    A guy I know is giving two old pb-400 blowers. If there isn't too much wrong on them, Is it usually cost effective to fix them? (In other words, would I be better off buying a new one or fixing this one.) And what would be a ballark guess on cost to rebuild one of these? Is it something I could do? When I get these I am hoping it is simple stuff since he isn't much of a mechanic. He can't remember why he quit using them, but i am guessing something simple like a muffler or similar. I don't think he used them enough to wear them out. I will give more information when I get these. Thanks for the help, Snapper
     
  2. If they are free why not take a shot at fixing them. Most 2 stroke problems are, fuel, carbon, carb.-easy stuff & cheap to fix---
    If its more than that decide if your time and parts $ are worth it.
    If nothing else I'd take them to mess with in off season

    Okay, he gave me three of them. On of them is defineately a parts blower; One of them I got to run, but has a loud clank/knock , it seems to have full power; and one I haven't tried yet. I will post what I find about the knock. Any guesses to the cause of the knock? Thanks, snapper

    Well I figured out the knock. The knock was dirt or some thing in the fan houseing. I cleaned out the chamber and put it back together, no more knock. This isn't the most powerful blower, but defineately a step up over my old one. If anybody has any tips or tricks to using a bp blower, I need them. Thank you Snapper

    Right now only one is running. The other two, one is missing pull rope, carb, spark plug wire,etc.., The other one I can't get fire out of the plug, so if I can get it to fire, it might start. Some day i will work on it and see. Now, for a new question. When this blower wears out internally(which i'm guessing will be a while), what is involved in rebuilding it? It is difficult or require special tools? Can you buy some kind of short block? And what kind of a price am I looking at for parts?(in other words, does it cost less to rebuild or buy a new one) Thanks again, Snapper
     
  7. Rebuilding these engines is simple. Parts are not that $, so your labor is the big thing.

    for parts prices check this site- they are a little slow so dont be in a hurry to get things but they have a great search site.

    by not getting "fire" are you not getting a spark?, probably electrical if so , check all your switches

    what it is on this blower, there is an internal thing inside that makes the voltage, a single wire runs out. Then you have the spark wire with a thing on the bottom where the one wire goes. I think this might be bad. When I get around to working on it I can pull the one off the working blower and see if the other blower will fire. If it does I just need one of those, if not it's the internal thing. But right now I got one running and thats all i need. Even if I get spark, I don't know what kind of shape the seals, rings, carb,etc.. are in so it might run or it might not. New question, typically when rebuilding a 2 cycle what parts do you replace? Is a short block neccessary, or can you just do seals and rings and such? I have never rebuilt one so I was just wondering. Thanks again, snapper.. forget to mention, They are pb-400E. I dont know what difference the E makes but it does.
