Im trying to source a setter jet for a mikuni VM 32 Sh carburetor here in the UK,,The carb is marked 308 E2,, im assuming its the original for my 73 rt 360,i will also need the washer,if i cannot get one from these shores i may have to try the USA,but id rather not pay more for shipping than the item. Can any of you out there point me in the right direction, cheers in advance.

There are options to eliminate the jet setter,

Here is a jet setter i found googling away. Price is high--but. Did you break the thread off yours as i've come close to doing that but had a spare. Couldn't find the washer [checked his other listings too]. Any washer would do but original brass washer is quite thick & probably helps the Oring get fully compressed down past the taper start of the bowl cavity. If i was stuck i'd screw a main jet direct into the needle 'jet with a washer'. Thread is slightly different but can be done.

Motocarb should have what you want.

Great responces ,ive emailed Motocarb hopefully they can help,i dont want to go down the alternative route,and the one in the US on ebay may be my last expensive resort,and yes the carb body came without the Setter in place,it was separate with the threads missing. 

Sorted it,Motocarb had one in stock,brilliant I searched everywhere ,cheers once again

Hopefully they're not sending you the one that they put to one side for me! 

Niche Cycle has jet setters at a reasonable price.  Not sure if they have the exact one you need

Keep in mind there are two different types / styles of the jet setter. There's one that has same thread as main jet for the 159 type needle jet and there's one with different thread for the 188 type needle jet. Just a thought.
 

So would the setter jet from a 1974 DT250/DT360  # 276-14145-00 be the same as a 1973 RT360 # 214-14145-00
Would it work?
