Ok a flywheel key should fit in there nice and snug. Always use Briggs keys never a homemade steel key....

Dat's a NO NO on using gasket sealer on any carb.. Dat stuff comes loose and makes your engine run bad.....That might your problem all along....

It doesn't matter if you just smeared a thin layer or a thick layer on there... If a gasket alone won't seal the 2 mating surfaces then something is warped and not right.....

Yes I no it's not good but I did it to prove the point. Exactly same symptoms were there (well) before and after I used the sealer so in this case it had no effect either way.

Here's some photos of both heads....

I see intake valve not sealing. I see out of round valve guides.
You need to lap your valves and replace the valve guides.

Yes I see a valve lapping that has been over due......... But I don't see a out of round valve guide..... Maybe my eyes are going bad LOL.....

The intake seals should be replaced when you get the kit in ....... That engine was running rich for quite sometime .....

Those carbs are very finicky like I told you before....

Well I'm not gonna edit my last post......

I blew up the pics to 300 percent and I see a lot of SCHITT going on in them heads.... All the valve seats are very dirty...

They are on the verge of going out almost...... Woweeeeeee..... Maybe it's the blow up of the pics but they look bad....

Sorry I didn't reply earlier, I was at the radio station doing my Thursday night show with Todd and we had some great Gumbo in the kitchen cooking and some great friends over there.... Cajun Music at it's best on KBON 101.1 FM plus a variety of country and oldie Swamp Pop music....

Please tell me which photo and where you guys see the intake valve not sealing? .... Seats have definitely not moved.

Yes they will be. Engine was running rich with old carb and still is with the new one too??

Corbon looks bad in photo but is quite thin and most of it is wiping out with a rag. Cleaning and Lapping will commence soon.


Also I remove the flywheel and took out the Key.
The key fits really snug in both keyways (Flywheel and Shaft). I have taken some magnified photos of the Key which make it look really bad but most of those marks are just stains. I even put the Key in a vice to compress test for fractures but it was fine .... Does this look like a B&S Key? ... I've never replaced one so I wouldn't know. It's wider width is the keyway width.... so quite shallow between the two keyways.


All the best.

Yea that's a tell tale for something alright...... The seats are in good shape but need a good lapping with course and fine compound....

That key looks like a Briggs key, but I would put a new one in when you put all back together.... Yours is buggered up a lil bit.....

What do the valves look like >>> Pics ????

This valve guide is oval.

Thats the rubber on the intake seal...... It straightens out when the push rod goes in....
