Weber idf40 vs Weber idf44

What were the "every solution"?

Did you clean the idle circuit first?

If that didn't work, did you follow the instructions on that 2nd link that I gave you on your other thread?

If you get new carbs, you'll have to do all of what's on the 2nd link to set them up. You might as well try that with the carbs you have first. New carbs do not come set up out of the box.

I had to do that setup to my carbs when I got my car, as most everyone on this forum.

We're just trying to help, not putting you down.

I have just about tried every solution

Did you remove the 1/2 manifold and check the gasket? Have you taken the carb off the manifold and removed the top?

There's a lot to do between "just about" and "I have tried everything".

FWIW, 40 or 44, you're going to have to learn how to do this stuff. I had a set of 40s on my first speedster (20 years ago) that kicked my butt, and several that nearly have since. There's no magic carburetor that's going to provide snappy performance without a steep learning curve. If you stick with it, you will learn. It's just not the nature of these things to give you anything for free.

I have removed the carbs and checked the gaskets. I did not remove the manifold gasket. I will try this.

Thank you,

Renfrance

I have not setup the carbs as shown in the video you provided. I was under the misconception that new carbs would be already setup and would lemonade the setup procedure in the video.

My bad,

Renfrance

You had a new cam put in the motor, correct @Renfrance?

Removing carbs from the motor REQUIRES them to be disassembled and checked over in my opinion. This is good advice, ask anyone here about me and Webers. We get along fine, Webers and I.

They may not need any parts, but disassembly sometimes damages gaskets and O-rings. So it's a GREAT idea to have rebuild kits in hand.

My rule on carbs: 2000cc and under, 40 IDF. Over 2000cc, 44IDF.

Start with the article "Setting Up IDFs":

The engine had a hotter cam when I bought the car but I don’t know any info past that. It looks as though I will need to tear apart the carbs. Can you tell me where the best place is to purchase the rebuild kits?

Thank you,

Renfrance

Since you're in Europe, I'll not even attempt to help you find a vendor. Get in touch with some VW clubs in your area or google it.

I'm not picking on you, but saying it "has a hotter cam" doesn't really mean anything. We need more information to help you: exactly what "hotter cam", heads(valve size, porting), compression ratio, displacement(bore and stroke), and what exhaust system.

Without this info, nobody in the world can help you.

No information available on the engine specs were available on the engine when purchased. It was a factory built cmc in 1983.
I am aware Indiana is considered by some as a foreign country but we became a state in 1816. Lol

Renfrance

HA! I assumed you were in France. My bad.

1983, huh? It's probably no bigger than a 2110, most probably an 1835 or so. Not a lot of strokers built back then, but I could be wrong. Only way to know for sure is to pull a head, measure cylinder diameter and stroke.

Redline Weber, CB Performance, and aircooled.net are good sources.

Thank you for the Redline information.

Renfrance

Please humor me.

Before you tear the carbs apart, pretty please take off the 1/2 intake manifold at the head. It's 2 bolts. Take it off and shoot some pictures of the head and the manifold with your phone, then post them here.

We've all been here at one time or another. It's by far the weak link on these engines.

Will do.
Thank you

Fixed that for you Stan.

So you did.

Actually, the greatest learning opportunity is LISTENING to experience then EXACTLY FOLLOWING the advice given.
