We would find it useful to know what machine the engine is fitted to.
Thank you

How do I remove the piston from my Briggs and Stratton 17hp horizontal shaft mower?
if the piston big end bear is removed and the piston will not come out of the bore because something is stopping it , it will be from a wear ring area at the top of the bore (wear ridge)
it is where the top ring stops and there will be a lip down the bore the distance from the top of the piston to the first ring
all cylinders wear big at the top to normal at the bottom ( wear taper) and the ridge is formed over time from wear or in the case of small engines from a failed air filter which allows accelerated wear of the bore ( dusted engine) and produces a ridge that the top ring jams on so preventing piston removal
to remove it you can buy a ridge remover tool from a good tool shop or auto spare shop or you can get a small grinder wheel in a drill and just grind the lip section off.
provided you restrict the grind to no lower than the lip it will not affect the engine

2005 toyota corolla blowing smoke
Blowing black smoke means fuel mixture is too rich, possible choke is stuck partically closed.
Blowing white smoke especially driving off the traffic lights indicates either worn valve guides or worn piston rings. Valve guides require the head to be removed to replace valve guides.
Replacing piston rings means a major engine repair. It maybe better to get a reconditioned motor than replace worn piston rings because other worn engine parts should be replaced at the same time.

Replaced rings and honed the cylinder but its scored up again and the rings were stuck in the piston and were hard to remove
Your description indicates when the engine started the piston wasn't receiving any lubrication or maybe the rings were too tight or both and the engine suffered pre-seizure.

It is well to observe the basics with these sort of things and take nothing for granted. Prior to fitting piston rings it is important to check the ring end gaps. Most popular repair manuals will have diagrams about this and the recommended gap for your engine which is likely to be something like 4 - 6 thou per inch of bore. Quite often the piston ring ends must be filed a little...

In addition it is important to ensure the piston ring grooves have been thoroughly cleaned of carbon and the rings fit well with a side play of 0.0015 inch. A little more is permissible and perhaps as much as 4 thou for the top ring but more than that and the piston should be replaced.

Have oil in one of the spark plug cylinders what would be causing this ?
broken/worn piston ring(s). Each piston has 2 rings. These can be replaced by the DIY mechanic by
1) removing head of engine (remove head gasket - you'll replace it), then
2) manually wind the engine (with a ratchet wrench & socket) til the piston in question pops up
3) remove both rings (with ring pliers - available from any auto parts store)
4) install 2 new rings (with a ring installation collar - available at any auto parts store)
--- choose ring installation tool to the correct size for your pistons.
5) re-install head of engine (replacing head gasket)

Note that this procedure preserves the engine timing, so you need not reset it.

HI, I have a Suzuki LT80, it starts ok but it smokes like hell and there dosnt seem to be much compression what could this be? thanks.
It seems you have worn rings and/or barrel and piston. You will have to get the barrel off the engine to ispect. Unbolt the carb and exhaust from the engine. Unbolt the 4 nuts on top of the head. Remove the head and barrel from the engine. Inspect the piston for scoring and wear. Remove the piston by removing the circlip next to the gudgeon pin. Do not drop the clip into the engine.(stuff some clean rags in the engine under the piston. The gudgeon pin can now be pushed out of the piston and the piston removed.Have the barrel and piston measured for wear.
If you're on a tight budget you can replace rings only but this is a penny wise pound foolish solution. You'll have the same problem in 2 months time.
It is best to rebore the barrel and fit an oversize piston and new rings. The barrel can also be resleeved but this is a more costly option and should only be exersized if you cannot obtain an oversize piston.
