Hello all.
I spend a lot of time on this site looking for info, but don't often post. However, yesterday I was walking down a high street past a skip full of junk and a Johnny 49xp leapt out from under some old plasterboard, scrabbled desperately up the side and shouted for help. When I glanced at it , it said "take me home or I've had it", so I did.
Well it was obviously a non starter. But today it has been a very wet day indeed here. Someone else had had the muffler off, piston has some serious scores and no muffler. But Johnny was in the way, so I took the bar off, 20'' .625...very useable, and gave the clutch a good shifting up & down and back to front.. no play, starter off, same that side. As it happens, I have one of these already, so I know it was good in its day, but now too heavy and awkward.
This one will never be a thing of beauty, or desire. But you know, it's got to run. What has let it down was being run till it stopped with no air filter gauze.
Three questions only really. As it has to be fixed up for as little as possible, and barrel is v good. Would you use a piston again having cleaned it up so no protruding metal (ring groove is good) replace intact old ring ?....or fit the budget'est of budget pistons (£19) ? Has anyone found either a screen from another saw, a filter assembly from another saw, or material to make another screen from, or any alternatives ? Sadly, also it's recoil starter perforated screen is also missing, I am unlikely to find one of those in UK. Other than that.... It appears to be ready to go to work , even has fuel and a good spark.
I notice that the two case halves are not perfectly flush to sit barrell down on, causing base gasket to be cut, or nearly, at front on join. Can I afford a slightly thicker gasket paper, or do I risk slacking off case bolts as I tighten it down, or do I go for a sealant only job (Impulse corridor may become blocked) ?
I am sure some will think I must be insane, but I know there are others here who are worse, and besides, you lot started it !
