Czech amal TT

Not only a copy, but what looks like a very robust version.  The engineering in eastern European countries has always been inspiring.  I had the pleasure of a Tatra 87 when based in  the Netherlands some years ago, full of smart ideas.  Necessity; the mother of invention...

 Preserve it Thomas it looks a fine piece of engineering...

Cheers

That’s not been copied by the big japs much has it!,,  still using the enriching device on the side of the carbs.  And a left hand wrist grip….?

 The brakes are a work of art with pocketed spokes and effectively vented rear drum. What a screamer  that must have been.  Don’t tell me that’s in the shed Thomas….

great picture!,

If you look at the pictures, the jet holder is off-set to the side of the carburetor. The needle passes down the side of the throttle slide.  That is characteristic of the AMAL GP carburetor, but not the TT.  From the look of it, it's a copy of the GP, not the GP2, which had a different pilot mixture arrangement based on the Monobloc.

Hi All,

   The photo of the works Jawa looks to be a mirror image, as the front brake lever is also on the left in the photo. If so, the carb and float will be the other way round. The remote needle was also used on the Amal RN in the late 1930s.

You can see where the closed the central hole in the jet block casting. I’m not familiar with remote needle Amal’s.  I always thought the needle was truly remote to the throttle body similar to the enrichment device on the right side.

Thanks

Jon

Hi Jon/all,

   Yes, that is correct with the needle connected to the slide by a short bar whicn means there is a slot that runs half-way down the body for the bar to run in.

If the image was reversed wouldn’t JAWA on the tank be reversed too?

Hi Dan,

   Yes, well spotted. I was looking at the mechanicals rather than the obvious. Whoops !
