Posting for a friend. When rebuilding the carburetor should the new needle be staked lightly into the seat? If so, will just a couple light taps be sufficient?

I heard of others doing this, but it just don't seem right in my mind.
If it's not seating right...something's wrong.

Purdy Swoft · 01-24-2018, 02:42 PM

I only do one light tap .

I use a small brass cobbler’s hammer and give it two taps.

I use a two-ball type float valve. These are similar to the original Grose-Jet Valves available up through the 80's or so. Grose-Jet valves were the best float valves available for any application. Today's suppliers sell the modern equivalent of the same valve.

No staking, no ethanol to worry about, no leaks...not ever.

I lapped the needle with toothpaste, then gave it a light tap with the pliers. Never leaked again.

The valve mentioned here and sold by Berts has a Viton tip on the needle unlike the Grose Jet.

Hitting the needle with a hammer might damage or split the soft Viton tip.

I have used a number of these and have not found a need to
"Stake" them.

Right, and I wouldn't attempt to lap this type either.
I only use original all metal needles and seats.

I go for steak. Well done.

Thanks again guys. I let him know what the general consciences was and he said he gave it a couple light taps after installing the needle and all is good, no leaks.

Coming in late on this topic. I usualy stake conventional type valves with a couple of light taps, I don't do anything with the ball type (like the grosse jet)and neither do I do anything with Viton tipped ones.
Problems I have encountered with brand new ones 1)... conventional ones can sometimes leak- try flushing out with fuel or air as sometimes some swarf present 2 ) Ball type ones ( especially the modern versions that are being sold) can some times leak 3) Viton tipped ones can sometimes stick closed... hopefully vibration of engine will unstick them in working environment ... My advice is to check them all when fitting them ( and I really think the manufacturers should be doing this!)

I'm pretty sure the Viton part is the gasket, not the tip. This is a two-ball type valve, not a needle with a tip. Although the description on the Bert's site is a bit confusing, I hope Steve can clarify.

The only reason for staking a brass needle into a brass seat is to make sure the two parts fit together properly. If the seat is a little too big, staking will push the needle further into that seat and align the two. If the seat is a little bit too small, staking will spread that seat so they fit perfectly.

I know that anything other than all brass needles and seats are never supposed to be staked. However, I’ve learned that staking brass set-ups is maybe not neccessary, but why take a chance. Just stake them and be done with it. It’s one less thing you have to worry about later on.

Stake those suckers,

Mike
