Echo SRM-2410 Brush Cutter - Fuel issue?

I have a 10 yr old SRM-2410 that has worked perfectly for me until last spring.

As I recall, if the tank was full it would start and run until the fuel level dropped... maybe less than 1/8th (7/8ths left in tank). I decided to live with it to get the spring work done and get to it during the summer. Didn't happen!

Anyway, now it wouldn't start. What I noticed is when I push the primer bulb it appears that no fuel is drawn up.

I looked at the bulb it appears to be fine. When I press it a few times no fuel comes up but I can see bubbles in the fuel tank each time I press the bulb. I don't know how this works but I'm thinking maybe the line is open somewhere?? I don't want to start digging into it before I have a bit of an idea what to look for.

Can anyone give me a few ideas to troubleshoot this issue.

Thanks,
Alex

Make sure the fuel lines are all good and that the fuel filter is still connected to the fuel line. If it is broken off the fuel line the screen inside carburetor is more than likely plugged. Good luck.

I thought if pressing the primer bulb causes bubbles in the fuel that indicated the line is intact. I will remove it all and check it.

That is not always true, you could have a cracked line down near the filter it's self. Good luck.

I think you will find the fuel line is broken off in the tank, when replacing the fuel line replace them all and save yourself some time. Have a good one. Geo

Well, you're right....I think.

I took the tank off and examined the three lines going into it.

The fuel line (blk) & filter were good...
The vent line (blk) was good.
The primer line (clear) was only about 3" long... barely in the tank. I didn't think that made sense. So, I broke down and spent $1.18 on a 12" of new tubing.
Cut it to size (10"), re-attached the tank and put a bit of fuel in it. When I pressed the primer bulb a couple ties I immedately knew things were good because it sucked fuel into the bulb and no bubbles appeared in the tank.

One pull and off she went!

So, all who said 'broken line' win.

I said 'I think' because I found NO broken piece of line in the tank.

I'm guessing that when I emptied the fuel tank (spring) it may have falllen out unseen.

Thanks to all!!

Now I'll look for some other stuff that needs repair

Not so fast. It picks up fuel from the line with the filter on it. If putting a longer line on the return (which is supposed to be short) makes it run, then your lines are not installed correctly on the carb. It is picking up through the un-filtered line and returning through the filter. This is going to clog your carburetor in short order and then you'll have to take it apart and deal with that. Switch the pickup and return lines on the carb.

Hmmmmm....

You can sure spoil a party.

I didn't think I removed the fuel line from the carb.
But I must have last Spring... for some reason or other.

I checked and you are right! I switched them and things are still running fine.

The primer bulb sucks fuel up and squirts it out the return.

Can only suspect I swapped them last spring and forgot about it.

Guess I won't be showing up for that small engine repair job...


Thanks much!

Great! Glad you got it fixed. Didn't mean to spoil the party but it's better than having to tear the carb apart next week.
