What causes too much compression in a chainsaw?
Many problems with compression are related to fuel. Old or bad fuel can cause lots of headaches with yard equipment. Try draining any of the gasoline mixture left in the gas tank and add fresh fuel. If this does not solve the problem, it may be related to excessive fuel caused by problems in the gas lines and filters.
How do you start a chainsaw without a cord?
There are four different ways to start a chainsaw easier or without pulling the cord:
- you can also start your chainsaw with a drill.
- Spring-assisted starting system.
- Capacitor discharge ignition (CDI) or Memory power ignition (MPI)
- Automatic High idle mechanism.
Why is my pull cord hard?
Some common issues that can lead to a cord being harder to pull are hydro locking, which usually occurs because of oil spilling into the exhaust area, and a misshapen crankshaft. The misshapen shaft can generally be detected due to the noise it makes.
How do I stop my chainsaw kickback?
Ways you can avoid chainsaw kickback
- Read the manual.
- Make sure the chain brake works before you start.
- Use low-kickback chains.
- Use a sharp chain.
- Be wary when felling tree trunks.
- Pay attention to the nose of your chainsaw bar.
What makes a chainsaw hard to start?
The chainsaw’s engine is flooded with fuel. A fuel issue is one of the most common reasons why a chainsaw won’t start. If the operator has repeatedly been trying to start the chainsaw through the recoil starter system, they may have accidentally flooded the engine with fuel.
How do you make a chainsaw start easy?
Activate the choke by moving the lever to the full choke position and pull the starter rope 3 or 4 times to start the engine. If that doesn’t work, move the choke lever to half choke and pull the starter rope, 6 times maximum, to start the engine.
What causes a chainsaw to vapor lock?
Vapor lock occurs when the fuel (usually gasoline) within the fuel delivery system overheats and vaporizes too rapidly. The resulting excess gas bubbles accumulate to the point of actually blocking normal fuel delivery.
What causes low compression in a chainsaw?
If you do notice the rope slowly extending, then the chainsaw compression is most likely low and needs checking more precisely. The most common places for an air leak to occur are on the crankshafts seals. Damage to the piston or the piston rings may also be the cause of the problem.
Why does my chainsaw have low compression?
Problems with the compression usually occur due to an air leak somewhere inside the internal engine, generally around the gaskets and seals of the crankshaft. If these parts are cracked or broken, the entire engine will need disassembling before the problem will get resolved.
How do I make my chainsaw easier to start?
Try to start the chainsaw after priming the carburetor. 5. Activate the choke by moving the lever to the full choke position and pull the starter rope 3 or 4 times to start the engine. If that doesn’t work, move the choke lever to half choke and pull the starter rope, 6 times maximum, to start the engine.
What makes a chain low kickback?
The thicker the chip, the more severe the potential kickback. To minimize the possibility of reactive forces, kickback-reducing features on chains limit the amount of fiber that can be hooked by the working corner as it rounds the upper half of the bar tip, which is commonly referred to as the kickback zone.
