SOURCE: I have a Craftsman Blower/Vac model 358.794770

Most likely low compression caused by stuck piston rings or a scored piston and cylinder. This unit was made by Poulan and they have had an epidemic of this problem. The solution is to tear the unit down and put in new piston rings. Before you install the new rings you need to get a sheet of glass and some 600 grit wet dry sand paper. Sand each ring down about .002 to .003 and reinstall. This should solve your problem as long as you have good fire and the piston and cylinder is not scored.

SOURCE: Starter rope pulley will not pull the rope back

Most commonly, the recoil rope rewind spring is broken. However, inspect the recoil housing assembly first to make sure no debris or rope fragments have prevented the rope rotor from rewinding. Always remove the spring 'AS A LAST RESORT'. Many rewind problems can be solved by inspection of the rotor and not have to remove the spring. In case you do, I will include instructions on how to re-install.

1) remove the recoil housing
**NOTE: normally you DO NOT need to remove the rotor pulley or spring to replace the rope. This is the area that causes so many guys a lot of extra trouble

2) locate the string that is left and the hole it is threaded thru

3) determine how much string has broken off of the rope that came out

Note: if more than 1 inch is left, then the rope needs to be replaced

4) after rope is obtained, make sure both ends are melted to a point for easier threading thru handle and rope rotor

5) install the rope (with the handle installed on one end) thru the recoil housing and towards the rope rotor.

6) with the rotor free of tension, route the rope from the groove toward center and up thru the hole. Tie a knot in the end of the rope, leaving a 3/8" tail free.

7) wind the rotor in the direction of what the rope would pull (this will tighten the spring) until the spring is completely wound. remove 1/2 to 1 revolution, and then allow rope to wind onto the rotor until all rope is wound.

8) Pull the rope several times to position rope properly into rotor.
*note : there should be NO droop in the handle after released
If droop is evident, wind the rotor and rope 1 revolution tighter so there is no droop of handle when released

9) when unit is functioning proplerly, re-install housing onto unit

SOURCE: My leaf blower doesn't start.

The HT coil may be bad or disconnected. Please check. Unless it converts the low voltage to high voltage there would be no spark.

New spark plug, cleaned air filter, won't start, used starting fluid, how do I check spark?


unscrew spark plug . plug cap back on and hold it against engine and pull cord. plug should give healthy blue spark. if orange the little elbow contact on bottom of plug should be adjusted by tapping it lightly to close the gap between electrodes. do not hold plug by its body when pulling starter rope or ignition. if u can smell petrol on plug then ur engine is flooded.

Electric start on craftsman 9 hp snow thrower won't start engine it sound like it's turning but engine won't start. I can start engine with the pull rope. Started last week with the electric start.


Sounds like you need to replace the gear drive on the starter. If the starter turns but the engine is not turning you have starter problems.

Blower wont start, spark plug dry. appears not to be getting gas


Did you try checking for spark by putting a screwdriver in the spark plug wire socket and holding it close to the end of the plug, while someone pulls the starter rope?

Spark Plug

Every chainsaw relies on a spark plug to ignite the air-fuel mixture for proper combustion. Over time the electrode on the spark plug will burn away and the engine does not start. If the engine does not start, remove and inspect the spark plug. If there is any doubt that the plug is working properly replace it.

Carburetor

If the chainsaw won't start, the carburetor might be clogged or have bad fuel in the float bowl. If old fuel was left in the chainsaw for a long time some of the volatile ingredients may have evaporated, leaving a thicker, stickier product that is more like varnish or shellac. This sticky fuel can clog up the small jets and ports in the carburetor and it can be difficult to burn making it hard to start the engine. The only solution is to drain the old fuel from the float bowl and thoroughly clean the carburetor with carburetor cleaner. If that isn't effective, replace the entire carburetor.

On - Off Switch

Chainsaws are equipped with an on/off switch. If the chainsaw does not start, this switch might be defective. Check the switch for continuity. In the on position the switch should have continuity.

