Check your fuel filter in the fuel tank,if you have one.
If the mower/weedeater is over a year old, then I recommend that you buy
and install a new carburetor repair kit,because the diaphragm will get hard
and that will cause it to be hard to crank.
Sounds like you will need to clean the carburetor or replace your carburetor
internal rubber parts like the diaphgram and O rings.
Be sure to use compressed air to blow out all the fuel and air passages.
Be careful when blowing out the passages, because there are sometimes small
rubber type seats in the bottom of some of the passages.
Sometimes you can get by with priming the carburetor or using starting fluid
and letting it run a few times like that and it will flush the gunk out of
the jets,but most of the time you will need to rebuild the carburetor.
Keep in mind that the float for the carburetor must be level when you go to
reassemble the carburetor or follow the instructions you get with the
carburetor kit.
When you clean your carburetor and remove the jet screws, you will first need
to lightly seat the jet screws.
But before you lightly seat the jet screws count the number of turns it takes
to seat the jet screws from their original position.
Be sure to mark the turns down on a piece of paper.
That way when you put the jets back in, you know to lightly seat them first
and then turn them back out to their orginal position before you started.

Just fitted a new carb to my gilera runner 50cc and now it revs really high on idle


I would check a few things. First off make sure the throttle cable is adjusted correctly. Second, try opening the throttle half way and letting go you should hear the inside parts of the carb click as they seat. Third, find the idle adjuster screw turn this anti clockwise and see if the idle speed drops down. Fourth check the choke mechanism is working properly choke/cold start forces a rich mixture to the engine and increases the idle revs.
it is worth checking the pilot air screw is adjusted correctly. Hope this helps.

Backfire carb


Urals need to be throughly warmed up before riding, old technology engine. As far as the revving, I'd Check for vacuum leaks at the Carburator with some carb cleaner while idling, and if that's not it, I'd check the choke.

Hi, Anonymous and the usual suspects are:

Need instruction on how to adjust carberator


Adjusting carbs on chainsaws is not to be taken on lightly, there will normally be three screws, an L screw, an H screw, and an idle scre, the L screw will increase the fuel mixture from idle to half throttle ( they are fuel screws not air screws ) the H screw will adjust from half throttle to maximum revs, start with a base setting of between one turn and one and a half turns out, start the saw and warm through, allow it to idle, if need be increase the idle screw to get an idle, turn the L screw in slowley, the revs will increase as the mixture leans off, it will reach a point where it starts to die, now back it off a quarter of a turn, blip the throttle, the saw should pick up clean, if it has a flat spot increase the L screw slightley, now set the idle so it idles without the chain moving on the bar, now screw the H screw in to get full revs, be aware this should be set with an engine rev counter, do not exceed the manufacturersmax revs, hobby saws normally run at about 12500 rpm with an idle speed of 3000 rpm.

5. Broken throttle return spring.
6. Damaged diaphragm or slide.
