Went to get a load of wood and saw would not start. Got it to run for 10 seconds with a big puff of white smoke. Plug was wet. Gas should be good same tank i already burnt the rest previously. where to start?
When you try starting it, did you try setting the choke and then turn the choke off without touching the trigger (half choke) then try it?I really like my ms250 - but there is the very odd time that it drives me a little nuts not wanting to start hot. I will cut away for a while, have to stop to move some stuff for something so shut it off, and 2-3 minutes later it won't start no matter how much I pull & what I do with the choke & throttle. Seems like it floods itself, but cranking with it all opened up usually doesn't work either - so don't know if it's that or it vapour locks somehow. It doesn't happen very often at all but it sure bugs me when it does. Fires right up after it cools right off. So now I usually just leave it idling, or grab another saw if it happens. Never put any effort into trying to troubleshoot it. Maybe I should check the plug out - don't think I've ever replaced it.
BTW on stabilizer - most mixing oils have it in there already. I use the orange bottle Stihl stuff and usually don't have any issues with my 2 stroke stuff gumming up. But when it does, that Seafoam stuff is like magic. Cleaned my old weedwhacker right up after spending too many summers up high on a shelf in a hot shed, after running one tank of gas through it with the magic juice added. It cleaned my splitter with a GC 160 on it up after a tank through this summer too after it started spitting & sputtering after sitting a couple months.
Not sure. I think. Usually worked my way down the settings, cranking a bunch between each. Choke on was last try. Then holding trigger wide open with choke off if i had any oomph left in me.When you try starting it, did you try setting the choke and then turn the choke off without touching the trigger (half choke) then try it?
