Potash123 26 #1 Posted August 17, 2018 I am trying to service a 52 cc Plantiflex Chainsaw ( I think it is Chinese ). This model does not have a bulb primer ? It is not starting very well. I have just cleaned the petrol pick up filter which was a bit silted up probably with two stroke oil. I am trying to work out how the fuel gets into the carb without a primer as the fuel tank seems to be below the level of the carb. Help me understand please. Thanks.

Anglo Traction 1,016 #2 Posted August 17, 2018 I have never seen one of those, so have no idea what one looks like. Can only suggest you look at the Poulan Chainsaw Thread in Other Garden Machines and compare my images with your carb. Usually, if there is no primer bulb, then it primes/supplies fuel using a vacuum diaphragm system in the carb. Share this post Link to post Share on other sites
Wristpin 400 #3 Posted August 18, 2018 Possibly has a pulse tube from the crankcase. 1 HeadExam reacted to this Share this post Link to post Share on other sites
HeadExam 1,783 #4 Posted August 18, 2018 Most modern saws use a pulse tube from the internal engine pressure to supply fuel. Cracked or rotted lines can reduce the flow and cause low flow problems Share this post Link to post Share on other sites

HeadExam 1,783 #6 Posted August 19, 2018 BTW, you may be able to use the Husqvarna 455 as a reference to the engineering, they look very similar Husqvarna_455E_Rancher II_IPL_2018-02.pdf Share this post Link to post Share on other sites
