Topic: not another carb question.

[yotadork83]

 i have a good running carb out of a 86 that i am putting in a 79. now i have searched and have not found what i was looking for. i want to simplify the carb as much as possible. and still jhave it run ok there is no emissions in th truck now and am not planning on putting them back in. i know that i can block all the vacume ports and eliminate the choke. and it will run in warm weather but it gets cold here so i need a choke. i dont want to buy another weber if i can avoid it, but they are simple and i know they work i have never had any luck in the cold with the stock system. is the a thread that has all of this info because i havent found it yet. i just need it to be simplifed as much as possible and work.

is your 79 running a 22r?

[RN37DD]

yes you can eliminate a lot of the features on the stock 22r carb. just for fun look at the stock racing carbs by LCE. but most of the features on the stock 22r carb work really well the way they are. in fact i wish i could mod the idle up feature and AAP to work on my weber. Better MPG. if you still want to .. just take out one feature at a time and see how you like it.

79s used a 20r didnt they?

[RN37DD]

yeah 79's used the 20r. but some people put 22r carbs on them for more hp.  yeah i'm just guessing on what he has. my 79 20/22r. on an old truck who knows.

[yotadork83 [OP]]

yeah sorry it does have a 22r. and i cant just eliminate one system at a time there is nothing there.

do you know what year 22r carburetor. are the vacuum lines hooked up to your distributor?

[yotadork83 [OP]]

read the first post it is out of a 86 and i havent done this yet and i am asking so i can figure out what to hook up. and where for the most part all 22r carbs are the same casting so it dosent matter.

I would say you want to provide vacuum to the existing ports.  You will lose much of the functionality of the carb without them.  If the carb can't properly measure airflow and meter fuel then you are essentially just dumping gas in your engine arbitrarily.
