Vintage Tractor Engineer asked Neil if this was the only alteration that was made to the engine – was everything else just as before. Was this the only alteration to the engine? My tractor now starts satisfactory (no easy start!). The experimental data was obtained from a 4-cylinder Cooper GMV-4TF large bore. This is distinct from manifold injection systems, which inject fuel into the intake manifold (inlet manifold). Precombustion chambers (PCCs) are an ignition technology for large bore. I contacted John at Park Engineering, he could not have been more helpful, the work was carried out whilst I waited. Gasoline direct injection ( GDI ), also known as petrol direct injection ( PDI ), 1 is a mixture formation system for internal combustion engines that run on gasoline (petrol), where fuel is injected into the combustion chamber. You made me aware of two companies who are experienced in this procedure, one in Ireland and Park Engineering, North Yorkshire. Working back to front I had overhauled the engine, experienced difficult starting, then purchased your DVD, which confirmed I had done most things correctly except I was not aware of the need to enlarge the combustion chambers.

You may recall I emailed you earlier this month regarding difficult starting of my 23c engine. The grinding was done while Neil waited and then the engine was re-assembled as before.

Neil removed the cylinder head, loaded it up and took it along to Park Engineers (that’s who Vintage Tractor Engineer uses, and John at Parks knows his job inside out). Neil ordered Vintage Tractor Engineers’s DVD so see if there was anything he had overlooked, and the only thing hd could see different to his own job was that the engine in the DVD had had the entrance to the pre-combustion chambers enlarged. One of our fellow FE35 owners (Neil) had completed a full rebuild of his engine but the starting performance was disappointing. We have written before about the benefits of enlarging the entrance to the pre-combustion chamber on the Standard 23C engine as fitted to the Ferguson FE35 tractor.
