As  you push the button gas it pushed through and the amount is not your control.  Although if you break down and "READ THE DIRECTIONS", it might tell you to set throttle,  push twice and pull on rope or however.  If you don't have manual for  directions then google and find your brand.  Last but not least check, clean or replace the spark plug.  My point is with things like this you usually have to do a certain amount of prep.  If all fails take it to a repair shop.

There is an awesome amount of insecticide.  I find the granules spread everywhere helps to reduce the millions to a livable amount.  Down side is you have to repeat 1 to 3 times a year.  Depends on where you live and climate.  I love the Weed & Feed for the lawn.  It gets rid of the weeds beautifully & perks up grass to grow where weeds were.   But you have to repeat same as insecticide.  I added this because a healthy lawn helps get rid of varmints.  Same deal with ant killer spread over every inch of lawn not just the hills.  The varmints has no problem setting up house 4 feet from your poison spot.  You don't have to spend big bucks for these items when you cover all of lawn plus lots of times if  you buy large bags it is cheaper.

When we solve this puzzle I have another picture for you all to ID.

That is a good guess dowsa.  I will revisit the Tits.  They do come in different colors.  I just don't know.  I found this picture on Pinterest.  I liked it and pinned it then several people asked what kind they are and I am clueless.  I tried to look them up and I don't think they are American.  I spent hours combing through bird pictures and the closest I came in coloring was the hummingbirds.  I have never seen a hummingbird flock and it looks too big.  So I have put the question out there, "What kind of birds are they and where do they live?"  Thanks to the replies now help come up with an answer.
