my carb is a 2brl motorcraft

and either when its cold or warmed up i can take off but when i hit a certain spot in the pedal it will cut out and want to die unless i let off or give it more gas..

sometimes i have to feather the gas to leave stop lights and what not because it want to cut out and die.. is it my float adjustment? jets? should i rebuild the carb?

 

Has it ever been rebuilt?

If it was me I would rebuild it, Rebuild kits are cheap and relatively easy to do.

 

dont know if its ever been rebuilt or not...


ive rebuilt my dads 2brl holley on his 390 79 f250

doesnt take too long.. guess thats what iam gunna have to do then..

looks like my truck will be down for awhile now.. being 16 without a job sucks!!

 

Sounds like the accelerator pump.

 

I just did my Motorcraft 2100 Friday it took about 30 minutes. I just sprayed it down with a ton of carb cleaner, rebuilt it and put it back on. Runs like champ.

 

I rebuild mine a few months back. Take lots of pictures prior to teardown, especially of the choke linkage. http://www.therangerstation.com/tech..._2150_carb.pdf

 

I had similar problems with mine and a rebuild fixed it. My problem was that the filter was allowing junk to pass through into the bowl.

 

mines a motorcraft 2100 too huh!!

i also have a 2150 sitting in my garage that needs a rebuild!

 

thanks for that link on directions on how to rebuild it.. last time i did my dads holley 2brl it was kinda confusing at times what went where and how.. hhaaha

okay i dont have any carb cleaner but will biodegradable solvent in a parts washer work fine? iam sure it would! its heated too!

 

1 more question! if u look at that pic of my motor.. right where my fuel line connects to carb is that another filter screwed into the carb?? because i removed that and put in a regular fitting..

 

Yes, that is a fuel filter.. but I see you put an inline filter on so you're good

 

ok cool.. ive had to replace my fuel filter once bcuz it clogged up!

but iam always seeing people with both filters..

makes me wonder if the one screwed to the carb is lil dirty and their truck dont run quite right.. hmm

 

Paid $15.99 and bought a rebuild kit.. for carb 2100d supposibly..

i was looking online at these carbs and i guess theres a 60's and 70's ones..

and the one i have i guess is 60's so when i was gettin the kit he first showed me the correct on for the year(76) and i said it didnt look right and to look into 60's and we found the correct kit..

ive got the carb rebuilt and put on.. i ran it and tuned it a lil.. but the question i have is that there was no replacement piece for the choke diaphragm assembly

heres a pic of what iam talkin about.. top left




and i still have a dead spot in accceleration..
iam thinkin possibly plug wires bcuz i went to check if they were all on the plugs while truck running and i got zapped by one.. agghhh haha

 

You have to buy the choke pull off separately.

 

Cody If you dont mind, can you post a pic of the linkage were your throttle hooks up to the carb? Also is it automatic? My 2100 is for a manual and I have an automatic I just want to see how thats hooked up.
