The number after the dcoe does refer to the factory chokes,they all have the same body in each size eg 40DCOE28 has the same body as a 40DCOE31. Just Jet it correctly and you will be much happier, I made this mistake once and won't do it again.

What are your exact choke jets etc? Your 1650 1300 pistons? What cam are you running? 234?

30W engine oil is made for early diesel Engine.Usualy Detroits but also English and Jap ie Isusu 3.0l Bighorn engines.
You will pick this up for round $35 to $40.Ausy oils got more ZDDP additive in them cause no Govt ban like Euro and
USA made ones.

If you are CHCh try undercars services for Gulf Western or Trans Diesel for Agip

I'm running a pretty standard motor, it's a LC 1600 with a BCF2 cam and thats it. I run much bigger than what you have so I would expect that yours should be bigger again. I'll have a dig and see if I have it written down somewhere, but otherwise I'll pull them out tonight.

Thatl be great thanks. I well re jet it correctly. Will it do any damage if I run it in as it is? (it ran fine before storage apparently) What I want to do is get it all working and run in, then dyno it with someone who knows what theyr doing and they can tell me what jets I need. No point in me buying jets now and then having to re jet after a dyno.

Other thought is I buy the right jets and not dyno it at all because itl probably be pretty good. :?

I wouldn't but that is just me, It depends on who is doing the work, you are in AKL right? I know when I got Palmside to jet my carbs, he kept my old ones and gave me a discount on the new ones. I would imagine if you got Weberspecs to do it, tell him the spec of your motor he would jet it to get it running, and then when you took it to get tuned he would just swap the jets that he originally supplied to get it spot on, could be worth a call?

Ok, found this from an old thread I made.
http://www.classicrallyclub.com.au/docs ... ndrews.pdf

It's pretty good I think, and seems to cover what I think is neccessary.

Ok, this is what I have (Dell'Orto)

Chokes: 33
Auxiliary Venturi 7848.1

Main Jet: 132
Emulsion tube: 7772.6
Air corrector: 170

Idle Jet: 58
Idle emulsion tube: 7850.4
Pump Jet: 55

and it runs well, but could possibly do with a bit more fuel up top with the new cam.

Cheers rookie, appreciated.

Spoke to Murry at weberspecialties. He reckoned 32 choke, 125-130 main, 170 air, 45 pump, 175 needle, same idle, same venturi.

He said the carbs were off a 1300 alfa.

350bux off the top of his head to change all that. So ill go see him saturday and hopefully get it sorted for not much more than 350.

See if I can get it running over the long weekend! :D
