Re: cut-outs after reving above 4500rpm

Re: cut-outs after reving above 4500rpm
Problem solved!!!! :D i was right in my assumption "the problem must be fuel related"...but i was wrong with the Needles. It was the fuel-pump!!! how comes? the car was originally a 2000cc model....the pre-previous owner fitted an electric fuel pump (his garage fitted it!!). the pump was from a qual...

Re: cut-outs after reving above 4500rpm
as said above: the problem is present with mechanical pump and with electric pump..so it cannot be the pump. the fuel-pipes are the usual ones...nothing too narrow...those pipes could feed a 8L v8 engine

Re: cut-outs after reving above 4500rpm
to exclude also the Dizzy: i replaced my PI dizzy (converted to Petronix) with a S dizzy (converted to petronix).....problem remians identical...so another "prove" that it must be fuel related. (the S dizzy came from a mate´s car)

I'm intrigued about what speed t...

Re: cut-outs after reving above 4500rpm
BAM´s are fitted and i tested BDN (very bad running).....rest was typing mistake
as said i would need needles which are identical to BAM´s until ~4000rpm and after became richer.

i just checked again the history of the car:
the engine is definately a genuine PI engine, converted to carbs.

Re: cut-outs after reving above 4500rpm
Ginetta, why didn't you adjust the jets? I would imagine that as your last needles were not entirely suitable that you set the jets as a compromise. (All needles have a near identical dimension at idle.) Burlen sell a needle chart listing dimensions of all their needles. Also remember the spring af...
