My neighbor has a Scott's model S2554 that turns over when starting byt when the electric choke switch is pulled the starting motor stops. this is the first time it has been used this year. I don't have a wiring diagram but it seems like the start circuit is controlled by the choke switch.

hi, my poulan 2375 wildthing chainsaw (approx 12 y old) will (eventually) start but does not keep running. Here's my trouble shooting overview: 1) Gas cap feels like it is being sucked in too tight.....tried to pull / push on the little "duckbill" on the inside of gap 2) Primer bulb does stay "collapsed" for a long time....comes back VERY slowly... Based on this I think I may have a problem getting gas to the carb.....hence it will not keep running after starting.. 3) I did check the gas lines ....only thing I noticed is that the fuel filter was not connected to the fuel line in the tank (when trying to reconnect : the fuel line keeps on splitting....| So I guess i need new fuel line,....but not sure if that can cause the "vacuum" problem.......any insight/ideas would be much appreciated..... (Yes i did clean the airfilter "sponge"...was very dirty.....brushed it off thoroughly....even tried running without airfilter: no luck!!) Please lmk yr ideas, WILLETTFARM
