You need to determine if the problem is no spark to the spark plug or no fuel from the carburetor.

I would remove the spark plug. Attach the wire to the plug and hold the spark plug with a pair of insulated pliers or a thick cloth or thick gloves so the base of the plug is touching a clean spot on the engine. Get someone to pull the starter rope and see if the plug arcs from the anode to the base. You need to do this in a darkened area. It is hard to see the arc in bright sunlight. If you have no arc, the ignition module, the engine kill switch, or the wire from the ignition kill switch to the ignition module is bad.

Install the plug with the ignition wire disconnected, prime and choke (if you have a choke) the engine. Pull the starter rope 8-10 times and remove the spark plug. If the bottom of the spark plug is wet with gas, you are getting fuel. If the spark plug is dry, you probably have a fuel line with a hole in it.

If you have more questions, reply on this thread and include the model of the blower. I will be glad to help.

I am getting gas to the carb and the spark plug is wet. I tried to pour a little of the gas oil mix into the sparkplug hole as one person suggested and i got a little bit of a sputter, but it would not start. I didn't try the plug arc yet. I can't touch the engine with the plug : it's wncased in plsstic. Would any touch to a metal surface do?Now if it''s the coil or something inside where the sparkplug gets its spark, how do I take this thing apart? Model 358.794961. Remember I'm an amateur at this.

If the spark plug is getting wet with gas, the problem is probably in the spark. Run a wire from one of the screws that mount the carburetor to the base of the spark plug to test for spark. To access the ignition module go to [Parts Direct | www.partsdirect.com?sid=MMLxexpertxmerch] to follow these instructions. Remove items 35-48 on page 2 of the parts diagram. Remove the screws holding the engine housings (items 20&23) together and remove the housings. This will let you access item 13, the ignition module. The clearance between the flywheel and the ignition module is .010-.012. This is the thickness of a business card. Reply on this thread if you need more help. I am glad to help.

How do I replace the fuel filter and two fuel lines for craftsman leaf blower model # 358797202

I am sending you an image showing how the fuel lines are routed on your trimmer. Make a hook from a clean piece of wire and fish the small line and the fuel pick up out of the gas tank. Disconnect the fuel pickup and pull the fuel line out of the tank through the hole in the side. When you install the new fuel lines, leave about the same amount of slack in the small fuel line as the original had. The large fuel line goes into the fuel tank 1 1/2-2 inches. Cut the end of the new fuel lines at an angle to make them easier to push through the holes in the tank. Pull the fuel lines into the tank with a pair of needle nose pliers. You can see a parts diagram and order parts for your blower at www.searspartsdirect.com.

I have a Craftsman 25cc leaf blower that would not start ! Its on its 5th year of use at home. I was to the point of throwing it away and buying a new leaf blower, but kept working on it and finally found an easy to fix problem. I removed the cover to expose the engine - 3 screws. I found that the 2 screws that holds the engine head on was loose. I tightened them, as both were loose, and it fired up and runs better that it ever has. I also cleaned the carburetor with carb cleaner, it u want to, not hard to do !! Also the inside screw, on the head, is hard to get the screwdriver on so it took my small hand grinder and ground away a small hole, on the blower casing, so the screwdriver seats squarely on the screw. Hope this covers someones problem, as this is something to check before you buy fuel lines, filter, plug, etc.

Q:

Model 358794961 Leaf Blower (seized) is it worth fixing? 358794961 Craftsman Blower/vac

A:

Thanks for using SearsPartsDirect.com, and for being a valued member. 

Sorry to hear of the issue you’ve had with the seized engine on the blower/vac. I know how frustrating issues like these are to have.

Typically, the rule of thumb on whether to replace or repair is 50% of the replacement cost. If the repair is less than 50%, then it’s worth it to fix, if not, then you might as well replace it. Also keep in mind the age of the unit. With it being a 2005 model, it has about 9 years on it, and if you invest money into the repair, will it need any further maintenance or repairs on the short term?

Besides the cylinder and piston kit, you will also want to purchase the gasket kit, part number 530071458. There aren’t any special tools required, but this repair does require disassembling the entire engine. It’s not terribly difficult, but you will need to have some mechanical experience. There are some great YouTube videos you could watch on replacing the cylinder/piston on these smaller engines. I would recommend watching a few to determine if this is a job worth tackling.

I hope this helps, and thanks for using SearsPartsDirect.com. We appreciate your business.

Thanks for the response. I've removed the cylinder jug. The piston ring is what caused it to fail. There is some damage to the cylinder wall that extends less than a 1/4" above the reliefs cut into the cylinder wall opposite the ports. It can be felt with with a fingernail. Is honing possible on this cylinder jug?

I'll go ahead and update this thread and provide the answer to my question, (which I got at a local lawn equipment dealer and repair shop) in case anyone else encounters the same problem and needs to know. The parts counter informed me that NO, they do not hone a damaged cylinder, they replace. I went ahead and ordered a new piston, ring, and cylinder and gasket to make the repair on the engine, which is by the way is made by Poulan, on this Craftsman model. This site was very helpful to me on the last two repairs I've done to my mower but seems a bit light on "Expert" help this time around.
