Yes a thought that was right. Going to try that later on after the footy. I won a 27cc engine with a walbro wt997 on eBay last night for £40 so going to put that on the marder when it arrives. Hopefully I don’t have any issues with that!!!

So am I right in saying the yellow fuel pipe with the little filter on inside the fuel tank goes to the bottom and the black return pipe goes to the top of the carb?

Pipes are on correctly. Foam fg filter is now installed. It did have a k&n style filter on it originally. I haven’t tried s different carb yet

Also the mixture is 25/1

i Have tried everything with the h&l needles and can’t seem to sort it. I may just get a new engine altogether.

Yes a new filter has been fitted. Fuel and oil is new also. It runs fine on idle but any revs it just starts to bog

Hi I have an fg marder with a 23cc engine in it. Since I got it second hand the engine Boggs down when you put any acceleration on it. If I slowly build the speed up with the back wheels lifted off the floor then it is fine. Have tried putting carb back to manufacture settings and tweaking here and there but still no joy. Any advice is appreciated. Thanks

It's a 23cc zenoh or something haha. Is it easy?

Yeah I will mate and no ill have to buy one. I've tried tuning it but still no joy. When I start it from cold how long should I leave it to warm up? I might end up just getting a new engine for it save all the mess haha. That's if I can find a cheap one anywhere

It's got a k&n style air filter on it. Was on it when I got it. Tried taking this off though and it still bogs down when I get to half throttle

Checked it and its all clear. I'm using 25/1 and just normal 2stroke I got from petrol station.

Nice???? looks awesome

Yeah there's a little walbro fliter in the fuel tank connected onto one of the fuel lines and that seems okay as I've removed it and blew through it. Lines are all okay. There is a little connector on one of the clear fuel line where it looks like it's been chopped and reconected at some point. Could this cause anything?

Right guys I've cleaned the carb out again and it's still the same any advice would be helpful thanks

Fully open the throttle*
