Firstly, thanks heaps for sending the '96 rear air breathe tube, it is a different shape to the earlier models. We couldn't wait to pull our modified one off & fit the '96 tube, it fits perfectly & clears everything.
While testing been having some wot detonation issues which totally stumped us for days. We double checked everything, air leaks, timing curves, etc, & finally found it was the fuel pump side of the carbs leaking. The leak meant that the pressure was down at open throttle & not being able to supply enough fuel for what the engine needed.
The o-rings & gaskets looked all good, but obviously were'nt. Put new ones in & fixed the problem.
So now back to fun testing, running it on flat water on Saturday & in the surf on Sunday.
Have a few commitments to a magazine that have to be completed by Tuesday, so after that we'll be back into assembling the 2nd blaster so we will know how long it takes to make a complete hull.
