What else do I need?
The Buzzwangle tool screws into the flywheel extractor threads on your ignition system, providing a solid, stable platform for our Buzzwangle-O-Meter 360. This magnetic meter is superior to many commercial inclinometers which only measure in 90-degree quadrants.
In order to set ignition timing you will also require a piston stop tool. We have produced a special adjustable Buzzwangle Piston Stop which can be set for almost any engine. The adjustable centre bolt means it will work on cylinder heads with concentric or offset spark plug positions. The Piston stop tool is reversible to fit either 14mm or 10mm spark plug threads.
Both of these items are supplied in the full Buzzwangle timing kit. Additionally you will need a timing strobe gun (the simpler the better) and possibly a pocket calculator.
Q: What limitations are there on use of the Buzzwangle?
A: The Buzzwangle reads angle position by referencing earth gravity. It is highly accurate but only when the crankshaft is in a horizontal axis. If the crankshaft is not horizontal (e.g. so the meter is tipped forwards or backwards) then the Buzzwangle-O-Meter will display ‘ERR’ signalling an alignment error. If you see this message re-angle the engine so the crankshaft is in a horizontal axis before measuring again.
Q: My Buzzwangle-O-Meter displays 'ERR' on the screen. What can I do?
A: Place the meter on a flat surface and check again. It displays ERR as an error if it is tilted so the device front face is not in a vertical plane.
Q: The central locking screw does not fasten against my crankshaft. What can I do?
A: The purpose of the tool is to provide a solid platform for the meter. If the tool can be screwed firmly into the flywheel by hand so it can't be accidentally knocked then you do not really need to worry about the locking-screw. The supplied locking screw is 25mm long and will meet the ends of most crankshafts but if it is too short then you can use a 30mm long dome head Allen screw. Alternatively you can add something like a large bearing ball BEFORE fitting the tool to effectively extend the reach of the screw. Do not over-tighten the locking screw!
Q: Can the Buzzwangle Tool be used as a flywheel puller or extractor?
A: No, the threads used are not designed for that job and you risk breaking the tool.
Q: Why does the Buzzwangle Tool in the videos look different to the production model?
A: The videos were made with the prototype version made by an investment casting process, however this proved to be a problematic method of construction for a tool this shape due to warping as the steel cooled. After months of failed attempts we gave up and decided to have the whole thing CNC-machined from billet steel and then chrome-plated. It is a more expensive process but the quality is vastly more consistent.
Q: Whose idea was the Buzzwangle tool?
A: Sticky - the author of the best-selling 'Complete Spanner's Manual for Lambretta Scooters' - came up with the idea of an inclinometer mount that attached to the the flywheel extractor threads in 2016 and applied for a patent on this idea and several variations of it in 2017. Buzzwangle is produced in collaboration with The Scooter Republic. It took until August 2018 for us to overcome technical problems and to release a product that we are proud of.
