Carb Question
 

Not an SV but a carbs a carb?

Left the petrol turned on while stopped for a few minutes (filling up :rolleyes:) and returned to a petrol stream for the bottom of 1&2....(float bowl & air adjust screw)

My not particulary mechanical thoughts are....

1) They're overfilling with petrol so maybe the float things are sticking (? did I say non mechanical?)

2) I also need a new set of pricey seals from Mr Honda

Any advance?

(Apart from stay off the cigs)

Re: Carb Question
 

My experience of that i need a new float bowl on my ped, what seals?

Re: Carb Question
 

Float bowl gasket, small rubber o ring that hangs out on the something or other valve...

What bike and year?

Re: Carb Question
 

Try tapping the float bowls with a spanner.If that cures it you may have just got some crap stuck in the valve.

Worth a shot now it's dried out...... it had been stood a couple of weeks....

Traffics a bit of a worry though... :smt113

Still not conviced petrol leaking through the float bowl gasket's great - spose it might just (just) have been the air adjust thing. hard to tell.

Will have to make it leak again in better light rather than lying on the floor of texaco.

Any sort of instant gasket stuff any good?

From what you say I doubt it's the O-ring at the floatbowl joint, they don't dribble out in my experience, you just get a weep or staining. Far more likely to be a stuck float and flooding. If it hasn't been a regular problem it's likely to be dirt in the needle valve/seat stopping it shutting off, if it has been showing signs of leaking (running rich etc) then it might be the needle tip damaged (often viton rubber) or seat worn, in which case replace, but they are not particularly prone to failure really.

Obviously check the various hoses for splitting etc, that's not uncommon.

Edit - PS, avoid any sort of sealant when working with carbs, use the proper seals/O-rings/gaskets and they'll be fine, sealants rarely work and it just gets into the small passages and clogs jets etc. Nightmare.

*Pointless update*

Well after splashing petrol everywhere starting it on the choke I whopped the tank & air box off and peered at the hoses. There aren't many and they're all OK.

Then had a go at getting the carbs off and failed.
"...be aware they are a tight fit..."
No Kidding.

Hell it took me a while to deal with the "slide the choke cable out of the holder" :)

Got late and got bored and banged it all back together. Fired it up without choke and rode it home.
Basically it's stopped leaking but I'm guessing the float's are sticking/ over filling. So at some stage they ought to come off, get a clean.
Some stage after a new seal kit arrives as the float bowl seals don't look great.

next...
