Its the oil injection tank. This is the oil that mixes with the gas. Without and oil/gas mixture your 2 stroke motor will be ruined due to lack of internal lubrication. Some people will disconnect them and premix the gas due to a fear of failure of the injection system.

Maxtra is a cultivator, a motorcycle, a pole saw or a water filter - according to google and probably more besides. Obviously the lack of specific information limits the advice we can offer.

Lots of 2-stroke owners these days prefer using synthetic self-mixing 2-stroke oil these days and so if 50:1 is the ratio recommended for your machine you will be ok.

Chain lubrication is a subject for discussion. If a standard old-fashioned roller chain the traditional approach offers a longer life and less wear. Removing the chain periodically and boiling it in a thick black moly grease, leave it to cool and then fish it out, wipe off the surplus grease and refit it. Use a proprietary external chain lube betweentimes whenever the chain appears dry.

Modern drive chains are often O ring types that need only external lubrication and for these I recommend a moly based chain and cable lubricant. It is available in an aerosol and sprays like penetrating oil but when exposed to the air it thickens after a few minutes to a very sticky grease.

If my memory is working, a two stroke engine uses oil in the fuel for lubrication. four stroke has oil in a crank case for lubrication.

Non detergent 30w mineral or synthetic

The biggest contributor to that is the engine running too lean, then the plug rating is too hot, then timing.

hey mate, have a look on google. just type valve clearance for your year make and model of bike.

It is most likely oil. Probably passing past the rings on the piston. I use 2 stroke oil in all my mowers / small motors whether they are 2 stroke or 4 stroke (based on advice from a small motor repairer) since the 2 stroke oil helps lubricate the bore and even though there is some minimal smoke usually on start-up. Depending on how bad the smoke is you can try a heavier grade oil and I would recommend using a 25:1 2 stroke mix if you want to extend the life of your small motors.

If the piston is working in the cylinder properly, that part of the piston shouldn't be making contact with the cylinder wall so lubrication shouldn't contribute to its demise unless it was bad enough to lead to enough heat buildup to cause the failure. It is most likely the metal was weak in a way or spot that the force of the piston going up and down was enough for the metal to finally fail. Of course the faster the motor is turning the higher those forces are so over reving the motor could certainly lead to this type of failure.

If this is a 4 stroke engine it sounds like a simple fuel delivery problem. Clogged filter, or screen or a restriction from debri in the carberetor.
If it's a 2 stroke it could be running lean and the cylinder is overheating. This may be doing damage to the cyl. walls. Don't run it until diagnosed.
A lack of proper fuel leads to lack of lubrication in 2 stroke motors, lean mix causes high heat to build and soon you have a heavily scored cyl and piston.

Hi and welcome to FixYa, I am Kelly

First off the engine is designed to operate on unleaded fuel. The manufacturer makes no statements at all about E-10 Fuel. I will tell you from experience that you can use E-10 Fuel but.... should you ever have a warranty claim make sure the entire fuel system is 100% unleaded pre-mixed fuel. Your not going to hurt the unit using E-10 fuel as long as you maintain the proper fuel-oil mixtures. If anything a splash more of 2 stroke oil as in 22 mm / liter vs 20 mm. Or (+) 8 mm per gal.
