The pump got here today so hope to check it out this evening I have a feeling the seals are bad and not able to create a vacuum to suck the gas into the carb I do have a set of new seals here if needed and a tube of dirko... if you search stihl dirko on flea bay looks like you would pay $20 some dollars a tube for it but if you just search dirko you will see they also use it on VW's and it is half the price of what stihl sellers sell it for hope ot see this thing run this week end although the seal on the fly wheel side looks like a problem to get out
