Old Briggs 11 HP.030 OS piston needed. Suggestions for places with best price.

Hello

It's been a while since I've posted here. Things have been busy.

I have an older Briggs (mod 252707) that has a worn cylinder due to a broken ring. I think I have a source on reboring it.

Here's a short video of me checking the amount of the movement of the piston.

This is before I tore it down.

I've seen OS piston and ring sets available for around $60.00+ Anyone out there have a favorite web site with good/great prices? I'll also be needing a full gasket set.

Thanks for your replies!

Dan

I hope it's okay to post a link to a place where I found a good price on an OS piston.

23-6727 - B&S 391289 Piston Assembly (+.030) | Small Engine Parts | MFG Supply

$41.65 with $7.00 shipping. Not too bad. I'll keep looking.

The reason it is dying at about the same period of run time is because your valve clearance are too close due to block warpage from overheating/wear etc.

As far as repairing this block, forget about it, it is toast. If you go halfway down the slop is greater than .030, as cylinder wear
is never even going down the stroke, and you will just be wasting time and money messing with it any more.

A shortblock is a possibility, but the carb is likely worn out, and dirt probably flows pretty freely through the throttle/choke shafts.

Just check out the engine warehouses online, and they will set you up with a new engine, but putting one on an old cone drive Dixon, that is another discussion, personally, I would look for another mower.......

I agree that the block is probably worn out. I took another engine off of another mower that runs. Yes, cone drive is old stuff. I'd like a hydro drive.
