HIF44 on a 1098, wrong, right, or indifferent

Hi All,

Just after some opinions here and to check i've not done a no no.

The HIF38 carb i had on my 1098 was knackered, so whilst i'm building up motovation to refurb it, i found a hif44 in the shed, fitted it, and it seems to run lovely - and is giving me around 60 miles to 10 quids worth of fuel which doesn't seem terrible.

The only reason i'm questioning myself is due to a quick chat with the guys @ moss europe re an air filter for it - He was adamant that I should change the carb as it will overfuell ?

So should I get my backside in gear and rebuild the 38 or just be happy with the 44? will it cause any damage if I leave it?

Cheers

hahahahahahahahahahahaha - hohohohohohohoohohohohoh.......gaaaaaaassspspsppppppp.
Oh dear - all this crap about 'over fueling' - I hear it all the time on the Mini forum. Yes - the carb is slightly on the large size for your engine - but why on earth would it 'over fuel' (whatever that means)..... It's going well - and 60 miles for £10 doesn't sound too bad to me. (Well - it does really...... but not a lot we can do about the cost of fuel. these days.) Have a look at the plugs to check the colour. But no harm at all using that carb - this is the beauty of the SU design - the choke area adjusts automatically depending on the air flow demand from the engine. I dare say your carb piston probably never opens right up - but no matter! It's running well. What more could you ask!!!! :lol:

Thanks for that BMC, best get an air filter on it as running without one is probably not the best idea!

A pair of 38s might be over doing it a bit :) . The only problem with too large a carb is that it may not lift the piston fully on max acceleration and therefore not be working at max efficiency, but under normal conditions you should be ok. A knackered 38 versus a good 44, I know which I would fit
