Weber Owners!!! Check in here....

Who has a Weber 32/36 that starts easy and runs perfect?

Mine runs great after warm-up. But when the engine is cold it runs rough below 1500rpm. Since I don't drive my CJ everyday, when I start the engine it takes forever to get the engine cranked. I am worried that my starter is going to burn out. I have to continuously crank-it for at least 15 seconds and the usually for another 15. I am using a fuel pressure regulator set at 2.5 and I have a fairly new mechanical fuel pump. Is anyone running a Weber off an electric fuel pump? Would this help the startup? Overall I am happy with the performance of the Weber, I would just like to get it a little better.

Thanks,

Re: Weber Owners!!! Check in here....

I had a Weber on my '87 YJ 258 for about a month. I bought it used and for some reason it took a really long time to get it started too. When I had the Carter on, the engine would just start right up. I also had the FPR. Turned out that it needed a rebuild and could not be tuned properly before it got one. I don't know if that's what casued the hard starts but the carb guy said that's what caused my bogging. Hope this helps.

Re: Weber Owners!!! Check in here....

On every carb'd vehicle I've ever owned, if it sat more than a couple of days, it would take a couple of cranks to start up. Just a little bit of gas would vaporize and evaporate out of the fuel bowls and causing the floats to drop. After the cranking, the fuel bowls would fill and it would fire right up.

I just finished off my Weber install this weekend. It took about 5 cranks (about 5 seconds long each) before the engine fired. Once it was running, it ran pretty darn well considering the gas was over a year old in the tank and the engine hadn't fired in over 2 months. A buddy of mine had a Weber and his acted the same as mine. Something else may be amiss with your setup. Double check you timing and the rest of your ignition setup. Perhaps it isn't a fuel related problem. Just my $.02

Re: Weber Owners!!! Check in here....

I put a weber on my 258 and it ran great. If it sat a while it wouldnt start right up. It also idle great even with a worn out motor.

Re: Weber Owners!!! Check in here....

I have the 36/32 on my 258. I get the same response as the rest.. If it has set more than 6 hours or so, it takes a few seconds of cranking to start. Once it does it will run like a champ.
In any position. (I dunno about upside-down yet) hehe

Re: Weber Owners!!! Check in here....

Hey rice, that's actually a new QuadraJet you have there. It's manufactured by Weber for Edelbrock. QuadraJets were originally produced by Rochester and used in most GM four barrel applications. A little harder to tune than a Holley or a Carter/Edelbrock AFB, but once they're set right, a Q-Jet is awesome. The small primaries are great for fuel mileage, part throttle operation and cruising. The massive secondaries are just a real kick in the pants when they open up.

Re: Weber Owners!!! Check in here....

Is anyone using an electric fule pump with a Weber?? I would think that it would eliminate the hard starts.

I run the 38mm, and other than running a little rich (have it leaned ALL the way out) it starts and runs just fine. No complaints from me.

Re: Weber Owners!!! Check in here....

Mine runs perfect. It starts hard when sitting for a while. I've had mine since the pre TFI upgrade and Motorcraft swap days. I am running the 32/26 and an HEI setup. I have to pump the gas a few times, and then the starter a couple of times and then everything runs great. I changed the main idle jet and got rid of the 'bog' that was occuring when stepping hard on the throttle. I run a FPR at 2 to 2.5 on road. Sometimes lower than 2.5 when Off Road.
