Decespugliatore 2 tempi a miscela; smontaggio completo gruppo termico

Seizure and wrong mixture in the 2-stroke engine: let's disassemble everything! 🔧🔥 In this video I completely disassemble the thermal unit of a 2-stroke mixture brush cutter, to analyze the damage caused by an incorrect mixture and the seizure of the engine. I share assessments on restoration costs, comparison between 2-stroke and 4-stroke, and useful tips to avoid these errors. A video not to be missed if you want to make your engine last! #Brush Cutter #SeizedEngine #EngineRepair Attention, below, there are Paid Links.

The 2-stroke engine seizes (i.e. it blocks due to internal friction) when there is a lack of correct lubrication or extreme overheating conditions occur. Here are the main causes. Lack of lubrication in the mixture: if the petrol/oil mixture is too lean (i.e. with little oil), components such as the cylinder and piston are not lubricated adequately, generating friction and heat → the piston expands too much and blocks in the cylinder. Use of the wrong or poor quality oil: oils not suitable for 2-strokes or of low quality do not resist high temperatures, do not protect well and leave harmful residues. Old or poorly preserved mixture: oil separated from petrol or degraded loses its lubricating properties, with the risk of seizure. Engine overheating: can result from too lean carburetion, clogged air filter, wrong spark plug or insufficient cooling (e.g. dirty cylinder fins). Incorrect carburetion: if the carburetion is too lean (i.e. too much air compared to petrol), the combustion is too hot → increases the risk of seizure. Clogged petrol filter or dip tube: causes less mixture to reach the engine → lean mixture → seizure. How to prevent it: -Use fresh mixture with the right oil/petrol ratio (e.g. 1:50 or as per the manual). -Use good quality specific oil for 2 strokes. -Check the carburetor, air filter, and cooling system. -Avoid revving the engine as soon as it is started or when it is hot and dry.
