Lawn boy snow thrower 320e won't start. Need help fixing it.

Resolved Question:

I have a lawn boy snow thrower model (320e) model #  2 8 2 2 2 7 9 0 4....... =serial number. It wont start and i know why. I failed to drain it last year . Each time I do this I bring it in and service clean out engine or carburetor. I did not have time to do this and we expect a major snow storm tomorrow. Can someone walk me through fixing this at home? Are there any online instructions about what to do?

Hello,

I think I can help you. I think you are right about the carburetor job, but first

lets do a quick test that will tell us if you have fire(ignition to your plug) and compression. Take the air filter cover and air filter off of your engine. Now, we are going to prime the engine with some gasoline, or spray carburetor cleaner. Squirt a small amount of carburetor cleaner, or a small amount of FRESH gasoline into the throat of the carburetor. Now try to start it. If it starts up with the priming you just did, you know you've got compression and fire. If it dies shortly after you've primed it, you'll know you have a fuel and or carburetor issue. Try that and let me know what you find and we'll go from there.

Thanks,

Kyle

reference numbers 250, 245, and 245B, will have to come off and that will expose the throat of your carburetor(#380) so that you can squirt your carburetor cleaner or gasoline for the test. Let me know what else you need if anything.

This looks very complicatred . I need to know where to start . How do I access the above areas . I need to know where the "hood" is to look under . Do you have a diagram of the model , which you can say" go to screw such and such , then lift off panel, then find carburetor" etc? Can you tell me what kind of tools I will need? does 250, 245, 245b have names? are they the air filter and airfilter cover? You call this a "quick test" but it looks like you have to take many parts off to get to 250, 245, 245b. Please advise

Here's a diagram of the shrouds that will need to come off of your snow thrower to expose your engine so you can do this test.

If you look at ref # 4 and ref# ***** in the diagram, you'll see that 4 is a fuel cap and 19 is a muffler guard. They both are attached to the main shroud. Ref # 37 is the main shroud that will need to come off to get at your engine. The diagram shows all the screws and bolts that will need to come out to get that part off.

Once you get that shroud off if you look at the previous diagram I sent of the engine, 250 is the air filter cover, 245 is the air filter, and 245 b is a pre-filter. All of those parts will need to come off before you can do the prime test. Once you get it torn down to the carburetor and try the priming test, let me know what happens, and I can walk you through the carburetor cleaning once you get there.
