Hello guys thanks for your help I agree it does sound carb related I have thorughly cleaned the carb in the most delicate of manners ensuring float is taken the very best of british care.

Irish john I have noticed fuel running down the face of the air filter box like you have mentioned in your post.Although im sure upon doing my sugical clean of the carb i would have released any gunk from the carby.Can you tell me the method in simple terms as to how you cleaned properly the needle and seat...and also where the air to fuel screw adjustment can be found just incase the engine has been tinkered with ....could possibly of been accidently upset along the way.Does seem to be running very very rich from the exchasut emmissions

Kindest of regards Al

OK Atudge here are the pics with notes and also a PDF file. The pics belong to another kind MBc member's who posted this over 2 years ago and it is all self explanatory but I have annotated them for you. It is quite usual not to get the carb totally clean first try but the second go should get it right. If fuel is leaking out the air filter it can only be gunk in the needle seat because I'm sure your float hasn't got a hole in it and if it floats it will do the job and push the needle onto the seat to cut off the fuel. Take care and be very hygeinic and clean about the process. I've found little bits of stuff in my needle/seat that look like seaweed! The PDF is just more instructions courtesy of one of the old timers on MBc.
You can't beat MBc for finding things out can you?
If they read this Forum in China we would be out of business!

Ok so I have given the carb a thorough and delicate clean of all the items listed in the pictures provided..I fired her up and it ran better but then cut out.. bugger!!

So I tried what else you showed me which was the air/fuel and after have small adjustments to that It starts and runs like normal without the choke on or if it needs to be on its only on half as much.It sounds a lot stronger so Im presuming something along the line has upset the air/fuel and its been running very rich hence the fuel out the filter.I think the air/fuel still needs a small amount of tinkering as it still seems a little shakey but on the hole a vast improvement.

I reckon the slightest of turns and it will idle perfect.

Thanks for your help I wouldnt of been able to get this far without it! Cheers Al

I think you are nearly there Atudge. Maybe ask a local mower engine repair shop or motorbike man to adjust it for you if you have problems. He probably won't charge you for it and will show his method of doing it.
Glad to be able to help someone.

You know? I had the same problem with my HS 4-stroke..I was about to tear apart the Carb and if that didn't work..I was gonna call and get an exchange on the engine via Warranty..


Frustrated! I was ready to grab the tool box..I finally took a deep breath and decided to check the fuel switch..Why not since I have checked just about everything else...

Sure enough the Fuel switch was on quarter open on the fuel tank..Runs like a Charm now..

It's always something really really simple isn't it Kadude. Like how HoughMade suggested to Atudge earlier that the first thing to check is a blockage in the fuel supply - usually on the inside of the tank around the little filter or in the on/off hosecock.
