Brown goo and tanks!

I have got a problem with brown goo coating the inside of the carburetters
on my TZR250 thats has been standing for many years. I guess its from the
old petrol. Anyone got any hot tips on how to clean them up?
Also the is tank well rusty inside but almost perfect on the outside whats
the best way to deal with this problem.
I know these are basic questions but we all start somewhere.

There is/was a product called carb cleaner in a spray can which takes off
all that 'goo' I have a can but don't know where it came from I assume it is
still available.
The tank is a bit easier - a product called Petseal, from Autocycle
Engineering (01384 253030) is what you need. I have used it myself and
found that it works .

Nice one. That said it won't help when the tank coating is flaking
off...

Make sure you get the proper 'professional' (aka very nasty
ingredients) carb cleaner as the consumer type stuff has slightly more
cleaning ability than lukewarm water...

 

Timo Geusch fascinated us all by saying...

I've only ever heard of this happening on BMWs, but then again, I've only
ever heard of BMW coating tanks. Sounds like a dumb idea to me.

 

A complete strip and lots of time with carb cleaner, toothbrush, and HP
air. Sorry.

 

If the gum is well 'set' try brake fluid (ordinary non-silicone type). You
will have to change any rubber o-rings though.
cheers,

It is (a dumb idea), probably, as the coating inside my tank is indeed
flaking off, and coating the filters, and being a b****y nuisance.

I'm going to try Petseal, I think, as I've heard good reports of it.
Comments anyone?

Carb. cleaner works, but it contains toluene, which is nasty stuff -
worse if you nitrate it! It's only available in aerosol form at my local
car accessory place - really stooopid, as it's dangerous by skin
absorption and by inhalation.

So I got some, and yes, it works. It also causes headaches (see above),
and melts o-rings and possibly the diaphragms too (didn't test this!).

So I tried some alternatives. To my surprise, Swarfega works really
well, worked into the crevices with a small test tube brush and washed
off with water. Lifted both the grease and the 'varnish' nicely.

I did use carb cleaner for the really small passages (it comes with a
WD40-type thin pipe).

HTH.

Cheers every one...they are slowly coming clean....and I can get a bit of
toluene from work.
Don't worry I'll protect myself..against toluene that is

I use the tumble dryer for this, with the heat off of course.
Urmm you do have to wrap the tank in blankets to stop it flying around
inside the drum.
Just in case anyone is going to try this
And I have found it best for your marital bliss if swmbo is out at the
time ;(((

 

Or old baby milk tin, a few litres of cellouse paint thinners (about £7
per 5L tin). Break carb into big chunks (float bowl off, CV diaphragm
out) and leave to soak overnight.

Blow through with air (bike pump if you don't have a compressor), job
done.

 

Thanks,
Just one thing....CV diaphragm.......not in TZR land
Vin

 

It was a generic answer, never having had a TZR I didn't know.

The point still stands that rubbery bits don't fare too well in a bath of
paint thinners. There again neither does the varnish and goo you want
shot of...

 

Yeah I knew that really I wasn't having a go....everyone has been very
helpful
I am sure I will have plenty more dumb questions over the next few weeks...
Vin

 

No. Meaning "constant vacuum" or "constant velocity". Some CV carbs have
metal pistons, not rubber diaphragms.

But it isn't a two-stroke, is it?

No worries, we all have loads of them, and sometimes we even know the
answer. That said, some of the answers might be found in the FAQ (link
in my .sig) which also happens to describe the posting style we like
to see here.

 

It does? Blimey.
