Questionable start - Stihl Ms170

[Dacha]

Update. Just when i was putting it all together, i realized that have trashed choke rod.

Will have to continue testing tomorrow once i get the new choke rod. Oh, well.

But everything looks nice and clean now.

I am trying all the plastic pieces to line up, they kinda line up but not perfectly. Once i try it few more times it just may click into place.

i did some cutting yesterday and stihl ms170 served me well once it started.

it took 20 pulls to start it. Storage and outside temperature was in 20s and 30s.

i have it for 3 years. First 6 months from new was starting poorly, like 20 pulls.

than i decided to drop warranty and took whole thing apart and cleaned it, replaced only spark plug. Since then saw was starting almost for 3 yrs on 3rd pull. In both hot and cold.

I kind of feel i now all possible routes to deal with it, but thought i would consult the forum.

I will try replacing the spark plug first.

Will replace air filter too.

If can find a dealer that can measure compression, will do that too.

Will buy new gas mix, but am sure gas is not the issue.

Sure i can pull out spark plug and warm it and than put it back, before cold start, but would like to have cahinsaw ready like it was before.

Chainsaw has around 40 working hours on it. Someone mentioned that these are 40 hours saws.

Any suggestions welcome.

My late and much lamented mate referred to my Stihl as "That cold-natured biotch". Then the city changed the work saws to Huskies, and he *really* hassled me about it.

Chainsaw is starting cold as should again.
