sprint engine advice

[andyh]

hi all<br>
I've fitted a sprint engine to my tr7 over the winter (had to try and get a bit of decent performance out of it) and have a few questions<br>
whats the timing for setting with a strobe? my manual gives 10btc static and thats what I strobed it up to at 1000 revs<br>
<br>
I,ve shimmed the tappets up to 15 thou when cold but it still sounds a bit tappety is this ok?<br>
<br>
and finally anybody know the best needles to use in the carbs with k+n filters and a tubular manifold?<br>
thanks in advance<br>

tubular manifold...-sigh-<br>
<br>
The standard sprint rich needle is the BBT, but I should think you would want richer in the higher stations thanks to your better breathing.<br>
<br>
This is a very handy spreadsheet that should be able to sort you out.<br>

when there are so many good 1300 dolomite shells around...<br>
Anyway the static timing sounds about right and the valve clearances are of anything on the tight side unless you have a non standard cam, which tend to use clearances in the 8 thou inlet and 9 exhauts sort of range.<br>
It shouldn't sound too tappety with those clearances.<br>
Theres a bit more top end noise than an 8 valve cos theres a lot more going on. Can you be sure oil is getting through the cam followers okay?<br>
I think ABT's may do but others have more idea of this.<br>
Mine has a diffrent cam and I forget what we used its so long ago...<br>
