Ariel is a 1950 VG which came fitted with a 1&1/16 Amal 276.........I have lots of bits of smaller 276s ,and boring a worn 15/16 carb seems to be the best way .........the carb is also needing the body sleeved ,and the slide and guide  also sleeved or built up, all due to wear ..........might as well do the lot in one go.

 Im about to bore out a 276 carb to 1& 1/16  for my Ariel .........question is ,can I simply bore out the jet block/slide guide assy as one piece ? ....or do I have to unsolder the lower part ,so that the short tube on the jetblock is unchanged ?...........Unsoldering/resoldering could be tricky so as not to block  or obstruct any of the passages or jets...............I see lots of horribly bodged Amals about,seemingly enlarged with  coarse sandpaper wrapped around a stick,but they are never attached to engines ..............which Id assume is because they dont work anymore.

Hi!
I have a Tempo Sachs Transporter 125/175cc and I'm having trouble with the third gear. When I shift from second to third gear or from fourth to third, this happens: the gear pops out and goes into neutral, causing the engine to rev freely. When I'm riding, it keeps jumping out of third gear. I've tried replacing all the gears and bearings with new parts. The gear selector seems to be in order. I've consulted several mechanics who are familiar with these types of engines. They have opened the gearbox and confirmed that everything is correctly assembled and looks normal. We're stuck and struggling to figure out the problem. Has anyone experienced similar issues or have any suggestions on what it might be?

All made in China .........except Lucas trade mark is used by Bosch and all Lucas 'genuine'' parts are called 'legacy' and made in India by Bosch......Lucas is actually owned by USA conglomerate TRW Inc.

Worth bearing in mind that Renolds chain is crap these days and not a patch on how it used to be.
