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!!

    Also, try to use high octane 100% gas. Ethanol will eat up rubber O-rings, etc. . . over a period of time. You should see an immediate difference in how it runs. Try to drain the gas out of the tank if not used for more than a week, as it will tend to gum up the carb from sitting, especially if left in the heat.

Why won't it start?


Use carburetor spray from now on, starter fluid does damage.

This may need an adjustment on the carb.

If you pull too manyoung times, it could be flooded.

Wait a little, now remove the exhaust, spray carb cleaner into the exhaust port and plug hole... give 2 slow pulls, just enough to make the cyclinder go up and down a few times, then give a normal pull...

Now if it starts and runs a few seconds, an adjustment is needed on the carb.

Hello i have husqvarna 150bt 1st problem was the pull start wasn't working removed and was able to rotate shaft with ratchet so i lube it with wd-40 and now fine 2nd problem wont start. removed carb....


Spray some starting fluid into the open throttle and see if it instantly fires. If so, it is fuel or lines, filter, quality, quantity. Water in the fuel, many other factors can play a part. If it won't start with fluid, then the ignition is your weak link. If it is a champion plug, toss it. A wet plug won't fire either, even with gas.
More than likely, it is fuel delivery... still starting fluid is #1 tool.

Im a small engine tech im working on a echo pb251 it has spark and getting fuel but will not start, even sprayed carb cleaner in cylinder and it will not fire any ideas


have you checked the muffler and ex port for carbon / blockage?


have you checked the timming key ?

does the unit have enough compression ? by enough i mean 100 psi or above is considered
the btm limit

does the machine fire on 2 stroke mix , if you pour some in plug hole ?

will it fire again if you spray into carb throat with the carb on ?

is the spark still there while under compression pressure ( test using spark tester ) connect between h t lead and spark plug, you should see it spark and jump a 6.00 mm gap to pass a spark load test

if the unit does not fire with mix in plug hole suspect compression ?

if the unit does not fire with mix sprayed into carb throat - suspect a induction problem

ie a air leak either around carb, manifold , or intake boot ( if it has one ), base gasket , crank seals or impluse hose or cracked insulator if it has one

either way i think you will need to pressure & vacuum test crankcases for leaks

you will need to block off intake and ex and put in a air adapter inthe plug hole to connect a pressure or vacuum tester

place piston @ bdc and pressurize to 7 -8 psi check around areas as above of leaks with soapy water , you will see bubbles where a leak is , but the pressure remains constant for at least 2 minutes thats good , the use a vaccuum tester and apply 20 - 30 inches vaccuum to c/cases
vaccuum should hold if not use crc or soapy water to find where uit is

a 2 stroke will exhibit symptoms such as ,revs out far too much ( lean ) overspeed -
very hard to start, or no start , run hot , have low power , stall if trying to idle or seem to raise their idle speed up and down , cannot get reliable hi / lo adjustments set on carb

2 strokes need air tight cases to create vacuum and pressure pulses to pump mixture to cylinder and to operate the carb fuel pump diaphrams


remember this F A C T S

F = Fuel

A = Air

C = Compression

T = Timming

S = Spark

CRAFTMAN LEAF BLOWER WONT START


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

Hi gr2954;

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 running.
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.
