Small Engines (Lawn Mowers, etc.): transmission lubing and carburetor disassembly, briggs and straton, synthetic engine oil


Question
I have a 1997 Ranch King 42" cut riding mower,model #13AM675G205 with a Briggs and Straton, 14.5 hp engine, model #2877070224-01.  The transmission is a model #618-0163A or B? It reads "A" but the MTD Products website only lists a "B" suffix.  I have verified my year as 1997 by cross-checking with the transmission and engine model numbers.  I bought this mower used and was told it hasn't been run since the summer of 2005.  I've degreased, cleaned, lubed, put tubes in 3 of the tires, replaced the battery, spark plug, fuel filter, cleaned the air filter, wire brushed the rusted flywheel magneto contact points, etc.  

Question #1:  I noticed a heavy accumulation of grease and dirt all along the seam of the transmission.  Can I put more grease or heavy rear end oil into it?  I can't find a plug to pour into or grease fittings to squirt into.

Question #2:  My son-in-law told me I needed to get any old gas out of the carburetor bowl and make sure the needle isn't plugged.  I've rebuilt motorcyle carburetors; but can't find how to get into this one.  There appears to be a bowl on the bottom with an electrical connector attached with a plug and a couple of wires on the bottom of it.  Does the bowl unscrew?  I don't want to force it and risk breaking it; but can't see that it is held on with clamps, bolts or the like.   

Thanks for answering two questions,

 Hello John:

 Place the Transaxle Shifter in Neutral and Remove the Shifter from the Transaxle. Add 1qt of SAE40 Mobile 1 Synthetic Engine Oil to the Transaxle. Check for Loose Housing Bolts on the Transaxle. Go to this Addy http://www.outdoordistributors.com/ and Click on the B. Then Select Briggs and Stratton. Then Select Don't have Part Numbers. Then Select File Number 28. Then Select the Folder # 287700. This will Download a Breakdown of the Engine. There is a Breakdown/IPL of the Carburetor in this Folder. The Solenoid Unscrews from the Bowl of the Carburetor. this Solenoid, if Bad will Prevent the Engine from Starting. It Shuts Off the Gas to the Bowl and the Carburetor. If the Engine hasn't been Run in a While I Suggest you Soak the Carburetor Overnight in Gunk Carburetor Cleaner and then Blow Out the Passages with Compressed Air. Install New Kit. You will have Less Trouble if this is Done. Hope this Helps. I am here if you Require more Assistance. Let me know what Happens, Please. Thanks.

 Good Luck

 Respectfully
