QuestionQUESTION: I installed new breaker points on a H50-65422L Serial # 9441D then installed a Tecumseh dial indicator at .080 BTDC ,then disconnected the leads from the pts terminal and resecured the nut.Then I installed my continuity tester.The alligator clip to the pts terminal and the other lead I clamped to ground.I had a hard time to get the light to go on or off to set the pts by loosening the strator bolts & rotating the strator plate.Any help would be appreciated.I still dont think there set right.Thanks Herb
ANSWER: Hello Herb:
>>You must be Using a Tecumseh Manual.
>>Return the Point Set Stator Plate to it Original Position and Use the Following Instruction File to Set the Point Set. Ignore Anything about Moving the Stator Plate to Set the Point Set Gap. They make it so Complicated and it is Really so Easy to Gap the Point Set.
>>The Following is the Instruction File I Made for Removing the Flywheel and Replacing the Point Set of Most Older Mower/Blower Engines. It is the Basics and if you have a Question, Please Ask. Any Input to Make this File Better is Appreciated.
>>***Disconnect the Coil Wire from the Spark Plug. Remove the Blower Housing (metal engine cover).
>>Remove the Coil.
>>Remove the Flywheel Nut or Starter Cup (Depends on the Model).
>>Now Attach a Steering Wheel Puller to the Flywheel Using the Threaded Holes in the Flywheel.
>>Tighten the Puller. Now Hit the Puller with a Hammer. Repeat this Procedure Until the Flywheel Pops Up or can be Lifted Off the Crankshaft.
>>On Some Models you Can Not Use a Puller and Must Use a Pry Bar and a Pipe Cap that is Slightly Larger than the Crankshaft. Place the Pipe Cap Over the Crankshaft to Protect it. Place the Pry Bar Under the Thick Section of the Flywheel and Pull Up Against the Flywheel. >>**BE CAREFUL DO NOT PUT A HOLE IN THE BLOCK UNDER THE FLYWHEEL** >>Now Hit the Pipe Cap that is on the Crankshaft (covered with the Pipe Cap). Repeat the Procedure Until the Flywheel can be Lifted Off the Crankshaft.
>>*** Be Sure you have the Flywheel Torqued to the Proper Torque (I require the Model and Spec/Type Numbers Off the Engine to Provide the Proper Torque) and Set the Coil Gap to .020in.. A Cardboard Side Panel from a Drink Carton will Work for Setting the Coil Clearance.
>>The Point Set is Under a Cover Under the Flywheel. The Point Gap is Set by Slowly Turning the Engine By Hand and Holding the Point Set Plunger with your Finger. When you Feel the Plunger is at the Outer Most Point of its Movement, then Stop Turning the Engine and Using a Blade Style Feeler Gauge, Set the Point Set at .015in or .020in. (the correct Gap is usually Stamped on the Metal Point Set Cover. if not then .015in is good).
>>On Tecumseh Engines, Set the Point Set into Place and Snug the Set Screw. Turn the Engine Until the Crankshaft Lobe that Actuates the Point Set is Fully Up on the Point Set Ear. Using a Flat Screw Driver, Open and Close the Point Set Until a Blade Feeler Gauge will Slide between the Contacts. Set the Gap to .015in and Lock the Point Set Down. **Do Not Loosen or Move the Point Set/Stator Plate. This is Not Really Required and it is Easier if Performed the way I Described and Not the Way the Tecumseh Manuals Suggest.**

QUESTION: When I checked the flywheel key there was about 1/32" -1/16" movement in the flywheel when I rotated the flywheel before tighting the nut.Tried several new keys and the best I could do was about 1/32" movement.After assembling the engine it starts on 1 pull but I can hear a slight miss.Do you think this is the problem.The play seems to be in the flywhhel not the crankshaft.Any suggestions on remeding this issue?Is flywheel replacement the only option? Thanks Herb
AnswerHello Again Herb:
>>If there is Wear in the Flywheel and the Key is Allowing Backlash, then a Flywheel is the Only Way to Correct the Backlash Problem.
>>From your Description the Amount of Backlash should Not Cause the Slight Miss you Described.
