Chipper help

[philip2011]

Quick question I have bought a little bearcat 180 (3 inch) chipper has Briggs and Stratton engine possible sizure 

1 best place to buy a new engine if.needed going to investigate More.tommorow

 

2 i can turn the drum where the blades are located does this mean the engine is sized?

I would imagine it has a centrifugal clutch, so the drum tuning is ok.

 

But not a machine I’m familiar with, so I could be wrong.

A bit more info would be good! Is it pull start? Can you pull it over? Is it key start and battery okay? We will try to help but info is good!

Ok sorry it's a 4 stroke. Pull start engine 8hp b&s you can pull 5/6 inch of.cord out then it.wont go any further hope this helps

are you sure it's simply not a case of the drum is jammed up with some twigs?

[philip2011]

No as I can turn the drum freely wit no issues. My question is if the drum turns does this mean that the  engine is sized?

When it wont pull over any more is it because the engine is coming up on compression or is the stop a bit more "mechanical"?

 

Take the plug(s) out and try turning it over, if it still locks up it might be "mend it with a new one" time

As you pull the cord out does it feel like it’s turning the engine over or is it just taking the slack out of the pull-cord mechanism (ie the engine is completely seized). 

I’ve managed to free of a seized (water in the cylinder and left to rust) Honda GX engine before now by pouring a load of wd40 down the plug hole and leaving for a couple of days then cracking it over with a bar on the end of the crank - it still runs perfectly on our jetwash 5 years later but it was a lucky save (and I only attempted it as a last resort before binning the engine).

Went and got a new engine Today back  up running will look at the engine at a later date if I have time

have you left the fuel turned on and the cylinder could possibly have filled up with raw fuel
