Question about Roybi weed eater's line length.

U sure about that? Never come across a weed eater that was not of the bump kind!

Here is a video I found helpful.

My roybi did the same thing. The fuel lines were swollen due to the ethanol in the gas. Replaced lines with ones that can handle modern fuel.

I work with weed eaters and mowers. Weed eater fuel ratio is normally a 40:1 ratio. That usually all weed eaters fuel ratio.

If it was just bought new I would take it back and let them deal with it.

Unscrew thw bump nut to remove the spool. Take a length of about 6 foot of line, kink it in the middle and pass this through the hole in the spool. Wind the two lengths of line around the spool in their own divisions and in the same direction. The direction of wind is embossed in the reel and the line should be wound tightly and held all the while. When you have about 6-8 inches left in your hand, bring the cover up to the spool and carefully pass the two ends of the line through the holes, push the cover all the way over while pulling on the two pieces of line and ensuring that the lines stay on their own side of the division on the spool. Fit and tighten the bump nut and trim the lines to just about the cut-off blade.
The lines should trail out of the holes in the direction of the machine's rotation. Try cut with the tip of the line as much as possible. Cutting nearer the drum flexes the line and will lead to early breaking of the lines. Run the motor at a constant speed and rather move the cutting head in and out of the weeds to affect a deeper cut

Sounds like the clutch has taken a long trip south. If the clutch pads are not wore out, try some wd40 on the pad hinges.

SOUNDS LIKE YOU MAY NEED TO REPLACE THE FULE LINES THAY DO GET BAD OVER TIME

I have a ryobi doule line bought in 1997..Had same problem put new gas cap on and problem solved..could not get air in....

I believe there are four phillips headed bolts around the outside edge of the housing
