Go to your local small engine repair shop and buy 1 foot of rubber, not plastic, fuel line, just larger than the hole. Cut the line on a diagonal and insert it from the bottom of the tank. You will need a long pair of needle nose pliers to fish it up from the filler cap. Leave about an inch in the tank.

You probably need to replace the coil.

where (how) do I order a new coil for a 780r trimmer??

Hello kenroy100,

Ryobi has a module (coil) available for a number of the 780R trimmers. A few of them are no longer available however. To see if yours is still available you will need the series number of that particular unit. That number is located on the the same white tag that the bar code is on. If you can find that number match it up with your model number. Then locate the correct parts diagram to see if that module is still available.

Good luck,

Hi Ken,

Removal of the clutch drum isn't too hard of a project at all if you know a few tricks first. We have prepared an article and video that will provide you with all of the information you will need to remove the clutch drum. You can find the article and video at the following link...

Ok this is my first time attempting to repair my weedeater. I got to the part of binding the cylinder, but I have no pull rope. That's my problem, trying to replace the starter rope. How do I do this? Thank you and GOD BLESS.

Hi Rick,

The shaft is sold as part of the Upper Drive Shaft Housing Assembly. It is part #791-147486 and is available from http://www.ereplacementparts.com.

I hope this helps with your repair!

Hi Bill,

There is a screw at the bottom of the hole on the clutch drum. Removal of the clutch drum isn't too hard of a project at all if you know a few tricks first. The drum is held in place by a screw at the base of the hole on the end of the clutch drum. I believe your model of trimmer will require a Torx #T-25 driver to remove the screw but it could be a hex drive or Phillips as well. The screw will remove with a counter-clockwise rotation. When you try to rotate the screw the engine will likely rotate as well. Here is where a trick comes in. Remove the spark plug from the engine. Now find a piece of small rope, like an old shoe lace. Put the rope down in the hole for the spark plug. Be sure to leave enough of the rope hanging out of the hole so you can remove it later. The rope will bind up the piston so the engine can no longer rotate and now you can easily remove the clutch drum screw.

Good luck with your repair!
