fg marder problem

[hensh1990]

Hi guys I'm new to this forum so be nice???? I have a fg marder which will start up but when I open the thrit the fully it bogs down and cuts out. I've tried putting it to factory settings on the carb and what not but still does the same. Any help would be very much appreciated. Thanks in advance

Fully open the throttle*

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

Does sound like fuel starvation at high revs....

 

Check the tank breather and the fuel lines. They get hard and brittle with time, and it's worth replacing them. Watch for any kinks or splits.

It's easy to check for a blocked breather.... just take the fuel cap off and see if the problem goes away. That would restrict fuel flow... and at high revs, it will be most obvious.

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?

It could be mate see if its blocked up.

 

What oil and mix are using in the fuel?

[hensh1990]

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

Your air filter clean mate?

Also not over oiled;)

[hensh1990]

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

[mark35]

Sounds like it needs a good tune up mate if you do get it sorted bin the k&n filter there crap at keepin the crap out lol. Have you got another spark plug you could try? Just throwing ideas out there:D

[hensh1990]

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

[mark35]

You could just rebuild your motor rather than buy a 2nd hand motor you'll be lucky if ya get a goodun mate.

Btw what motor do you have?

[hensh1990]

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