To start or not!

The time came last week to have a go at starting the Triumph. 

Oils liberally put over the top end, gearbox, chain case and engine oil filled and a remote petrol tank setup. By the way, if you intend to use a remote tank, put a filter / tap on it - it is a pain with no way of switching off the fuel! Earth cable setup to have the ability to stop the engine (on the magneto) - ever hopefull!

Just a few checks and I could try the kick start!

Well, firstly there was fuel dribbling out of the carb. Secondly, I could not get a spark - it seemed OK on the bench and lastly, the clutch slipped. So it was back in the workshop and a bit of dismantling.

The short answer was:

  • The carb float was not sitting properly on its shaft - easily remedied.
  • The clutch springs were a little weak (too short) so some new ones were ordered (they are meant to be 1.5" long and these were a little short). In addition, I was probably using a slightly thick hydraulic oil for the primary case and so will try SAE20 next time)
  • The magneto was removed and unless you got a drill onto the unit, there was no spark. I decided to send off the magneto to be tested and repaired as necessary. As my K2F magneto has a smaller bearing in it (19mm aperture by the seal as opposed to 25mm by the seal) it was decided to replace the whole thing with a fully reconditioned unit.
Until I get the magneto and clutch springs, I will carry on and sort the new wiring out on the bike. Await round 2!!
