HIF 44 Carb

[GeorgeHurst]

Hi there,

I'm in the process of accumulating parts to tune my 1098 along the following lines: 940 head, HIF38 carb, LCB and freeflow exhaust. I have come across a cheap HIF 44 carb - does anyone know if this would be ok in place of the HIF 38, are there any advantages/disadvantages to using an HIF44 instead?

I have an alloy inlet from a Metro which I believe accepts both the 44 and 38.

Any thoughts appreciated.

Cheers,
George

I think a 44 is too big for a 1098 so I would go for a 38. Even though either will fit the MG manifold to size of inlet is matched for a 44 carb so you may have problems if using a 38 carb on the MG inlet. There are the correct manifolds for 38's available so I would find one of those too. All that said, there is no reason why you can't run a 44 on the 1098 - It will work, its just that I don't think it is optimum for that engine.

Thanks for that PSL.
Anyone else have any experience of running a 44 on a 1098 - good / bad?

A 1.5 in/38 mm carb is big enough for a standard 1098 engine, being suitable for an engine of 250 - 400cc per cylinder. Anything bigger will not be working at full efficiency and performance will suffer.

Thanks Mike. Was just hoping to save a few pennies! Will have to pay a bit more and go for the 38 in that case.
Thanks chaps,
George

It will work ok - and a useful thing to have when you finally upgrade to a 1275 engine. BUY IT! Either carb works fine on the MG manifold - small carb on big hole is fine - no problem there, if using the 44 - Vizard details how to improve matters by enlarging the inlet hole in the manifold to the MAX - and then working on the black plastic spacer to get a better flow from the carb into the manifold.

Thanks Roy, will get Vizard out in a minute and have a read and a think

If the price is right - buy it. It will work fine!
