16v kr pinking

[leeroy20vt]

rite been to garage this morning the co2s ect were a liitle low so turned them up a tad
compression is 200 psi on 2 bores and around 185 psi on other 2 wierd

also checked ignition timing and is spot on 

any more ideas

within 15 psi is ok, if its a young engine it'll still be setteling, if its old thats weepage past valve seats and rings

cheers danny the engine has done 148k i think if it original but it has had head rebuilt ported and polished to fast road use so it says on reciept lol   also rehoned and piston rings i think its done around 600 miles since this has all been done

it's no where near setteled then,   compression results are near as dammit optimal

Hi
Is it just a rado engine or is it a rado shell ?

so after setting up the co and using super unleaded its pinking exactly the same?

sounds like a fuel delivery problem then

though saying that i have found kjet takes a few days to settle after a tweak 

oh dear that post just earned me a geek medal

lol u geek haha 

yes m8 seems the same i have even retarded timing a  little more altho its lackin even more power its still pinking will run it for a few more days like u say may settle down but i dout it

my next option is find some were that can check fuel pressure under load i think ?

Hi
Thanks for confirmimg that it is a rado shell.
There is a fuel pump inside the fuel tank and one outside. If the rado is a 1990 one, then it may be time to change one of the pumps at a time.

yes i was thinking this but fuel pressure on tick over is good but dont know under load ?

does any one know if the intank pump is the same as a mk2 8v or would it have to be a 16v

also sorry m8 i didnt see ur request for a picy so here it is

still got the mk2s tho lol
