I had originally opened and closed the throttle assembly with an Aldi tool but was only able to fit one of the spacers.
I then failed to re-open the assembly with the same tool - so I ordered the tri-top head from Amazon which only arrived today.
I had to file down the thick-side of the spacer for the right hand side and after three attempts this is what happened. ( see attached image).
Would you please re-send me - in your own time - the right (forward) spacer - that's the one with the thick side - but would you make the thick side the same size as the other side?
Let me know what I owe you and I will send on the payment immediately.
