Sounds like a bad design to me. Is it? being serious here.
Now if you need someone to adopt 1 of your 260's I might know of a loving home that could nurse it back to health and keep it busy
It's an old saw...rear cylinder, tanks up front, etc..
The carb is on top in the back, fuel line runs into a barrier about halfway up the case, and into the plastic fuel tank after about 1" of empty space.
You obviously have to remove the recoil, flywheel, ignition, rear handle and controls, A/V parts, then remove the screws thar hold the case together. Remove the carb, intake spacer, gaslets, etc..
A few taps and alot of luck, the case splits. The crankshaft rides on bearings in the case, there isnt a "block". The cylinder bolts too the case. Also you have to unbolt, but not remove the cylinder.
Then you remove the fuel tank, make up some line that fits, because the hole in the tank is 1/4" and needs a special grommet that is NLA..so you oil up some small line, run it through a sleeve of some larger line, and put it into the hole in the tank, put on a filter, and start putting it back together. However, there is the matter that the crankcase is surrounded by the oil resevoir. The case halves actually form the oil resevoir. The barriers that meet at the center of the case halves are about 1/16" thick, and Id say, totalled about 3 feet of them that go around the perimiter of the case halves, around the crankcase section, oil resevoir section, fuel tank section, etc...and they all hav to be perfectly clean or it wont work. I scraped it all clean with a razor, and the gasket is NLA, so I used some "the right stuff" and put it on there, put it all back together, ran my line to the carb, added fresh oil to the resevoir, added fresh mix to the tank, and after a frw tense moments it popped. Choke in, pulled and it fired up and ran good. I tuned it in a little, ran better than it ever has. Also, no smoke means the oil resevoir isnt leaking into the crankcase...no leaks means I did good.
Still runs great...
Although on its first outing after the repair I discovered the new bar I put on it was broken. The thing would cut so good until it gout about an inch into the log, then it would just stop cutting completely. Took a few minutes, but the bar was splitting in the center.
New bar and OMG...it cuts great.
Bad design? I dont think so..the fuel line is very protected this way, the old line lasted a very long time. Could it have been done better? I think so.
I could do it faster now..the first time is always the most difficult.
