After my blaster blew up on me two days ago I took it apart and today I noticed that the crankshaft is scratched. A piece of the piston or something much have gotten down in there. The rod goes between the two weights and it is scratched on the left weight or whatever that piece is. The scratches arent deep amd not the whole way around. I really dont see why it would matter, but sometimes these type of things have to be perfect. I cant really get any pictures of it. Could anyone give me a guess whether or not it will be alright or not? I am still going to call a dealer or someone and have them look at it, but I want to know kind of what to expect. I am getting a filter tomorrow and running my old oil through it to see if there are any metal peices in there. And I bought another quart to run through a bunch of times to try and get all the stuff out of there if there is any. ANY help is appreciated. Thanks in advance
