1PZ UK4-14H Carburetor Kit Replacement for Mountfield RS100 Engine HP164 HP414 SP164 SP414 Lawnmower Engine Parts with 2pcs Mounting Gasket and 1pcs Fuel Filter

Happy with the carb works fine

Hyundai mower now 7 years old.Had a few services. And been servicing myself and cleaning out the carburettor etc. but recently took apart and the needle got bent. Wouldn’t go back together.Found this and hoped for the best… but arrived and was identical in every way. Fitted easily and started perfectly on first pull.Strangely the old carb needed about 3 pumps to start.This needs a good 8 or 9 pumps before pulling the starter cord.And needs a couple of pumps to restart after a pause.Starts first time each time.Great replacement part

This was a replacement carb for a Mountfield mower which was in poor condition. Replaced carb with original hoses as the hose supplied was slightly different outside diameter and clip was loose. Mower started first time and and now runs perfectly.

I should have bought this new carburettor a long time ago! I've cleaned and set up the old carburettor many times to try to get my lawn mower running better, but it never ran well until I fitted this new one. I've had the mower for nine years and it's never run so smoothly as it does now. There is also a very important inline fuel filter included. Recommended.

Hi,Item sold as compatible with Mountfield HP 164 mower. I can confirm that it is not compatible unless there a other versions of the HP 164.

Fits ok but not correct for my Sp414

I repair lawnmowers. Normally a stripdown (main jet and emulsion tube out). Clean with jet files and brake cleaner. All good again. But I got a second hand repair in and I think someone had drilled the main jet. It was running very rich.Included gaskets are fine. I just re-used the originals as nothing wrong with them. Fuel filter unnecessary as the RS100 has a fuel filter inside the fuel line at the wide end that connects to the petrol tank. Check fuel does flow while the fuel line is disconnected from the carburettor. TIP: A plastic food bag clip is ideal to clamp the fuel line off whilst swapping carbs.This carburettor has a brass adjustment screw. Just ignore it. It is to adjust the bypass jet mixture for tick over applications. As the RS100 is a fixed speed and governed engine it is basically redundant.D.

Absolutely identical to the original carb that comes on the RLM4114 four stoke lawnmower which i now believe it obsolete. Comes with all gaskets, new fuel tubing and even an inline fuel filter. Great item and great find!
