Re: leave blower and vac
I don't mean to over simplify this, but are you using fresh gas? Gas blowers and string trimmers are extremely ticky when it comes to gas. They like it SUPER fresh. Not just fresh from the can, but fresh from the pump! And while the gas and oil mixture should be right, it can be off a little bit and still run. Try draining all of the gas out, and then filling up with fresh mix. This is ALWAYS my first step with string trimmers and blowers, and it fixes the problem 75% of the time. Also make sure your spark plug is clean. If you are not sure, a new plug couldn't hurt. Hope this helps!!

Check for spark.. pull one spark plug out set it on bare metal(away from cyl hole fuel could light from spark) turn vehicle over and look for spark should be a nice lightning bolt looking spark... blue spark is weak spark.. and see if it's getting spark...,, if not,,."try new plugs.,wires,distributor cap&rotor " also first.spray a little starting fluid down the injection system turn it over and see if it fires.if it does then it's a fuel issue prob not electrical... try that.hope it helps
Try a spray of starting fluid into the carb. If it fires you know you have good spark. If it did not fire replace your spark plug. If it still won't fire point and condensor need to be replaced. If it did fire spray the starting fluid in the carb a few more times to pull the old fuel through the fuel line til the new gas gets through the carb and then it should run. Some machines have a fuel shut off valve make sure it is open.
check and make sure its getting fuel. when trying to start, spray some engine starting fluid in spark plug hole. just a little bit. replace the plug then try to start it. if it starts then quits then its a fuel problem. fuel not reaching engine. good-day !
Fuel starvation - 'lean fuel' condition
Basic things to check: 1) spark plug 2) spark arrestor in muffler 3) fuel lines and tank filter 4) turn adjustment needles out (counterclockwise) 1/4 to 1/2 turn Chain Saws: 5) check impulse tube and intake boot for cracks or leaks
*if all of the above are OK and/or do not improve performance then: Remove Carburetor 6) replace gaskets/diaphragms a) use a spray carb cleaner to clean jets, holes, and body of carb b) fuel pump diaphragm goes against the carb body, then the gasket towards the outside c) metering gasket goes against the carb body, and the diaphragm goes towards the outside
Main cause of small gasoline engine failure is carburetor clogged. Try spraying carburetor cleaner into carburetor and intake. Check if unit has air cleaner. If engine starts briefly with cleaner then carburetor needs manual cleaning. Carburetor removal and overhaul.
Lots of the starting problems with 2 cycle engines (weed eaters,
blowers, chain saws, etc) are caused by leaving them stored for long
periods of time with the oil/gas mixture left in them. what happens is
that a residue forms on parts in the carb.
Try the following: empty the fresh gas out of the blower. add a gas
stabilizer to the existing gas you plan to put in the blower. You can
get this stabilizer at any auto parts store. While you are there get a
can of spray start fluid. Put the fresh, modified gas in the blower.
Take the spark out and spray some starter fluid in the plug
hole.Replace the spark plug and try to start the engine.It will
probably take a few cycles of doing this to get the blower to stay
when you put the blower up for a long period, empty the remaining gas
out then start the engine and run it till it stops. this gets the
remaining gas out of the carb.
