Episode 55: This is a Common Cause of 2 Stroke Damage (Chainsaw, Trimmer etc)
* VISUALLY EXPLAINED by Craig Kirkman, a renowned you tube educator of these systems.
Very few people know this, but there is a very special Pump inside your Chainsaw Carburetor, and any malfunction of the pump and can cause a whole host of problems (bog, incorrect running and starting issues, to name just some). Powered by the fuel pump diaphragm, this pump is the heart of the 2 stroke chainsaw carburetor.
In the passed I have found lean fueling to be a common cause of two stroke engine damage. Whether it is a chainsaw, hedge trimmer, 2 stroke rotivator, snow blower, leaf blower or brush cutter etc, this can be a common cause of engine damage.

A two stroke engine rev's higher the more Lean the fuel gets, up to a point! I explain what Lean Fuel means and why the engine RPM increases the more Lean the fuel to air mixture gets. Basically, it's all to do with combustion efficiency.
So, whether it be a Stihl 2 Stroke, or most other types of two stroke internal combustion engine, this principle will apply. There is, of course, a huge difference between Petrol and Diesel Engines and the way they function, so this does not apply to diesel Engines, nor 2 Stroke Diesel engines.
I had to repair a husqvarna 345 Chainsaw quite recently, which had damaged due to Lean Fuel issues. The piston and pot were completely un-serviceable. Your machines are basically on their own version of Private Health Care, and Individual Health Care at that, which can cost £££.
Whilst they are not exactly a range rover vogue svr, or something as fancy, they often do have lots of value, and we can all do without expensive repair bills. So it's always best to take care of your machinery.
When I looked down the list of videos I have in my youtube studio, I realized that I hadn't yet explained this particular topic. So, here it is!
