OK, update:
Manifold is at the machinist to drill a few holes. Pray he does it right. 0.1mm tolerance fit, to allow for gluing the injector bungs in place with Loctite 638. (suitable to 200degC, with 70% of strength left at 150degC, should work).
Also found a guy that makes shaft sealing kits for the inside of the IDA webers. This is a known air leak point, and can generate erratic idles, difficult to balance webers etc. Thought it was worth a shot for 15dollar, and supporting someone in the community.
Also fabbed all the fuel lines, that connect the fuel 'banjo' to the AN fitting T-pieces, by using the float/fuel bowl space.
Good fit, happy with this.
Want to make a reliable throttle pedal position sensor, as TPS's are used for a crucial part of the tuning of ITB's in modern day ECU's.
So, sensor is key, but more importantly is a good reliable connection between the throttle shaft and the sensor.
Commercially available kits are not working for me, as they apear sloppy and prone to significant hysteresis.
Was drawing up an aluminium adapter, transferring the M7x1.0 thread on the throttle shaft, to a 8mm round bar for the 'D-type' 8mm orifice in the typical TPS sensors.. Not a massive big deal, but found that there are more nut-jobs like myself in the world.
Emerald ECU manufacturer actually makes these adapters, and sells them for 2.5 pounds each. HOW?
Love those kind of finds.. Ordered a bunch of those, so I can mess up my filing and still get a tight fit in the TPS!
