Hi MW,
unfortunately the spare length of line was pretty much the exact length required for the two pieces going into the tank, the one for the fuel draw had about a cm to spare. I did cut both to a point shape but the grommet fell into the tank as I tried pushing it through with pliers.
Making the best of the situation, I tried pushing the lines through the grommet while it was out but they just wouldn't, so I thought up the idea of using a length of coathanger wire into the line and then gripping it with pliers and wrestling it through gradually. It was painstakingly slow but I got there on the end.
It was a pig pushing the grommet back on, having to resort to trying to hammer it back in with a length of brass rod. Part of the rubber tore off the edge, but this served to allow me to finally push it in.
I happened to have a spare intake filter end for the fuel line so replaced the mangy looking original one.
The machine fired up but still displayed the hesitant behavior when I went to rev it, so I turned out the auxiliary high speed adjusting screw ¼ out and that did the trick and now it runs well. The idle needed some fine adjustments as it went to stall at one time.
I trimmed my front patio and a bit of the rear with flying colours.
The manual change head says 3mm only but only had 2.5mm line and it worked well. Will I wear out the alloy using undersize line?
