Hello again fellas couple weeks ago you guys helped me get my 3300 going again. Well I have no good reason but I just purchased another 3300. Usually in past I get a saw I always without checking would just put new crank seals in whether Stihl echo poulan whatever. And so far it has served me well never had a problem. My question is this 3300 looks good but is around 30 years old , should I put seals in as good insurance or not worry? If so is the correct part number 530019146 or is that the little oil pump seal? Thanks in advance
