QuestionQUESTION: Hi Mr Bridgers:
I am trying to help a single mom out with her 9hp Briggs.Dont know the age,though.The engine ran last year when it sounded like it ran out of gas.He 15y/o son supposedly added gas...it would not fire up again.I checked the fuel take and no gas had been added.He had added the gas to the crankcase!!
So,this year...I have drained the bad oil out,cleaned the carb bowl and needle valve.
Pulled the plug,which was gapped less than .020...regapped to around .035.
First turn of the ign.key...it fired up and sounded pretty good;but,the muffler began "spewing" out quite a lot of old gas/oil mix...and,obviuosly smoking.
I shut it down and waited 10 mins and fired it back up...same thing happened as it began to heat up.
What has been your experience on something such as this?
She lives rather remote and limited resources to a repair shop.
Thank you for your time,energy and experience.
ANSWER: Hello Rory:
From your Description it Sounds like the Crankcase Breather Requires Cleaning. Also, 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. The Model Numbers May be Stamped Into the Blower Housing (metal engine cover) Above the Spark Plug. Remove the Muffler and Run the Engine. The Muffler May have had the Gas/Oil Mixture in it and it Takes about 1/4 Hour for the Muffler to Clean Itself. If this is an OHV Engine, then the Head Gasket May be Blown between the Push Tube Galley and the Compression Chamber. 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. Thanks.
Good Luck

QUESTION: Hi John:
Hope you have had a Good Easter and are doing well.
When we last talked,you asked me to get the #s for the mower...finally,I found her home!
Mod.#28A707
Type-0122 02
Code-9505104E
The spark plug I removed and regapped was a 3/4 socket fitting.I had been told that that may be the wrong plug...that it should probably be a 13/16(?).
Havent started it back up since our last message.
I plan to replace the makeshift gasket on the center bowl nut with a proper fiber washer....I have not checked to see if any of the silicon might have broken off and made it up the fuel pick up tube causing the float to hang up...could be that may be some of the problem.
Today...I also smelled that fresh oil and that has a gas odor to it.Maybe left over(?).
So,need to get proper plug and then...what??
Rory
AnswerHello Again Rory:
Thanks, My Holiday was Good and I Hope yours went Well Also. 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 (first 4 digits Only). Example: 28A707-0122. Then Double Click on the Model in the Results Area. Now you can Select the Section of the Engine you Wish to View. I Suggest; 1- you Install a Manual Cut Off Valve in the Gas Line and Tell the Owner to Turn Off the Gas Flow when the Mower is Not in Use. 2- Replace the Muffler. 3- Clean or Replace the Crankcase Breather. 3- You May Need to Soak and Clean the Carburetor if the Float Needle Valve is Not Seating Correctly. To Properly Clean the Carburetor; **Remove, Disassemble and Soak the Carburetor Overnight in Carburetor Cleaner (I Use Gunk). I have Found that Most People can Use a Breakdown/IPL and Disassemble the Carburetor Enough for Proper Cleaning. You Only have to Remove the Bowl (if Applicable), Float Pin (if Applicable), Float (if Applicable) and Needle Valve and Any Adjustment Screws that Go Into the Carburetor Body. The Welch Plugs Do Not have to be Removed. Then Soak the Carburetor Body and Parts in a 1 Gallon Can of Gunk Carburetor Cleaner Overnight. The Can has a Parts Tray Inside it for the Small Parts. Once the Carburetor and Parts are in the Cleaner, you can Replace the Lid for Safety and to Prevent Accidental Spillage. Then Blow Out the Passages with Compressed Air. Install New Parts if Required.** The Spark Plug for this Engine is a Champion # RJ19LM and I Believe it Requires a 3/4" Socket. 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. Thanks.
