Hello names Denton. I have a 83 rx7 gsl. The 12a is stock, only thing it has is a webber 48ida carb. I took the carb off to clean and check venturies, choke size, jets ..etc . The car idle s and runs Okey. But you have to slowly hit the gas for it to run good. If you slam the throttle it bogs bad. Can y'all tell me what the issue is and what I need to get? It has. 45mm choke. Isn't that hugs for a stoke 12a? Has 37 mm ventries.

Needle 200
Main jets- air 120
Main-135

Small jets. /idle
Top jets -120
Bottom- 70 f10

Sorry idk to much about carbs. But if any one can help that'll be awesome! I also have the stock headers for exhaust. Thanks! -denton

 

What size are the chokes should be 40mm ,Your aid correctors are ok at 120. Main jets should be around 190. emulsion tubes F 2 . needle and seat a 3mm

 

The choke s said 45 on them there pretty thin. So my main jets should be 190? And the tube f2 not f10? The needle and seat said 200 does that mean 3mm?

 

The (auxiliary venturie says "45") on it. The venturie that slides under it says "37" on it. I didn't the main venturie was a choke also

 

200 is 2mm you need 3mm the choke marked 37mm needs to be 40mm

 

What about the auxiliary choke ? It says 45.. it's the slide on top of the main choke. With the stem thing in the middle.. lol idk what it's called. Should they be 40mm too?

 

No that one is fine and will work ok

 

What about my emulsion tubes ,? There f10 someone said I need f7?

 

Emulsion tubes F2 works the best

 

okay! thank you for all the help man

 

No problem . Glad to help
