Stihl 044

[philipsmith]

Please can anyone help.....

 

My Stihl 044 will not start, changed coil HT lead and plug, good strong spark, changed carb all fuel lines clear compression seems ok. When I rest plug near plug hole port and pull the swaw over flame comes out, so fuel seems to be getting in. However when I refit plug and pull saw over and remove plug for inspection it seems dry. Can't think of anything else and fed up with spending more money on this saw.

If you have spark and fuel then do you have compression? Personally I would pull the muffler and look at the front of the piston and inspect for scoring,if this looks OK then I would take a look at the fast idle start throttle mechanism - this should kick the throttle valve plate open around 2-3mm, If this isnt happening, starting the saw will be a bitch!

 

If the piston face is clean, pull the plug out, turn the saw upside down, pull the saw over fast to get rid of pudled fuel in the crankcase, dry the plug -preferably with a torch and then take the choke off and get someone to hold the throttle open whilst you pull the saw over - avoid using the decomp valve to increase comp while doing this. If there is no puddled fuel in the crankcase then do the above with the choke on!

 

If you get stuck, PM me - if the saw has been seized then I may be able to save the cylinder.
