Hi
I am new to the site and vintage engines. The problem i have with my Rosebery 3c is that after starting the engine and letting it warm up when i try to switch it over to kero it will not run. Its like it cant pick up the fuel out of the tank as it runs very well on the small hopper that you put the petrol in. Hoping someone might have an idea of the problem. I have checked the small check valve in the fuel line and it seems to be ok. If i apply a small amount of air into the tank it will run fine until you stop the air flow. I hope this post dose not sound to silly. Thanks.
