Flames

[Forest2Furniture]

I've been milling today and a few times as I switched the saw off at the end of a cut, flames came out of the exhaust.

 

Can anyone explain why this may happen?

 

Thanks

Build up of unburnt fuel in the exhaust maybe.

 

What saw. Does it run ok.

2 yr old me880, runs fine, starts ok. Just started this problem today and not all the time

to save your saw when milling, do not turn your saw off until it has cooled to normal working temps, just leave idiling for a few more minutes.

Spot on!

Thats the special built in cigarette lighting feature, an optional extra on the MS880 - it must be the delux version - I believe this can be retro fitted but only on a face to face basis:001_rolleyes:

 

Seriously - I think Rich is probably correct, you must have unburnt fuel build up in the exhaust which is igniting and causing the flames. It may be your machine is running a little rich but leaving the saw ideling for a while after use will let the saw clear the unburnt fuel vapour.

 

Worth checking the plug colour after a good run - if the central electrode is coffee colour all is well!

Thanks for your help, will try letting it idle for a while

when Im milling, especially on long runs, when I get to the end of the cant, I let the saw sit on idle for around a minute, then a couple of blips before I switch it off, Ive found this is the best option to guarentee a first or second pull start on the next run, dont be scared to stop, sit the saw down , and fill the cup at any time, gives the saw time to cool down and makes the job more enjoyable as well
