Hard to start

[rightstuff]

honda cb600f 2 2002 903 miles drained out tank changed plugs removed carbs cleaned out main and slow RUNNING jet checked all floats looks a complicated block of carbs re fitted also fitted a new petcock and filter changed oil and filter when I do eventually get it started it runs fine ticks over nice revs up to max perfectly if I leave it till next day will fire up but then cuts out after a few seconds and will not start convinced problem is with carb am I missing anything is it worth me taking carbs off and having another go or leave it to honda to sort out is it worth getting carbs sonic cleaned could they do that as a block or would they have to be stripped right down any one know of a reliable place to do that in essex

are you using any choke? and does it make any difference with it on or off or even halfway?

[Ian Frog]

IMHO definitely worth sonic clean but can I suggest before you go to that expense I have had good results from immersion in a 50 50 mix of Coca Cola and diesel.

Please don't laugh and remember to thoroughly flush with petrol afterwards but you would be amazed at the crud this mix can shift after a couple of days.

Good luck.

Cheers

If it has a manual petrol tap try setting it to prime . If the problem goes away then it's either a stuck diaphragm or a kinked vacuum hose . 18 years old and 902 miles . This thing has been doing a lot of standing around . Where did you find it ?

I was with you right up to the " Coke and diesel " bit .

[skyrider]

i know a mechanic mate of mine sometimes soakes carbs in coke to clean them (have you ever seen what coke does to loose change ) makes you wonder what it does to your insides when you drink it

[Guest Richzx6r]

I hadn't heard of the coke/diesel mix method but may give it a go with the lawnmower carb as it's full of shite

[Tiggie]

I saw a video once of Coke being used to clean out an EGR valve and it worked so I can believe it will do the trick. Theres just something about introducing sugary water to engine parts I don't like

[skyrider]

just swill them out with clean petrol after

[Bender]

Coke cleans dpf's too.

weather's not to good tomorrow will get carbs off and give the coke a try nothing to loose will heat it up first

Ah ok , Coca cola . Good for cleaning aluminium but not so good for clearing obstructions from jets and airways . The active ingredient is Phosphoric Acid which is not kind to teeth . I should know, I've just had all mine rebuilt and my dentist told me that most of the damage was caused by my liking for Diet Coke .

use diet coke

[Ian Frog]

I am learning new stuff as well here.

Is Diet Coke better than the full fat stuff I have been using for years?
