Small Engines (Lawn Mowers, etc.): Screaming in Engine, starter clutch, flat screwdriver


Question
I have a 10.5 HP Tecumseh Snowblower motor on my snowblower. Yesterday i When i started, it started fine, but after about 5 mins a loud screaming noise came from the engine. Now i can't even pull on the pull cord (can even budge it) Just wondering if you have any ideas on what could be wrong.

Hello Trevor:

>>Sorry for the Delay. This Question was Located in the Question Pool and I can Only Answer Questions from the Question Pool when I am Not Answering Questions here or at the Other Site I Answer Questions at.
>>From your Description (especially the Screaming) it Sounds like the Starter Clutch is Binding and Requires Cleaning. The Rope is Most Likely Bond Up in the Blower Housing and is Preventing the Engine from Turning.
>>The Following is a Basic Instruction File I made for Cleaning the Most Common Pull Starter Clutches. Any Input is Appreciated.
>>Remove the Blower Housing (Metal Engine Cover). This will Give you Access to the Starter Clutch.  
>>This has Several Ball Bearings in it, so be Careful when you Remove the Solid Cover.
>> Secure the Crankshaft, Remove the Wire Screen from the Starter Clutch.
>>Use a Small Thin Standard (flat) Screwdriver (I Use a Pocket Screw Driver All the Time or a Putty Knife is Easier for Most Questioners) and Pry Off the Cover.
>>You can Now Clean and LIGHTLY Lubricate the Bearings, Ratchet Spring Adapter (there is no Spring. it is called the ratchet spring adapter because it adapts the starter clutch to the Recoil spring and rope assembly in the blower housing) and the Starter Clutch Support Section of the Crankshaft.
>>Make Sure there is No Rust or Dirt in the Support Section of the Crankshaft and LIGHTLY Lubricate this Area Also.
>>Once the Starter Clutch is Clean, Place the Center Component of the Starter Clutch (the Ratchet Spring Adapter) into the Starter Clutch Housing and then Put the Bearing Into the Housing. Then Tap the Starter Housing Cover Back Into Place. >>Reassemble the Rest of the Components and you are Finished.
>>**If you have a Different Style Starter; then Send me the Make, Model, Type/Spec Numbers Off the Engine, Please.
>>Just in Case you have to Remove the Starter Pulley to Repair the Recoil Starter, I have included the Following File.
>>The Following is a Basic Recoil Starter Repair Instruction File. Any Input/Suggestions are Appreciated. Remove the Starter Housing/Engine Cover. Remove the Old Rope (the Rope is Not Installed onto the Pulley Until AFTER the Spring and Pulley are Installed into the Housing. All will be explained later in these Instructions), Pulley and Spring from the Blower Housing. Clean the Housing. Now Take the New Spring and Locate the Housing Lock Hole that is Usually Near the Pull Handle Hole. Slip the New Spring Into this Hole and Lock the End Onto the Pulley. Now Lock the Pulley Into the Blower Housing. Turn the Pulley in the Same Direction that it would Turn During the Starting Process. The Spring will be Pulled Into the Blower Housing as you Turn the Pulley. When the Spring is Almost All the Way Into the Housing; Hold the End with Pliers and Make Sure it Catches in the Blower Housing Lock. Once the Spring is Locked Into the Housing, then Continue Turning the Pulley in the Same Direction that the Pulley would Turn if the Rope was Turning it. Once the Pulley will Turn No More, then Reverse Direction 1 or 2 Turns and Thread the New Rope Through the Hole in the Center of the Pulley and Out the Hole in the Blower Housing. Pull the Rope Through Until it is Tight Against the Pulley. Now Tie a Slip Knot in the Rope to Hold the Pulley in Place While the Handle is Attached to the Rope. Once the Handle is Attached, Release the Slip Knot and the Rope Should Retract Into the Housing. Reassemble the Blower Housing Onto the Engine. On Some Models you May have to Install the Rope Before you Lock the Pulley in Place. If So, there is a U in the Pulley that the Rope is Held in While Turning the Pulley to Tighten the Spring. These are for Most Recoil Starters. If these Instructions are Not for your Recoil Starter, then Send me the Model Numbers Off the Unit, Please. With these I can Locate the Proper Manual and Better Assist you.
>>If you Hit a Snag or this Does Not Correct the Problem,  I am Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Be Safe and Happy. Thanks.

Good Luck

Respectfully

John
