No signs of cracks? Good that it is painted and not powder coated.
Yes, it would have been nice if he showed the process from the beginning. It almost looks as though he has the ends just taped off, which doesn't make sense. Here is another fellow.... it shows the tube capped and a threaded packer in one end and it also gives a better view of the torch.A note on Mr Yoshimura's undisputed skill. In beginning of the clip, there is indication that ends of the pipe is plugged. With the big nozzle he has on the torch, the time it takes for him to get temperature up to when it is possible to bend the tube makes me believe that it's sand filled. It is very interesting to note how he moves the torch to get the tube soft in the right parts. His combination of feel when pushing on how the tube wants to go up or down and his adjusting on where to apply heat is simply amazing. Looked at that video before my little tube adjustment. Otherwise should not have fixed it. The video is a good example of a very good craftsman doing his work with simple tools.
Paragraph 3 in post 81?Emptied the fuel tank. According to my calculations, she used 1.5 miles per gallon! My guess today is that the problem is something with the float chamber.
Looks very nice. It inspires me to head out to the garage and do something with the shrapnel laying under the bench.Test start accomplished. It'a a lovely engine (thanks Molnar), really smooth. Only air in tyres and petrol in tank (not the opposite). It's a very easy starting machine. As an old racer explained it, compression ratio should be where it gives lot of power and is easy to start. In the old days when engine was off when the flag was dropped. Seems the float bowl change worked. Now load everything in the van. Practise on track sunday
......i have never seen copper floats ,brass is what you meant i am sure,
copper is red, brass is yellow ,that is an easy way for us to distinguish the diff
re sticking viton tips this is why the japs and others have a simple dangler hook at the spring loaded stem end
it serves to mechanically pull the valve open upon a bit of float drop
the hole size in the seat has 2 distincr effects
a larger hole offers more flow at any given float drop/opening but also needs more float pressure to shut the valve
spring loaded stem tips are very desirable
......yep those are all brass my color ref was regarding clean metal the brass turns brownish-red
i have in front of me now a dozen del's from early 60's on and even the remote bowl ss1 ss2 have brass floats
copper is too ,weak and would need be heavier than brass by a considerable amount to not be as fragile as a dry popcorn fart
