Got the reamer for the scavenge pump. These are used by hand to accurately ream out an undersized hole to the correct size, and very precise too.
Got an extremely good deal also, its a Dormer reamer, the normal price was 68euro, I got it for 25euro as I got other stuff too off the same guy.
You could get one for a tenner but they tend to be crap.
Onto mounting the throttle potentiometer(pot) and link arm...
The ecu uses this sender to gauge throttle opening in order to calculate how much fuel is required. This senders range is I think 80 degrees, or just under a quarter turn from idle to wide open throttle. This can be all calibrated with the ecu software but the linkage still has to be near right.
It works similar to a volume knob on a radio.
I have no idea what this is off as I found it in my parts bin, its the same as many generic Pot senders and its new.
You can see the shape my spindle needs to be to fit into it and turn it internally>
The sender also has slotted mounting holes to enable it to be clocked if its a touch out of range.
Onto the link bar to fit onto throttle tab and attach to the crank arm which will turn sender>
6mm aluminium plate, spec, 6061>
Although this link bar has no real load on it it needs to be stout enough so that it does not vibrate, something I saw once where a guy had used some 2.5mm wire as a link from his butterfly throttles to a remote mount sender, at around 2200rpm the wire started to vibrate much like a bonnet stay does sometimes. This vibration could be seen when looking at the pot input values while the engine was running, I made a better linkage setup for him and he had no probs after that. I don't want that happening with my setup.
Drilled out and reamed to 9.80mm>
Pressing in the bushes>
End radius cut and linnished>
Bending, first bend>
Second bend, checked and adjusted>
Lightening hole centres marked and centre punched>
Drilled, ready for clean-up>
Ends reduced down to bush width>
Link is very light and extremely strong.
Ill be mounting the pot sender next and making the second crank style link to attach to the link above.
