weber 42dcoe on 13b
recently aquired a weber 42 off a buddy to use on my 13b since my dellorto 48 is pretty screwed up. my question is what jet sizes should i use to make sure its not running lean or anything.
|
carb came off a turbo 13b.. im really just asking if i should upgrade or if i can just get away with jetting
|
You can get away with it but it won't be enough for a 13B. Not enough CFM for a non boosted 13B.

i am a fan of new things and since my dellorto is quite a fucked situation i may just buy a nice new weber, what would you recommend? 45 or 48?
worse than the Dellorto. What kind of issues is the Dell giving you? Did you check this site for jetting for the Dell on a 13B Gruntled.com - Dellorto - Jetting ? |

Consensus on the weber for a rotary would be a 48 DCD. Getting the 48 DCOE would be

plus im not trying to have to buy a new intake + carb. cant quite afford both at the same time since i have multiple projects lol.

Carbies take patience and time to get tuned right, its not like EFI in a modern car. You should try a nikki.

How is the Dellorto screwed up?
Unless it's been drilled or otherwise hacked up, it probably needs the correct jetting or new soft parts. Floats can be adjusted. I think tuning it will be cheaper than getting a whole other carb. There's a tuning book at the bottom of the RX-7 Manuals page on foxed.ca if you are not familiar with them.

I thought they're very similar with the biggest difference is the DHLA has a diaphragm accelerator pump, Weber has a metal plunger. And Dellorto jets have a finer range. Where have you seen a 48 DCD? The Rotary Engineering kit is dual 36 DCD. Did you mean IDA? |

Sounds like it's hacked up for sure. Carry on.
