Zama carburetor identification

[gkitf16]

I have a McCulloch Eager Beaver IV 28cc 2-stroke blower with a Zama carb. I can't quite figure out Zama's model # for it to order the correct carb rebuild kit. I see that it's a C1U, but there are several other numbers/codes that don't match up in their parts lists. Here's a couple of pics showing the codes stamped on the carb body.

The model number is staring you in the face.

C1U-M35A

And while you are buying parts. some new fuel lines are in order.
Pulling them out so the tank can seal agains a new place is a very temporary fix .
There is a Stihl ( I think ) single hole fuel tank grommet that I use a lot to get a better seal .
Not totally sure of the part number as I bought 1000 from a supplier in China

Thanks guys. I'm pretty good at basic diagnostics, I just was missing the model number syntax used for Zama's. Do you happen to recall the fuel and return line sizes? if I recall they were 2 slightly different sizes. They usually are pretty snug to push on when new. I have found heating a cup of water then soaking the end for a moment to soften helps a lot. When it cools, it's not coming loose!

Both lines in your image appears to be the same size 3/16 od lines.

Don't know the actual size, and don't bother to try & memorise it because some makers use different size OD's
And yes the intake is a smaller diameter and thicker walled tube to prevent it collapsing
The return line is thicker id and thinner wall

I thought one was smaller. Ordered a 4 size pk. of Tygon 2 ft on ebay, genuine Zama primer bulb, Zama RB-29 kit and fuel filter. Thank you for your help.

Commonly when two different size it is obvious when view in images. The two most common sizes is 3/32" x 3/16" (2.4mm x 4.8mm) and .080" x .140" (2mm x 3.5mm). There is also one above this that old Homelites use which is .117" x .211".

But when replacing lines here I just pull out the two bulk lines and take them to the work bench.
