Re: Weber Jets Question

[Mick Ralph]

Richard I have to agree with Kris The dyno place should have all the jets u will need and if he's any good he should be able to have a good "stab in the dark' first too Weber jets are hellish expensive and it seems that so many different combinations will work. I have two sets of jets for my 45's. One for coast altitude and one set for over 1000m altitude. Its hard to feel the difference running around (my) town on either set but u can really feel the difference on a racetrack and the fuel economy! The thing is when you look at the numbers on the jets they don't seem to run sequentially or have relevance.. ie  on one set I use #195 main jets and on the other set I used #145 main jets    BUT they work fine. Does the engine run at all? Did the carbs come off a similar engine? Anyway   my calculator says that if u redline at 6000rpm Choke 36 Main jet 145 Emulsion tubes F9/F16/F2 (lean to rich) Air correctors 180 Idle jets 50F9 Pump jets 40 Aux venturis 4.5 Hope this helps Cheers Mick ----- Original Message ----- From: Kristian Walsham To: [EMAIL PROTECTED] Sent: Saturday, August 30, 2003 7:09 AM Subject: Re: Weber Jets Question Hi Richard,                  It would be alot cheaper to tow your car to the dyno than try to guess the jetting. Once there they will most likely change the jetting anyway so you will have just waisted your money. Trailer hire is about $50 or so, jets are probably $30 each new???? x4 of.   Where are you getting it dynoed?   Kris. ----- Original Message ----- From: Richard Webb To: [EMAIL PROTECTED] Sent: Saturday, August 30, 2003 1:15 PM Subject: Weber Jets Question Hi all I was wondering if anyone had any idea which weber jets would match a L20b: Stock bottom end, ported head (u67) with a Crow Cam (30832) running twin 40mm webers   http://www.crowcams.com.au/templates/Catalogue-Datsun-OHC.shtml   I just need to know fairly close so I can jet it before I drive it to the Dyno... surely someone has the same setup as me...   Also where to buy and how much to expect to pay :).... All this money I should have done a bloody SR20DET conversion.....   Cheers,   Richard     --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/[EMAIL PROTECTED]/ --------------------------------------------------------------------- --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/[EMAIL PROTECTED]/ --------------------------------------------------------------------- --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/[EMAIL PROTECTED]/ ---------------------------------------------------------------------
