[Fish]

And how are you "reading" them?

This is posted for Boudreaux In Eunice La. (as requested);

He'll chime in re setting the governor:

Mkala you see that tang inside the circle ???? That is your main governor adjustment........ Bending it up will decrease your RPM's......

That adjustment knob is more or less a fine tuner .................

Ok just like the instructions in the manual says.........

Step 1 release spring tension on nut..... ETC ETC.............

By bending the tang you are getting the RPM's close to what you need then you fine tune it to your RPM and Hertz / Cycles with the speed adjusting nut..............
I hope this kind of clears it up a little bit for you.......

The diagram is on post #17 I think ~!~!

Scott, the muffler looks almost straight... and there is a plate between it and the block (the plate the come in front to lock bolts with bending tabs).
But on the part chart the gasket between the plate and the block is missing. And there is some remnants on this plate, exactly.

For the carburetor double gasket, looks like they a factory but I find that strange too ! again carburetors mounting screws looks new. I'll try to replace with only one...


Boudreaux In Eunice La ha yes it's for the cubic inches ! Nice explanation thanks ! I did not think at this at all, cubic inches does not speak to me... don't have the habit of this unit. For me it's a 206cc, but its a 12.6cu in too This has probably something to do in the model serie naming : 130000

Thanks for the information for setting the governor too ! Yes I see this tang, ok I understood. It's probably while I turned the thumb nut it was only making small changes !
The last mystery thing is this tang has no mark on it, so never modified I think. But while releasing spring tension with bending it I can lower RPM. Yes I checked the posted diagram and have stored the L-Head manual, it's quite handy

Merci mon ami !


Fish, I posted clearances a few post ago, but here what I measured :
Exhaust between 0.10 and 0.15mm (can put 0.10mm feeler gauge but not the 0.15)
Intake almost 0.15mm (gauge is tight, should be more free)

So I have to increase EX to 0.25, and do a small touch on intake. From what I know EX is more prone to "move", so it make sense ?
By the way I use two feeler gauge sets, one good but with low resolution (0.10mm) and one cheap with more feelers, and they both match. Of course I check that with piston at TDC, on compression stroke.

Mkala .......... The tang shouldn't have marks on them if it was done right..... Post 17 in the bottom diagram you can see the tang bending tool on the tang....... Briggs sells those tools..... I had one years ago..... I just use my Snap on needle nose pliers to adjust the tangs now......

Yes the 13 cu. inch has to do with the Model Number...... All Briggs engines do that..... Vanguard 366776 = 36 cu. inch 18 HP........

Plus tard ........

Ok, yes I see the right tool with the fork style to bend the tang... but when I see the crankcases bolts I think the guy was working on before me was in hurry or not that careful ! :thumbdown: So perhaps it had the tool... probably not

Interesting, never think with the cubic inches. I saw the size increase with number, but now as a more clear signification ! It's nice to learn things thank for sharing ! :smile:

A plus mon ami

If you want to........ Try this radio station to listen to ...... It's Cajun French music, Swamp Pop and well a good variety of music.....

KBON.com On their website hit Listen Live ......... It's a radio station not far from me here in town.... I do a Thursday night show with Todd Ortego from 6 P.M. till 10 P.M. We have a blast on that show......

Scott, the muffler looks almost straight... GOOD and there is a plate between it and the block (the plate the come in front to lock bolts with bending tabs).
But on the part chart the gasket between the plate and the block is missing. And there is some remnants on this plate, exactly. OK, GOOD, GUESS IT BLEW OUT OVER TIME..

For the carburetor double gasket, looks like they a factory but I find that strange too ! again carburetors mounting screws looks new. I'll try to replace with only one...

Boudreaux or another member should know about the intake gasket. Maybe it's designed that way?

Someone will respond and know for certain...

 

[Mkala]

Boudreaux, I'll check, but with 7 hours difference will be difficult to listen I think

Scott, perhaps found an explanation on a part site : that for another gasket, but they say stacking two is better to insulate the carb from block heat. Make sense, as all is aluminum heat conductivity is good.
I just orderd the compressor tool for valve springs and the muffler gasket.

Now I wonder if I have to lap the valve. I don't wont to order the good briggs part, to expensive for my occasional use, I'm not a pro.
But I can find plastic or wood handle lapper for cheap. About the compound I dont know what I need ? Found these two available on ebay, any thougts about them ?

Mkala ........... Get both coarse and fine lap compound.......... I hardly use the coarse...... yes you can find the lapping tools cheaper at local parts stores or NAPA stores..........

The one I have is a double ender and the small end is 1/2 inch..... Perfect for the newer small valves that are concaved...

The Briggs lapper is 5/8 inch and doesn't fit on the small valves well........

KBON is a 24 hour station but only has live Dee Jays from 6 AM till 10 PM at night .............. Saturday and Sunday mornings are mostly french music............
