Roper 3.7 fuel line

[a. palmer jr.]

Haven't quite figured out the best way to put a fuel line in my 3.7 Craftsman/Roper chainsaw. It appears to be a two piece design or I may have pulled it in two when I removed the line from the carburetor. I tried running a piece of wire through the hole and it didn't come out the other side...help!

Mine looks similar, has a red starter housing and a black air filter cover but basically the same saw..mine has a hand guard on top bar. I found a parts list from Sears and it appears to have a two piece fuel line but it looks like you have to remove the tank to get to it if I read it right..

Remove clutch has left hand threads...remove the four black counter sunk bolts behind clutch ..unhook oil line in front of you .One bolt on the bottom of saw at the handle ..pull apart fuel line is there

Two peace line this is the only way to fix

Yeah, I thought it was like a Super XL but I sure was mistaken! Might as well do some cleaning on it while it's apart. I got rid of what was left of the automatic chain sharpener, it already had a regular chain on it anyway..

Two piece with fitting in tank.

Can't remember how i replaced it cause I had to split crankcase to reseal it.

Removed the fitting added each line one to tank then carb.

That's it in the corner, been about a year when I did the case, my memory isn't good anymore but that picture helped me remember. Thanks.

Wow, I learned a lot today! I didn't realize it was gonna be that big of a job but I'm gonna tear into it pretty soon. Thanks, guys!

Not all of them are threaded. Seems like I doubled tygon to make it work, and yes, they are a PITA. The carb links are finicky too. Need 5 hands to put back properly, 4 to do the job and 1 to hold the 5th.

I don't think my fuel line looks like that..I believe mine is a two piece and from what I've gathered I don't have to split the case but I do have to remove the tank..

I hit a snag. I'm having trouble getting the clutch off. I'm sure it is left hand thread like most saws but can't figure out a way to turn it. I tried putting a wooden piston stop in the exhaust and heating up the center of the clutch slightly but the darn thing will not turn. I also couldn't get a very good grip on the clutch to turn it, probably Roper people use a special tool...
I also tried some PB Blaster on it to no avail..

I had the same problem. From my other thread, I had to use a 1/2" impact to get the clutch off, never had one that bad. My 3/8 butterfly is a cheapo, but this is the first clutch it couldn't move. I ground a socket to fit it. Then, I had to use and impact screwdriver to loosen the countersunk screws behind the clutch.

In case you are questioning yourself, mine was left hand thread.

 

[a. palmer jr.]

Where did you hook the socket to the clutch? I didn't notice any place on the face of the clutch that would hold up to an impact wrench. Oh, I think I see it now, there's just two things sticking out on your socket? I was looking for 4 I guess.
