Nurse Julie:
I lapped in the valves this afternoon. Had never done it before so had to have a Tutorial from Trig. Took me ages to do but got there in the end.

I hate doing that job especially when the poxy rubbers won't stay stuck to the valve 😡😡
Did get a good tip that does work tried it last time, self adhesive Velcro cut to the size of the rubber and the valve👍👍👍

Johnwebley:
You could use a  small piece of fueltubing on the valve stem.to help twist.also pull the head on the seat.

Hi Julie,

Reading your update with interest (after a long lay-off the site).

I'm a big velcro fan (for all the right reasons!) and you've just given me a new right reason. Wish I'd read that before I struggled with my sink plunger-style lapper-in tool!

Keep up the good winter work.

Nurse Julie:
I actually just did it the 'normal' way, rubber on the valve. It took me a very, very long time to get them as perfect as I could. And yes, the bloody thing kept slipping off and my hands are quite sore now. Reminded me of trying to start a fire with a stick in a hole 😁😁😁
