TM24 carb and Marchald filter

[sideout]

I notice reading various forums that some are using TM24 carbs with Marchald filters. They come with various adaptor inserts to suit different carb bell mouth sizes. However, the smallest is 46mm diameter while the TM24 is 44mm diameter.

So, when this combination is used are they just tightened up to compress the assembly down onto the bell mouth, or are smaller adaptors available?

Grateful as usual for any response

Cheers,

Nigel

Had a similar problem with the 25 PHBL, re-used the elbow (casa lambretta), a short length of 50mm plastic waste pipe and the 49mm adaptor. Bonded the adaptor to the pipe and used a jubilee between the elbow and the pipe.

Hot water makes the pipe easier to get into the rubber elbow as it's a tight fit. I used a jubilee so that the pipe didn't work it's way out with the movement of the engine as my filter is between the toolbox and the tank seam and is a snug fit so won't move up and down easily.

Thanks Rob, good idea!

I have also been given another suggestion, to use rubber from an old inner tube to build up the diameter.

So, one way or another I'll be able to give it a try.
