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.
