Is your air filter clean?
Are you sure the fuel line isn't clogged up?

air filter isnt too bad fuel line is clean checked carb to make sure fuel was getting through

this is the same air filter i have can i wash this or do i have to buy a new one?

Looks like a black lump from here.

If it is foam, wash it out with dish soap and warm water. Wring it out in a clean towel. Pour a teaspoon of clean engine oil on it, and wring it in your hands until the oil is evenly distributed.

but will that solve the problem of not idling properly

Not likely, but if it's really stuffed up, it won't help.

90% chance your idle jet or circuit are clogged. Could also have a bad carb gasket or boot, loose carb, or other possibilities.

why would a bad carb gasket cause that problem

 

[Doc Sprocket]

Why would any bad gasket cause any problem? Gaskets keep things in that shouldn't go out, and keep things out that shouldn't go in. In this case, we're talking about air... A bunch of air being drawn in at a carb base gasket (or boot) will throw your air/fuel mix out the window.

Your A/F mix would appear to be of some importance...

il replace the gaskets in the carb could i use that gasket maker sealant because i dont have any gaskets at the moment ,would that work ok its the gasket sealant ?

its gasket sealer ,it makes the gasket can i use this?????

 

[souperman000]

Don't use gasket sealer. Always creates more problems in the future. Get some real gaskets or gasket material and do it right the first time.

You could also use cereal boxes.

ye ino that but i dont have any real gaskets right now and i wont be able to get them for a good while ,how long would the sealer last if i do use it ?

 

[Doc Sprocket]

You could also use cereal boxes.

See above.

would that work if i used cereal box cardboard then instead of using gasket maker ,but the gasket on the carb is a rubber gasket not paper so would that matter

 

[zip kart]

i had a look at the gasket in the carb and it was split at the end so i took off the gasket and used some gasket maker and rubbed abit into the grove and put the old gasket back down on it so it would stick the split ,the old gasket wasnt bad it was just split and i joined it back so hopefully this will work il have to let it set now and put it back together tomoro

 

[zip kart]

also is gasket maker gas prof????
is there anyway i can make a gasket for the carb bowl ,the gasket thats in it is a rubber 1 so could i just make 1 out of cardboard???

 

[Doc Sprocket]

Can you please, please make use of the "EDIT" button and avoid the multiple posts?

I doubt you can make a cardboard bowl gasket accurately enough. Plus, on many carbs, that thickness is pretty critical.

An old inner tube might work
