Just an update, tried above and adjusted the contacts and just for good measure i opened the trigger hole a little further for more travel, it all fires beautifully again. Guys thank you for all the help.
Guys thanks for the help, it was all invaluable i went through all the things you suggested and I think samurai and bright candle maybe right, tinkered about today with the gearbox and I have found that when the grip casing is on it restricts trigger movement but if I push the trigger to the right it fires perfectly, when released it wont fire. I think I am going to be looking at the casing with a file and opening the gearbox again to check those plates out for a better connection.
Really appreciate all your wisdom and I will let you know how it works out.
