Front wheel touches floor when folded

[straas]

I'm guessing this isn't normal?

If I'm in the supermarket I have to tilt the bike onto its rollers to move it - if I try and move it when it's flat the front wheel skids along the ground.

What should I look at tightening?

What is the bike ?

Oh yes sorry, this is a Brompton M6L

The front wheel should just hover over the floor when folded, on the older Bromptons the clip that secures the fork to the frame when folded is mild steel so can easily be bent slightly for adjustment, I’m not sure of the later ones can be moved.

My solution was to stick a piece of a rubber (eraser) to the underside of the frame, seen in this image:

When folded it rests on the back wheel, lifting the front slightly.
There is an offset plastic disc attached to the rack that rests against the seat tube when folded - I had to rotate that a bit to allow the seat tube to fully drop.
My Brompton is a T5 - do later models have (slightly) different geometry?

"gomme" I think.
I get a mental picture of the classroom where I learnt that word - in 1971 probably.

Just got round to taking some photos! Not sure how clear they are or if I should be taking photos of different bits?
