I noticed you have 3 posts in a row in 9 minutes on just this thread alone. Instead of posting each 3 minutes, you can edit one of your posts and add to it instead of starting so many. You now have 30 posts in 1 day and some posts are just asking for our opinion. We already know this is what you want. Get your post all written and then sit back and wait for someone to answer it. If all 4545 members wrote 30 posts a day, we would run out of room on the internet in a few days. ;)

351M Windsor laying around it should have enough power for your mower.

Ok guys. Time to "revive" this thread. LOL. I was wondering, is it worth it to put an oversize piston and ring set in my old 7HP B&S? I want to try to keep the whole mower and restore it somehow. That engine's cylinder bore is so worn out, every time I give it the gas it smokes like a bug fogger!!! Any suggestions?????????:)

If you do overhaul your old B&S, please, please be sure you take it to a well know machine shop that deals in small engine.
I bet you will find that the cylinder will need to be borded and the crank will need to be turned.
If these steps are not taken, all you will do is throw good money down the drain if you just re-ring it.

My luck rebuilding:B&S aluminum bore motors is about the same as finding that 5 mill lottery winning ticket on the street in front of my house-It just doesn't go right either way. I talked with a B&S rep a few years back and he said after they hone the bore they spray it with some coating. If your trying to keep it original have you looked for a short block? If nothing else,An 8hp B&S uses the same shroud, carb,starter muffler so you at least can make it look right.

I have worked at a small engine shop and have alot of experience with briggs mortors and it is always the same by the time you bore hone mill/turn the crank and buy parts it is cheaper to buy a bran new mortor. a good place to buy mortors is through NOTHERN TOOL they run:

Birggs 8H.P314.99

8HP tecumseh
with recoil is 249.99
with electric start 329.99

I hope this will help you out

have you checked the cylinder wear? it could be blowing blue smoke from a stuck oil ring or plugged up crankcase breather. if you want to keep it original, why don't you tear it down and rebuild it with everything you've learned here. give me the model,serial and type #'s and I'll see how much the repair parts would be. probably not more than $50.00

Ok, Khouse. The model is: 170702, type: 1517, code:80032709. Thanks. Be back soon:)

Yes sir, that cylinder is very worn out. We noticed it the time we overhauled it. We honed it out to get some scratches out, and it's been that way ever since we put it back together. It's definetly the cylinder bore. Thanks a 'gin, Khouse!:)

robert,
new rings,both valves,carb kit,gasket set,seals,plug,standard piston,air filter are about $85.00 aftermarket. I'm not saying bore it out,turn the crank - that would be a waste of money. I am saying to get some practice put a new piston and rings in the loose cylinder, do a valve job ect. All for under 100 bucks. It will probably run 3 to 5 years pretty good - maybe more. you need to tear one of your worn out engines apart yourself and try to put it back together. it's not like your tearing down a $2000.00 engine. get your hands dirty.

Yeah. That's a good idea. That engine could use another overhaul!!:cool: Thanks a million!:) By the way, we bought Briggs and Stratton brand parts on the last overhaul.:)
