Suzuki 2 Strokes

I am rebuilding the carbs on one of my T20's and ordered a set of kits from the only place I could find them, Siruis Consilidated in Canada. I got them yesterday and the float needle works fine, but the float bowl gasket is totaly different. I contacted the vnedor and he told me they would gladly take them back and refun my money, but since I need the fuel valves, I told him I would keep them anyway.
He said that they use this Keyster kit and it works fine for all except the US models of the T20, but they have had several US models returned becasue they were different and would not fit.

Does anyone know where I can get these gaskets. I tried making them but it is really hard to cut them exact enough to fit using an exacto knife.

I have no firm lead, but you might want to try Sudco at: http://www.sudco.com/flobowgas.html

Wayne, I make all my floatbowl gaskets out of 1/32" Viton. They never wear out.


Lane

Lane, where do you get the material? I don't even know what viton is.

I tried making them out of some gasket material I had but was never able to get the cut accurate enough to fit correctly, but the material I had was very hard to work with.

Wayne

Anyone know where to get the viton gasket material? Most places on the internet that list this stuff are industrial sites with minimum orders that are cost prohibitive.

Wayne

McMaster has sheets of Viton rubber for not a lot of money:

Lane - did you mean 3/32" sheets of viton? 1/32" seems awfully thin for a float bowl gasket.

Jim

Jim, They list the 1/16" at $32 + shipping for ONE sq. ft. That seems like a lot to me! Maybe I'm just expecting too much since I don;t really even know what this stuff is'

They only list 1/16" and 1/8".

Wayne

Whoops! I was looking at the cork sheets! Viton is bloody expensive. On the other hand, the Buna-N has similar properties and it's $6.74 for a 12" x 12" sheet that's 1/8" thick.

Gents, Viton is a registered trademark belonging to Dupont. This is the same stuff that is used as tip material for needles in the float valve assemblies.
This application goes wayyyyyy back to the early 60's when automotve carb overhaul kits started coming with Viton-tipped needles in them. My mechanic dad was so happy to have such durable needles that would last more than 20,000 miles or so.
Viton is gas-proof and VERY durable as well as withstanding impacts and not prone to taking a "set" i.e. doesn't crease after sitting against a sharp edge for lengthy periods. It's also dimensionally stable under pressure i.e won't "squeeze" or "flow" like some elastomers. It also is very resistant to abrasion and/or erosion by any dirt/grit in the gas stream. Viton also resists embedding of the dirt/grit in itself.
Viton is amazing stuff and has a myriad of automotive and industrial uses.

OK....that's enough (or maybe too much??) from me on that subject.

I got mine from a local rubber and gasket supplier. I told him how much I needed (a couple of square feet) and he GAVE me some scraps. I use the 1/32" stuff because it's very soft and pliable. It's easy to cut with scissors, and use a hole punch for ......duh, the holes!

Of course, Chris' former fishpond makes nice gaskets, too!

I think someone needs a new membership name,, VitonRick, yup that sounds pretty darn good too, and it should last for years or at least 20,000 miles.

Well, maybe, Allan.....
I blame it on working with engineers all those years. They'd come to me with a requirement for an item to work under specific conditions/location and I'd have to do all the legwork to figure out suitable material(s) and if the item was an off-the-shelf part or if it had to be custom made. You can see I'd soon learn about all kinds of materials and their performance specs.
Amazing how a lot of that stuff has stuck in my mind, even after all these years.

Rick i hear you cause the stuff that sticks in is usually ok, Its the stuff you need to know at the very moment that keeps drifting away as we get older it seems.
