Good-day all. My scruffy F6 mechanical renovation is nearing completion and I’m looking forward to driving it on the road for the first time.
Pictures of other 28IF's I’ve seen show 2 brass discs whereas mine only has one. Am I missing one, and does it matter? you'll spot that the +/- 5mm brass tube for the dizzy vacuum is also missing but I’m searching for one of those.
I’m not sure if my fuel pump is producing excessive pressure but as a precaution I’ll fit an extra gasket on top of the diaphragm . One contributor (who’s post I cannot find) added a piece of thin bore metal tubing to the fuel line to further reduce pump pressure. Any advice or experience of this?
The fuel inlet valve (controlled by the float) in the carb flops about and is not backed by a spring. It just flops in when you invert the carb. Should it be spring loaded?
Lastly, I saw Petak’s post from sowing a 28IF repair kit on Alibaba. I haven’t searched to see if its still available but has anyone tried it?
The Air Screw was 13 turns out. My van hasn’t seen the road for a few years but the engine starts and runs but I’ll turn it in progressively to find a happy medium.
Solutions or advice gratefully received!
