Questioni replaced connecting rod on a briggs and stratton model no. 124t02-0854-e1 and it wont start, i believe i have the timing off.
i took a pic of location of crank and cams position and put it back together with the pic looking the same. and when i turned the crank the timing marks hit. but it still wont start and it does have spark. is there an ez way for you to tell me how to make sure im at tdc to ensure the timing is correct as ive opened up the case and moved the crank 180 twice now, and i even bought a new plug for it.
AnswerHello Tony:
>>There is a Mark (- or a .) on the Crankshaft Gear Tooth and a Dot(.) between the Teeth on the Cam that have to be Matched for the Valve Timing to be Correct. Usually the Larger Dot (on the Camshaft) is the Timing Mark.
>>Did you De-Glaze the Cylinder while the Piston was Out of the Cylinder?
>>Did you make sure the Rings End Gap were Correctly Aligned when you Installed the Piston into the Cylinder?
>>Usually when a Piston is Removed from the Cylinder you have to De-Glaze the Cylinder so the Rings can Re-Seat to the Cylinder and the Engine can have the Correct Compression to Run.
>>Removing the Piston causes the Compression and Oil Rings to be Unseated and Honing/De-Glazing the Cylinder is Required for the Rings to Re-seat again.
>>The Engine may have Compression, but Not the Required Compression to Run.
>>Try Removing the Spark Plug and Adding a Small Amount of Engine Oil (1oz) to the Cylinder and Replace the Plug and Try to Start the Engine a Few Times. It Will be Hard to Start and will Smoke when it Starts (if it does).
>>If the Engine Starts with the Oil Added to the Cylinder, then you may have to Remove the Piston and De-Glaze the Cylinder with a Cylinder Hone.
>>Have you Checked the Compression?
>>Is the Flywheel Key Damaged?
>>You can View a Breakdown/IPL of this Engine at this Site Addy, http://www.smallenginepartswarehouse.com/parts.asp and Select the Shop Online Parts Look Up. Then Select the Model Tab. Then Select the OEM and Enter the Model (5 or 6 Digits) and Type Numbers. Example: XXXXXX-XXXX-XX. Then Double Click on the Model in the Results Area. Select Sectional Index. Now you can Select the Section of the Engine you Wish to View.
>>If you Hit a Snag or this Does Not Correct the Problem, I Hope to be 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
