after 10 million fone calls looks like mic at ovaboost will tune the motor but doesnt have jets but can fill and redrill so hoping i dont have to go bigger

I have never been a fan of fill and redrill of weber jets. I have read articles which dont give favourable optimum performance when done. From memory genuine weber jets are "size stamped" only after being tested for there flow characterisics instead of the diameter of the hole drilled in them.

Unfortuantely it looks like you dont have much of an option though. For tuning purposes I would fill and drill the jet and after tuning, I would replace the jet with a new one in that desired size.

cheers well im in a rush atm but wonce its all done i dont mind buying jets and getting it retuned ( guess thats the next hard bit is finding n buying the jets ) are they very dear ?

jets aren't too bad, emulsion tubes etc are a bit exy..

i thought you were tuning the sr

lol the sr20 is way off

is automotive tuning centre in welshpool still open?
Darrell Penley used to always have weberised rally and race cars on the dyno all the time there.
but I also think the good old 'tune by ear' guys are getting rather thin on the ground

Darryl shut up shop years ago
He did the initial setup on my carbs
Then I have my race guy do the rest

yer all ways went to ATC/ him... closed now :(

somebody needs to Wake Darrel up and get him to teach me..
