Getting my saw in half?

Hi folks

 

I need to get my saw in half, so I can replace a broken fuel line from primer bulb to tank (roughly following green line on pic below). But I can't get access to it as I can't get the saw into two pieces - I want to get the handle and fuel tank assembly off the engine and main body of the saw (at the red line on the pic below) so I can get at the fuel pipe. I've undone everything I can find - the trigger linkage is still in place, but that's not the issue. Somewhere there's a bolt or something holding the two sections together (though they wiggle and flex). I've not taken the clutch off - I don't have pullers or anything and think that might be beyond my skill anyway! But presumably there's nothing holding the two bits together under the clutch?

 

Am I an idiot? Am I missing a bolt under all the saw dust or something? (It's a cheap Chinese saw, badged Spear & Jackson, but it's served me well for 10 or more years and I'd like to fix it if it's not too much of a faff...)

 

Thanks.

Thanks OSM, that's handy. Looks like there may be a hidden bolt at 60 I've not managed to get. Maybe. Maybe I'll just buy a new battery saw!

 

As for the airline, you're right! I'm not a commercial user, domestic only, but it could do with a clean while I'm there :)

You don't need to split any machine I have come across to remove the fuel line. Typically clean the carb area and then remove the carb (if needed) and replacing the line should be relatively easy. The manufacturer usually allows you to change the fuel line without taking the rear handle off.

Thanks spud. I did try getting the carb out, but it seems to be attached to the engine via some sort of solid gasket? I undid the screws I could find and the carb didn't shift a milimetre. Will clean the crap off and have a closer look tomorrow. 

Also, the fuel line seems to run right down under the carb into the tank, pinched between handle and back of the engine, and I'm not sure if would be possible to access it without taking the handle and tank off? (This is the first chainsaw I've tried to dismantle and I may be missing something obvious...)

Been looking at that IPL and it looks like the fuel lines push through a large grommet, I am thinking that once the carb is off, that grommet will be under it or there will be a removable plate under the carb as on many Husqvarnas and that should give you access to the fuel line. 

I can't see a removable plate but I can't see anyone would have to remove the fuel tank/rear handle assembly to change a fuel line.

The primer should connect to the carb on one line and the other one just pushes through the grommet to return the fuel to the tank.

I cant 100% remember but i did the fuel lines on one of these saws, there are hundreds of variants out there in different branding and im pretty sure i had to remove the handle to get at the grommet that holds the fuel pipes. On re assemble the oil pipe never fitted back properly and it pissed oil out all the time. Got sick of seeing the thing eventually and threw it in the skip.

Got the carb off, and there's a plastic plate under it, part of the body of the saw and not removeable. Having said that, I seem to need to replace the other fuel line, not the one that goes right down to the base of the handle but the one that goes through a grommet under the carb, and that I can just about get to now. To be continued!

I've got screws and plastic bits all over the garage, and not sure I'll ever get it back together and working! Skip is always an option, but I'll try a bit longer before I give up and buy a new saw...
