You don't need those needles. Just use the Hitachi needles.

Here is some of the info I came across:

the linkage is easy ish, mine had a home made one of threaded rod cut to length, them 2 edges ground flat to fit into the carbs, then nuts holding and spacing some striker plates to the shaft. then a cable linkage to turn it all.

Just sold it to antoehr member, he might take a pic to give you an idea.

I didnt make the strikers, but had to remake the rod once.

The L18T needle is almost the same as the A12GX needle. So no worries. But the dome spring is different that's an easy swap.

Hitachis don't have 500 needles. There are only about 20 for the 38mm carbs.

Met ons k@k rand exchange rate seker weer duur storie.

Not sure about local, but can import, don't know for how much tho

Ja, but the big question. Are they still available. When my motor is done, I will probably have to change needles to suite.

500 different needles for jetting

500 different carbs?
Please PM me your email again, I can't find it now.

there is lots more room in my mailbox, try sending them 2 or 3 at a time, I didn't receive anything

Emissions can be blocked of, wich design of carb is better?
Any apparently you need to re jet anyway, and there are like around 500 different ones!!!
