does anyone have a pick of ms390 switch ?

I seem to of bent the metal contact inside my ms390 and now the on off choke switch does not function properly. Thinking it may be easier to ask spud to work his magic.

The spring looking thing you mean?

They are only literally a couple of quid to buy and 2 minutes to replace as they just push in place.

Thanks for that. I have never seen that site before looks good for lots of other stuff like the annoying fuel caps that wear out. Feel an order coming on.

They are good and fast delivery if whatever you order is in stock, if not you normally get it in a week which is still quicker than my local dealer.

Pays to order a few things at a time, i always do. Sounds like it maybe worth replacing the fuel line in the 390 to, thats my bet.

I have stripped the carb and found no problems. I did a search on here and some one had exactly the same problem back in January. I am thinking along the lines of a new saw as the 39 was used when I got it and its done 5 years 10 hours a week so had my monies worth.

I assume you have tried changing the carb settings?

Have you checked the plug to ensure its a lean condition?

 

Unfortunatly there could several possibilitys, low compression. bad inpulse and split manifold to name a few but usually the fuel line goes soft and collapses first on them.

 

Give me a shout if oyu do want to get rid of it.

I cant remember what was checked as it stopped about 6 months ago. I would of started with the obvious and worked through new plug clean air filter check spark and then onto strip carb which looked spotless. I can remember not having the right carb kit so may need to order one. What surprised me was how it was fine for years then instant problem not a gradual loss of power. Sounds like it could be the rubber fuel line.
