Why does my saw die when hot?

Recommended Posts

MS210, starts and runs fine for 5 minutes or so and then seems to run out of fuel. Doesn't stop, just completely lacks power. If I keep trying to use it it will stall. Starts easy when hot and ticks over fine.

Sorry to ask such a boring question but could I have a check list of things to look at. It has fresh fuel and visually the filter in the tank looks fine.

My husky is a right prima donna in hot weather. Could be fuel evaporation in the lines. Lived inAustralia for a long time in the Northern Territory and had an old van with the same problem. It was unusable between 11am and 3 pm. It was proper hot there though. 40 degrees c plus. I’m sure this answer is of no help to you. I had a few rums after discovering I can’t work for at least three weeks due to Oriental Bat Flu Lockdown.

I’d plumb for full carb clean / new kit / reset metering arm when done as peatff suggests. Just check the impulse line too though, (crankcase to air intake) they can pop off or split causing a poor revs / stall scenario like you have.

If it restarts strait away then probably not low comp . Could be tank vent blocked causing a vacuum but most likely as others have said a carb problem . Metering arm height seems a good place to start .

My Stihl chainsaw did this, I stripped it down cleaned carb, bebuit, still the same. Changed the spark plug and it started working perfectly.

Spark plug must have been breaking down under load.

Ignition coil?

Apart from the above, it is always worth changing the fuel filter. I used to think changing them wasn't really important but have recently had a few trimmers and Kombis in that won't rev out and a new filter has resolved the issue so live and learn.

Sounds like it just needs a good going over as most machines only get it when they have issues like this.
