1PZUK4-14H Carburetor Kit Replacement for Mountfield RS100 Engine HP164 HP414 SP164 SP414 Lawnmower Engine Parts with 2pcs Mounting Gasket and 1pcs Fuel Filter

Arrived quickly and fitted perfectly to my RS100 lawnmower engine.Works great

Gaskets were not quite the same on my Mountfield SP414 but made do. Was not expecting much but the thing fired on a partial pull. It has never started so easily, nor has it run so smooth. Can recommend! 5 min fit with a 10mm socket.

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.

The carburettor arrived on time and looks identical to the old one on my Mountfield RS100, BUT please be aware that the gaskets supplied are useless only ONE out of the 3 supplied fitted this carb. When I obtained a new gasket set and fitted the carb it run very smoothly

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.
