I'm trying to take apart my carbs which appear to have not been used for a long time. They're in a very sorry state.

My current biggest problem is that I can't remove the float pin so that I can take the float off. The eagle-eyed will spot at least 2 other problems but I'm less worried about them right now.

The service manual and Haynes manual just say 'remove the pin' - as if it's that easy!

Looking at the picture below, there isn't enough pin on the left side to grip and there's no room to get anything in to grip it on the right side. I can't drift it out from the right side because there's a brass fitting in the way.

Am I missing something obvious? Can the brass fitting be removed? Its there some other solution?

Thank you in advance.

 

Hey there.
that brass post doesn’t remove. You have to slide the pin out from the other end.
it shouldn’t be bent like it appears to be. That may be a bugger for you.

 

Are you replacing the float?

If so, can you carve the float off the pin and then use pliers on the exposed shaft?

 

Replacing the float is definitely an option but I’ve taken a look at the next carb along and it seems to also be stuck.

These carbs are in poor condition and will take a fair few new parts to get back into good condition. I’m trying to decide between a full rebuild of these carbs Vs buying a set from a running bike (according to the seller!).

I bought the bike as a non runner and there’s a danger it could become a money pit. I don’t know how many problems I’m going to uncover.

Its a dilemma!

 

Just to be clear, my preference is to reuse these carbs. But there reaches a point where they will need so many replacment parts that I’d rather risk a set of second hand ‘running’ carbs.

On a related subject, does anyone have personal experience of the cheap carb rebuild kits on AliExpress (and similar)?

 

Unfortunately, when it comes to rebuild kits, you most definitely get what you pay for. Having said that, @IDoDirt has a somewhere in this forum for a really good rebuild kit that isn't astronomical in price. Looking at the pics, you will need a jet kit too, which is separate.

 

Thanks - yes, I suspected there’s no such thing as a true bargain from AliExpress.

You’re right - I’m definitely in for some jets! Hoping the other carbs might not all be quite as bad and that I could get away with only a couple of jets . But we’ll see. My plan is to get this carb stripped down before even thinking about the rest.

 

Try ultrasonic soak for couple days. Might remove enough corrosion to slide that pin out.

 

Oh dude get another set, If you're like me and don't have money to throw around then a **** set of corroded carbs are far more trouble than they're worth..

Unless you have a big ultrasound cleaner or have a buddy with one then that's gonna be at least £80, then there's the new float that looks as if its melted, rebuild kits arent cheap, snapped idle jet and the general state of these carbs.

I have tried this approach before and they are just on and off the damn bike so many times you will be pulling your hair out, trust me... at a guess you would be putting down almost £200 anyway!

You can get a decent set from a breaker or parts you can put together for possibly sub £100, ebay, facache marketplace etc.

Just my two cents!

Sorry - I never put the conclusion up on this thread.

I did replace them from another bike that, I was told, was running only a few weeks earlier. Upon arrival, I checked inside and they looked OK. Just did a bit of cleaning of the slides as they felt a little rough. Put them on the bike and, after sorting out a fuel pump problem that I subsequently found, the bike is running very nicely.
