    I'm trying to rebuild the Holley 1940 carburetor that I have for my '68 mustang. My car has a 250 engine from a '71 mustang. I think I have most of the parts I need to rebuild the carburetor, however, I'm missing the fast idle cam and I can't seem to find any online or any store. Does anyone...

    Hey guys have a question about a Holley carb I was rebuilding for my '68. This is the first Holley I've ever messed with. I bought it used and it was all intact and in really really good shape and had a brand new electric choke put on it. (Only paid $20 for it too!) I got it home and started...

    Recently, I bought a Quick Fuel 680 HR vacuum secondary carburetor, and being a Quick Fuel, it is almost fully tunable. Yeah, 680 might be a bit big, but I like to rev high, and some extra tuning can get things to work well down low. I have used both an Edelbrock 1406 and a Holley 570 Street...

    My mechanic just called me and said he doesn't think my 1969 Holley carburetor is rebuild-able. He suggested I get a new one. I do not know if the Holly was original to the car, but I'm assuming it is, as it has not otherwise been modified. The parts store says $350. Is that reasonable? What is...

    I have a 65 mustang with a 351 windsor under the hood, after sitting for 10 months because of a drivetrain issue that I am now finally getting fixed, I found that she is leaking heavy amounts of fuel out of the carb. Starts right up, runs alright as far as I know because as of this moment the...

    Hey guys, I got a rebuilt 302 with a 1850 - 3 holley carburetor that came with the car when i bought it. (before the engine was rebuilt). I'm having trouble tuning this carburetor. I have read a few threads and they say that these carburetors are only for specific types of engines, does this...

    Ok, short and sweet, here's what I'm after: '87 5.0 block in my '65 mustang, full roller, edelbrock aluminum heads, performer intake (matched to heads), blower cam, all those kinds of goodies. Novi 2000 blower setup with carb box for some '60's style original look. Issue is my carb. I got...

    I am currently using float #16r-587a on my Holley R4996. I got the carburetor without that float spring and I was looking online for some help and noticed that some floats like the copper ones have springs. My carburetor is overflowing with the adjustment screw bottomed out and was wondering...

    I have been given a Holley 199R-7948-5 4 barrel carburetor but the 289 intake manifold is for the 2 barrel. If I want to use the Holley, must I change intake manifold or is there some kind of adapter that will allow me to use this carburetor. If I must change the manifold, what is recommended...

    OK, I have searched the internet and narrowed it down to the retrotek Powerjectionor the Holley Avenger or HP Efi system. I would like to know if anyonw has use any of these and can offer some comments or suggestions. However, there is a twist. We are currently rebuilding the original 289 with...

    I've recently been working on a new-to-me 67 coupe with a 289 which has a Holley 65-4412 carburetor. It is absolutely drinking gasoline and doesn't seem to have much power and i have been thinking that the carb may be set improperly. As i don't have any real experience with tuning carburetors...

    Hello everyone, I have had problems with my fuel system lately. It seems to be drawing air but not leaking. This is causing me to stall after a long idle. I even tested by sucking on the hose and can see air bubbles in the glass filter. I currently am running some performance mech. fuel pump. I...

    ya i have rebuilt the carb on my 66 200ci I6, but i definitely need a new one. i know that pony remade the autolite 1100. but i was wondering if holley made one to fit this engine... i cant find it anywhere, or where other types of better carburetors can be found. thanks i appreciate it =)

    Good Morning, back to work! I recently bought a 66 coupe with a Holley Street Avenger that was idling very high. I'm new to all this, by no means a mechanic, and know next to nothing about carbs. I finally realized the choke was not connected to a good 12V source and the car was always on...
