I baught a carb (HIF38) of mini93 and it was running fine on my car and his.

Than he borowed it of me (un-willingly) and whilst it was on his car his engine died.
now i have got my carb back and it is screwed.

It idles really well, but if you acclerate or rev the engine then the engine stalls, unless you floor it, and if you do it pisses out smoke.

What the hell is wrong with it?


Thanks.

P.S. mini93 also threw up LOADS on my bed and all over my mums favourate rug, Cheers.

what sort of smoke is it chucking out?

[mini93]

oie there was no need to bring up the sickness

No carb will run identical on two different engines. Thats what we have rolling roads for.

it was running spot on about 3 weeks ago. nothing has changed on it.

The smoke is just a dark blue, looks like burning oil, i dont think the two are connected.

i think he ment it worked well on my car before he swapped it onto his mini, he did have it set up when it was 1st put on his car i then borrowed it and put it on my mini (not set up) and it ran but extreamly badly on the way home on the motorway sumin died on my car...i didnt touch the carb and now its gone all fap on his engine

It hasnt been modified since it was on my engine, but it now doesnt work.

I cant afford a new one either!

air leak?

dash pot oil?

air leak?

dash pot oil?

I've checked the dash pot oil and it is fine.

I did not change the gaskets on the carb because they looked ok, could this mean that it is an ari leak?

I'm not sure, if they've not been apart then its unlikely.

Have you tried adjusting it? Or setting it up - you could go to a garage and ask them to look at it...

But if nothings changed I can't see why there'd be a problem, split fuel pipe?

Smoke from the exhaust I presume, sure it's the carb? 'Could' be spark plugs or leads giving up and your getting a missfire on one cylinder, build up of unburnt fuel then as you 'floor ot' this ignites in the exhaust = smoke and a bang...

I have checked my ignition and that is fine, i dont think the smoke is related to the carb.

I am not going to try and set the carb up as it was running fine befor it was removed and i waould rather not touch it before i can have a good look at it.

all my fule lines are brand new, the carb was doing the same thing on mini93's car as well so it is deffinatly a carb problem.

I'm out of ideas, can you find another carb and run that?

Or can you find someone close by to look at it? Where abouts are you?

Maybe you poured oil down into the manifold when filling up dash pot? Maybe it will burn off it you let it run for a while?

go and buy some carb cleaner.

spray it all out and give it a clean, it wont change the settings.

but first, get a can of wd40 (or use the carb cleaner) and spray it around where gaskets etc are when its running at idle.

if the revs drop and/or it stalls, this means you have an air leak

i remember when i stripped my bike, this happened, turned out to be a blocked main jet, but then su's are completely different

[fikus01]

check the breather pipes too!! they must be plumbed in or the carb inlet must be blocked off or it'll run ruff!!
