Q:

sears craftsman leaf blower won't start

A:

It is very important that your leaf blower powers on properly since your porch can get a lot of dirt and leafs buildup this time of year. While you are waiting for an expert answer, I did manage to find a link that will provide you with a more information about your problem. I hope my link is useful.

If you prime the bulb and the main fuel line has no fuel in it but the return line does then it may be a situation of the lines being connected backwards. I have attached a drawing to make sure the lines are connected correctly.

The primer bulb sits in the "return" line. It pulls fuel from the tank up through the carburetor to the bulb, then back to the tank. So if you have fuel in the return line but not in the main line (the tank to carb line) then it would have to be connected backwards.

Look at the diagram I attached and if yours is connected correctly then I would say there is some kind of a restriction (likely in the carburetor) preventing fuel from being drawn and the vacuum created from you priming is why there is fuel in the return line.

The fuel filter should just sit in the tank; there is no special placement for it or anything.

Thank you for using Manage My Life!

Wade, Thanks for the quick reply. I looked at your diagram and believe it to be hooked up correctly. When looked from the top, the "return" line would be the upper port on the carburetor and the "main" line would be the lower port, correct? That is how it was connected before. The lines are a slightly different diameter as well so I believe it would be hard to mess up. Assuming that is correct, and being that I have a brand new carburetor as of last night - do you have any other ideas? Thanks.

A:

I cannot find a schematic for the carburetor. I do know that on most models, the smaller diameter line should go from filter to carburetor and the thicker line is the "return" line. If everything is connected correctly and you have a new carburetor the only other thing I can think of that might would cause this would be if the line is pinched somewhere. With this being a new carb and lines you may need to prime the bulb 10-20 times to work the fuel up through everything. You didnt mention (so I assume it didnt happen) if you press the bulb and it stays down. That would point to a blockage in the lines for sure.

A:

I did prime it quite a few times (probably 20 total). I forgot to mention, when I installed the carburetor I blew out the main fuel line to make sure it didn't have a blockage. I also held my thumb on the end of it and blew to make sure it held pressure - which it did. If I understand you correctly, when I push the primer bulb, that should pull fuel through the filter into the main line, then back out through the "return" line? That is not what's happening.. I did not replace the lines, but maybe I have a very small crack or pinch somewhere I can't see... Thanks!

You do understand me correctly about how the fuel should come from tank back to tank. Double check the lines for cracks or kinks. As a last resort, swap the lines on the carb and see if anything changes (I dont think it will) , if you havent done that already.

A:

I was wrong earlier. I took a closer look and it does in fact pull fuel through the filter and "main" line into the carburetor when I prime the bulb. I believe this system to be working properly. I'm starting to wonder if the problem is due to lack of spark or intermittent spark. I ruled this out because when I poured a teaspoon of fuel directly into the spark plug opening, it started for a couple seconds before sputtering and dying. If I had an inadequate spark, it may have still ignited this very rich mixture - but not enough to ignite normally? I know my dad replaced the spark plug recently before handing down to me. I am unsure if it is gapped correctly. Does this sound like a potential cause? Any other ideas to troubleshot? Thanks!

A:

In general, if it started when you put fuel in the head, it has spark and should start and run. The spark arrest screen in the muffler could be stopped up causing problems. There could be an air leak causing problems.

I have a similar problem. I am not getting any fuel to the carb. I have new lines and bulb installed properly. I took the carb off the cylynder and when I prime it with the throttle open I cannot feel or see any fuel.

It appears that the fuel is going back into the tank through the return line.

I cannot seem to find the model # on the unit - the number I listed was on a work order from years ago (it is about 10 years old!) when I had it repaired. Where should I look for the model #? The unit I have is a blower-mulcher Craftsman 2-cycle gas unit.

Q:

muffler removal 358797180 Craftsman Gas blower

A:

Thanks for the inquiry and for being a valued member.

I am sorry to hear of the issue you’re having getting the blower started. I know how frustrating that is to have happen.

If you cannot remove the muffler screws through the hole, you have to disassemble the unit. To do this, you have to remove the air filter first. Then remove the carburetor. Once it is removed, you should see a few screws where the carburetor was mounted. You have to remove these screws. Then be sure the screws around the housing are removed. If they are, try to pull the rear housing off the engine. Once it is removed, you can replace the muffler.

Be sure to check all of the gaskets before reassembling the unit. If any of them are torn, they should be replaced.

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