Redline 44 idf not ida mixture screws differ

[blacka1vw]

I’m putting a kit in this 44 idf for a friend. I thought it was strange that it has different mixture screws on each barrel. One blunt mixture screw without a seat and one tapered with a brass seat. Is this normal? I’m not experienced with this carb.

Think both barrels are supposed to have brass needle seats and pointed idle mix screw...

almost looks like the "blunt" one is the seat pushed through the housing,,,

did you unscrew them both?

[blacka1vw]

I unscrewed them both removed the deal and washer and spring looked them over. In this picture they are just hand threaded in to their stops. The one pictured on the left is the blunt no brass. The one on the right is the brass seat you can see. Owner assured me he bought it new from redline with these mixture screws.

The blunt one is also a hex head with slot. The one that is tapered is the knurled type Head with the slot just like the ones that come in the kit. Tomorrow I’ll snap picture of the screws.

Here are the mixture screws

Looks to me like you have a IDF, not IDA, and it has a mixture screw with the needle broken off and your missing your brass seat.

You need more parts to make that carb work correctly. If you rebuild it without those parts, it will be a waste of a kit.






For example of how it should look, one of my IDF cores:

You are correct it is an idf that was my bad.

I do believe the owner that he bought this carb “new”as part of a kit. And the blunt tip hex screw doesn’t appear to be broken it’s actually threaded longer than the other tapered one. I’m gonna see if we can’t get any information from the dealer.

from here it looks like you might need a new mixture screw seat, luckily these are avaliable:

As well as another mixture screw, washer and o-ring. Good luck.

The top picture of the screws, is the repair kit, the middle screws are the early and late fuel mixture screws, along with an original style brass insert to the body, and the bottom screw is an idle stop off a dellorto, and from the other carburetors I just finished for a customer you can see the idle stop screw heads, the early style is hexed head and the later style is around knurled head for the idle stops on the IDF carbs, so the one screw you have appears to be a idle stop screw that somebody put in to the fuel mixture circuit
