Hello,
I have a jonsereds 49sp chainsaw for restoration.
It has good spark, good compression and a rebuilt carb. I also replaced the fuel lines. But for some reason the carb does not draw in fuel...
I am pretty sure the carb works fine. it's completely rebuild and holds its pressure good. But for some reason, if i pull the starter rope, the fuel does not travel up the fuel line. You can see it in the picture.
I removed the fuel filter in the tank, to make sure that that is not the problem. I tought that perhaps the tank vent line was the problem, so i removed that as well. But stil the fuel won't go up...
I also checked the hole between the intake manifold and the carb and it seems free as well...
Any ideas what could be the problem ? I have restored chainsaws before and always got them running, but this one is a real challenge... Not sure where to look next...
thanks !!
