New piston and ring have been fitted thanks Jin,only problem is the engine is seizing up after about 20 seconds.
The new piston has been oiled and turns freely have tried the old one and it does the same,when it stops both flywheels are loose on the crank.
Has anyone any ideas what's causing the engine to seize and how to cure it .
Thanks Trevor.
ps hope everyones bearing up under the present conditions.
