Well it would depend on what is wrong with it as to how long you want to spend on it.I understand where your coming from there.(It's like I have just picked up a Victa 4 stroke.Now somebody has painted with an oil based paint with brush.Now it won't run,so I have to work out how much I can get for it,then work out how long to get the paint looking right,how long to get it running and then take that from what it's worth (carry the 1).I can see that this one may not be worth the time and effort).So back to yours so yes I know exactly what you mean,however there is the fun and the learning more about them to consider.You should be able to find another hose,I just don't know if you could find a new one any-more.I don't think you would spend that long fixing it though,you could change the whole ignition over in much less time than that.At the end of the day I guess it depends on whether you want to do.That's the more important question.I know you'll work it out.
