I have TROUBLE getting my carb jobs to fire back up ?
« on: May 04, 2014, 11:03:58 pm »
Like in the title.....I suffer trying to get these units to pop off after doing a carb job.... my carb jobs are not shade tree by any means.... I just can't put my finger on some units ? ...One unit I had to back off the low needle to almost 2- 1/2 rounds to pop off and once it was all said and done....the low was back to 1 or so and the saw ran great... I am missing something on the Poulan saws ? The last few were PP220,Pp260,2025.

 >:( 

Thanks for any tips Guy's,

Phil

No...the Walbro kit's do not have the spring...so..I use the original...if I ever drop one ...I will get a OEM walbro spring based on the stencil number ?

Thanks,
Phil

I just prime the carbs sometimes to get them going.    It just takes to much pulling on the rope.

I use a syringe with fuel in it and squirt a little straight into the carb.   I hold it at WOT and then pull the rope.
The few seconds the engine runs at high RPM's has a lot more pumping action on the diaphragm in the carb than I can achieve by yanking on the rope.   I may have to do this a couple of times and then it will work on its own.

Well...I don't have a medical syringe ...but use a very small sqeuzze bottle of gun oil, no gun oil left of course.... filled with high octane non-eth fuel mix...but hey....the syringe might do the trick !....and yes...my old neck and shoulder is only good for about 5 quick jerks ! The machines that give me that trouble ARE getting fuel to the plug....compression always checkwith gauge...spark check with inline tester...I think I,m going to just by a NEW carb for one of them to just say I did ?

A new carb will be dry just like the ones you rebuild, so the process will be the same. I have been known to soak the new carburetor diaphragms and gaskets in a kitty food can with some pre mix in it. I put the new parts in the fuel when I start to take the carb apart and by the time I an ready to reassemble the carb the new parts are nice and soft. Try it, it works for me more often than not.

Eye droppers work well for priming as well.
