Following on from other posts regarding Mikuni and DellOrto carbs, here's another alternative.

 

I have been building a D7 trials bike and had a new unused Jikov carb for a CZ 175, they cost £28 from JawaShop in Czech Republic.

 

Connected the fuel lines at the weekend and three kicks later it started and ticked over.

 

The CZ 175 is a similar slow revving two stroke so I thought it should work, bolted flanged connections as well, bolts straight onto a D10 barrel.

You've beat me to it, I've got a complete one somewhere and have often thought about fitting it to the D7 to see what might come of it. It's in good condition too, should be an improvement.

Yes that's it.

Don't know what the exchange rate is at the moment but about £30, takes just over a week for the parts to come from Czech Rep.

I also fitted a 35mm diameter clamp on air fiter for a pit bike - £5 from ebay

Problem though is, which one to choose? I had the rather bumptious idea that there were only one or two, at most.

There is a huge list that the carb is supposed to fit, but there is only one option when you order.

 

A CZ 175 has a 26mm carb, it came jetted for a 175 hence it didn't work too well on my CZ 125 but works fine on the D7.

I thought that was just an example? Was looking through the lists of course, but if it's the one, that makes it much much easier.

Are we going on venturi size alone here?

That carb has quite a good period look about it. Does it have a pilot circuit ?

Yes it idles away perfectly, it also has a ticker pin.

I should maybe have said that my D7 trials bike has a D10 engine in it, so I suppose it is a straight swap for a 26mm Amal

Iain, are you still happy with your carb from the Jawa shop? I'm rebuilding a B175 engine and considering replacing the old well worn Amal concentric, maybe buying a Mikuni, Amal or Wassel copy at Stafford. Then I saw this thread and thought "What a bargain, or is it?"

At 34 quid or so, this carb seems too good to be true. How was starting during those cold Aberdeen winter days - is there a choke on the carb? I'm not too bothered about originality and being a good Scot, I don't want to waste my money if I don't have to!

The D7 and B175 are different beasts, the B175 being more highly tuned with a bigger inlet port. I'd be surprised if a carb suited to the D7 performed as well on a B175.

Hi, I have a D10 engined B175 which has a B175 head on it may give one of these carbs a go as the Amal I have on it is quite worn. Regards Basil.

Having read some of the threads and posts about the d14 and b175 having higher compression than the d10 and that Amal recommend different specs for the d14 and b175 carbs, I think I will play safe and have a new Amal. Does anyone know what the difference is between the standard and premier range of Amals?

I believe the premier has the stay up float and Viton needle as standard. If you ring Amal and ask them they are very approachable and ready with there answers. If a member of the club they also gave 5% discount which covers the postage

I've often wondered if folk in the Czech Republic meter their carb jets differently to us?

I understood that they were different bikes and models, cc's etc, eventually, but surely a 125 can't be expected to run on 175 jetting and vice versa?

I will try my CZ carb out one day on my D7 soon though.
