Hi

Has anyone heard of carb cleaning spray?

I saw some, in my local parts shop. It is in an aerosol can, and you are ment to spray it into the carb when the engines on.

Anyway, Im about to rebuild and service my HS4's and was wondering if this is a suitable spray to use, or weather this is just a spray to use when the ending is running (as directed on the tin)

If not, what is the best thing to clean the carb up with? petrol??

Thanks

Yes I can use a parafin based parts washer in the workshop at work. It is great for cleaning stuff as it degreases an cleans.

Petrol is OK but not that nice to work with. WD40 can leave a residue but I am siure it would be fine for carbs though.

If you're talking about doing a major cleaning of your carb(s), the stuff in the spray can will work just fine without the engine running. Over here you can also find carb/parts cleaner in 1 gallon metal "paint" cans and inside is a dip basket so you can soak parts in the solvent.

Gasoline and WD40 are not effective at cleaning carbs. Buy the spray or dip carb cleaner. It is amazing how quickly it will work. I find applying some of the solvent and using what we call and "acid brush" to scrub it in works amazingly well. An acid brush is usually used by plumbers to apply flux to copper pipes. It's a disposable mini paint brush with a tubular sheet metal handle with boar bristles crimped in the end. Cheap, unaffected by solvents, and disposable. Use the brush to scrub the carb cleaner into the nooks and crannies, then flush the parts with a spray of carb cleaner to wash away what you've dissolved.

by the way, you can spray the carb rubber and plastic parts with carb cleaner. HOWEVER, do NOT soak rubber and plastic parts in the carb cleaner as they will be damaged. Spray, rinse, and blow the plastic and rubber parts dry.

you could always try looking in your local pound/cheapy shop.

they do carb cleaner in a blue tin, when i see it i normally clear their shelf of the stuff, its great for cleaning loads of stuff.

just dont spray it on grass or plants, it kills them in seconds

That works great on the loose stuff (particularly on the outside) but it won't touch the brownish gum and varnish that builds up from old fuel. If gas would clean that off, it wouldn't form in the first place.
