Question
QUESTION: I am rebuilding a 38120 2-cycle Tecumseh.  What is the best way to re-install the needle bearings when I "stuff" the piston?

ANSWER: Hello Jon:

>>Most Mechanics use White Lith Grease to Hold the Bearings to the Crankshaft, but I have Found that Replacing the Bearings is Best.
>>Send me the Model and Type or Spec Numbers Off the Engine, Please. With these I can Locate the Proper Manual and Better Assist you.
>>Thanks

QUESTION: I believe the "dog tag" on the engine says  "1585  Tecumseh 8090"
I have the engine put back together, but I cannot get it to fire.  I put a little fuel in the spark plug hole, but still nothing...like it's not even getting a spark.

Answer
Hello Again Jon:

>>You can View a Breakdown/IPL at this Site Addy,
http://www.emerichsales.com/ and Select Tecumseh Power Company in the Drop Down Under "Parts Lookup" at the Left of the Page. Now Fill Out the OEM Part Diagrams Look Up by Model Fit.
>>Select the 2 Cycle Horizontal Engine. Now Select the 1500 Series Engine. Now Select the 1500-1585 Engine. Now Select Engine Parts List.
>>There is a Breakdown with the Engine Parts List.
>>Did you Replace the Point Set?
>>There is a Points and Condensor Under the Flywheel and Usually the Condensor is the cause for No Fire to the Plug.
>>Check for Fire at the Plug. If No Fire at the Plug, then
>>Remove the Flywheel and File the Point Set Contacts with a Finger Nail File and then Assemble the Flywheel and Check for Fire at the Plug.
>>If Still No Fire at the Plug, then
>>Replace the Point Set.
>>The Following is a Basic Instruction File I made for Removing the Flywheel and Replacing the Flywheel/Flywheel Key.  
>>Remove the Cover that Houses the Starter Assembly.
>>Remove the Spark Plug and Use a Bolt the Same Diameter and Threads as the Spark Plug and About 3" Long.
>>Thread the Bolt into the Spark Plug Hole Until it Engages the Piston.
>>Slowly Tighten the Bolt Until you have Locked the Piston and it Does Not Move. **BE CAREFUL A LOT OF TORQUE IS NOT REQUIRED. PISTON DAMAGE CAN OCCUR IF TO MUCH TORQUE IS USED ON THE STOP BOLT**
>>Now Remove the Flywheel Nut.
>>Use a 3 Jaw Puller and Attach the Puller to the Flywheel.
>>Look for a Puller with Flat Jaws. These Slide Under the Flywheel and Allow for Easier Removal.
>>Tighten the Puller and then Hit the Puller with a Hammer. Tighten and Hit Again Until the Flywheel is Loose and Can be Removed from the Crankshaft.
>>Now Remove the Cover Over the Point Set.
>>Place the Crankshaft so the Lobe on the Crankshaft is Opening the Point Set and then Set the Point Set Gap to .015in.
>>Assemble the Engine and Now the Spark Plug should Fire.
>>As Always, 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. Have a Happy Holiday Season and May the All Mighty Bless You and Yours. Be Safe and Happy. Thanks.

Good Luck
