LQ39 Carburetor Rebuild Repair Kit with Float Replaces for Zenith Wisconsin Engine VH4D VHD TJD THD AHH

Gaskets are good, jet fits fine. The needle seat has a different thread pitch ( you can’t thread it in to the carb body) than the original one so you can’t use it. The needle body is larger than the original so you have to modify it to make it work if you are using the original needle seat. For the price it is worth it especially if you need to replace the float

The threads on needle seat were right (24), but too big to thread in…threads were too tall by .020 with mic. Luckily the float was on the money, and that turned out to be my problem

As reported in other reviews, the treads on the float seat are wrong. The other non-threaded parts are functional. It would be better if they did not even include them.

As mentioned in the other review, the thread pitch of the needle valve seat is not compatible with the mentioned models. I've tried thermally expanding the carb body with fire to expand it enough to seat, and that didn't even work. Don't waste your money. This kit isn't compatible with many of the models listed. I don't know where they got the valve seat dimensions, but it wasn't through Zenith.

I bought the kit because the old needle had lost the rubber tip. The seat in the kit has the wrong thread pitch for my carburetor. The new needle wouldn't seal with the old seat. So I ended up buying a $90.00 carb kit from a small engine repair store and it works perfectly. This kit was a waste of money and time for me.