Safety Switch

If the chainsaw does no start, the safety switch - or throttle control switch - might be defective. If the switch isn't engaging with the throttle it won't provide enough fuel to the engine and the engine does not start.

Ignition Coil

If the chainsaw engine does not start the spark plug may not be getting voltage. Power to the spark plug is provided by the ignition coil. The ignition coil is mounted next to the flywheel. As the flywheel spins an electrical current is induced by the ignition coil. If the ignition coil is defective it will need to be replaced, it is not serviceable.

Rewind Spring

The recoil starter assembly has a rewind spring which spins the pulley backward to rewind the starter rope. If the rewind assembly is broken the rope will not rewind and the engine does not start.

Recoil Starter

If pulling the recoil starter assembly handle doesn't engage with the engine and the engine does not start. Repair or replace the recoil starter assembly.

Recoil Starter Pulley

The recoil starter pulley winds up the starter rope when not in use. If the recoil starter pulley is broken or stuck it may not rewind the rope and the engine does not start.

Starter rope grabs at times. why?


try using the de-compression button when starting, will do the same as removing the spark plug but without removing the spark plug.

Failing that, remove the starter cover and check starter cord for daage or signs of snagging.

Toro Electric Start Problem


Remove spark plug and observe condition. Fouled with oil, bad motor. With plug removed pull rope several times to blow out cylinder. Spray WD40 in spark plug hole, pull rope several times see if oil blows out. Spray a lot of starter fluid in spark plug hole, replace plug. Spray starter fluid in air cleaner area of carb, try to start. Replace spark plug, try to start. Ensure oil is full, all mowers have a low oil sensor now. 30w oil. Always use Stabile in gas.

if it wont start, check for spark.how you do that,ok take the spark plug wire out put it close to the sparkplug(use some gloves or something to insulate your self from get electric shot from the spark) find some one who pull the start rope, if you dont see any spark between wire and spark plug, tehre its not spark ,it will never start.you will have to remove the start recoil on the botton is like a damper whitch will have to be remove also ,on botton of it its like a coil whitch with the rotation of the damper when you pull the starter rope provoke the spark and send it to spark plug along with the gas combution get the engine started.that coil some time goes bad and have to be change.if you have electric starter. check the starter also.good luck

NO SPARK, HAVE NEW PLUG BUT IT CONTINUES TO FLOOD.WHEN I TRY TO PULL START, THE PLUG JUST GET WET, PROBABLY IN THE FUEL AIR MIX ADJUSTMENT. HOW DO I CORRECT THIS? FUEL ALSO COMES FROM EXHAUST.


If raw fuel comes out of the muffler then you have an extreme flooding condition. There are no Model Numbers to tell me which type of saw we are working on but this works most of the time.

Try this: Remove the spark plug and BE CERTAIN the stop-switch is in the OFF position. Take the saw outside and bring a fire extinguisher with you! Hold the saw by the rear handle and let the muffler hang down to the lowest point possible. SLOWLY begin to pull the starter rope and observe the fuel being pumped out of the muffler. Gradually increase the speed of the rope pull and get as much fuel out as possible. When satisfied that it's dry, it isnt. Use compressed air to LIGHTLY blow into the spark plug hole and continue to pull the rope. (Might need 50 or more pulls!) Blow the spark plug dry and reinstall it.
Turn the switch ON, leave the choke OFF, and hold the trigger wide open. Start the saw and allow it to run at full throttle until it clears out all unburnt fuel and has good throttle response. If you need further assistance reply to this post with the make and model of the saw and I will be happy to help.

Hope this is helpful,
Dolf-

No spark to plugs affter long storage. Don't have


There will not be any spark to the plugs unless the engine is running, or you are manually pulling on the rope.

Go to any auto parts store and get a can of starter fluid, a new spark plug and a new air filter. Pour out the old fuel and mix up a new batch. While at the store also get a small bottle of homelite 2 cycle oil to mix with the gasoline.

Install the new plug and pour in the new fuel mix. Leave the air filter off and squirt some starter fluid into the air intake as you pull the starter rope. It helps to have this be a two person job.
