Question about Briggs & Stratton Lawn-Boy Insight Series 21-Inch 190cc 650 Series Gas Powered Engine Variable Speed Self-Propelled Lawn Mower
Sounds like you will need to clean your carburetor.
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 a few times, 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.
If the mower/weedeater is over a couple years old, then I also 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.
When you clean your carburetor and remove the jet screws, You will first seat the jet screws and count the number of turns it takes to seat the jets from their original position.
That way when you go to put the jets back in, you know how many turns they were in/out.
