Alan, I have had 4 or 5 different injectors from blackgates over a period of about 6 years, but none for 2 years now and none of them worked. Modelworks seem to use the same part for their kits as everything is identical and theirs does not work also. I have been able to modify one to work occaisionaly but that is all. I have had 3 from Bruce Engineering and all worked first time and continued to for about 18 months then no matter what they will not work again. I am on the lookout for a reliable one for 5" and 7 1/4" gauge at the moment. I know one of our club members bought one from Blackgates last month and had no sucess with it. I am waiting to see how he got on with a return. Garry MODEL ENGINEERING DISCUSSION LIST.
