Time to put the Ole Dog to Bed ! Pick up a replacement Engine and retain the chassis for rebuilding the current engine is a waste of time and effort .

If it is seizing up after being run hard while tilling it may be overheating. Reomve the fan shroud and clear out all the stuff that may have accumulated over 10 years.

I checked when I got and the block is clean.

Are you sure it is the engine seizing? Could it be in the drive line, transmission or tiller?

It is the engine. It does it without the belt on. Once it gets up to temp it seizes. The oil only has about 1 hour run time on it (Citgo SAE 30) I pulled the cylinder head and the cylinder is pretty much destroyed. This is an aluminum bore also

I wonder if it wasn't run dry or seriously overheated sometime earlier in it's life.

It's possible. This belonged to my neighboor and he never checks oil or takes any care of his equipment.

Mental Note , Don't buy any mechanical equipment from A/C's Neighbor unless its for Metal Haulage to the Dump for Cash lol !

Any time I get something from him I'm leary about it. This tiller is pretty light duty and not high quallity.

Well...just till for 18.5 minutes, shut it down for 10 minutes and get a drink of water. It works, but don't put a nickel into that beast - just run it conservatively until it dies. Hope you didin't pay money for the tiller.

It was free so no loss. I've been trying to kill for good ever since it started doing this it but it won't die

I can just see it now ...Sorry Dear but I had to let the Tiller Cool down so I had another Beer ..Roflmbo !

Haha. It runs seizes up. Put the visegrips on the pulley and turn it. Fire it back up and do that again. Maybe I should drain the oil :)

Yeah, run it without oil for about 10 minutes and loosen up those tolerances some!

8 trys with no oil and it stil goes. Barely any compression now. I wanted to lock it up for good but it keeps on going like the energizer bunny

So...set it up for Electric Start with an extended ("Extension Cord") and sit back and Crack another Beer and Wait for the fires Works lol ! :) .

It pretty much has no compression anymore. I fix small engines as a hobby but trying to blow this one up has been fun. Maybe I'll try water and metal shavings tomarrow

a-c : We should have established some side bets on how many attempts till meltdown lol :)

Try a 70/30 mix of oil and valve lapping compound!

Thanks for the idea Roadbike! lol

Well I officaly give up. I tried water and metal shavings in the crankcase. Has no compression now but still spins over. I guess 3hp Briggs are tough

Yeah the Old B&S Line were Die-Hards lol :)

This thread made me ill, like reading an account of animal abuse. I would have taken the approach of trying things out to see if it could be made better, like Opti-4 oil, which improves rubbing surfaces. But, whatever, it's dead now and the torment is over. :)

Walked by it today and she goes. It's starting to screech now when it runs and it gets harder to pull over now. Lol

Sax , Cover Eyes and Ears Roflmbo...Better than Animal House !

Hahaha.

Well it finally went. Locked up tight and snapped the rod

Whens the Wake I want front row seating !

The Wake will be tomarrow night at 6:00

Did it go with a bang or a whimper...

It went bang

1st Bud'd on Me lol :) .

Note: All kidding aside B&S broke the mold when they discontinued their Old 3-HP , Great Little Work Horse!

ewalk: Briggs broke the mold when they put emissions carbs on the old flatheads and then discontinuted them
