Running problems, help needed - N/A 1275 HIF44
Turbo Mini Forums

Hello chaps

Firstly sorry that this is N/A related but I am looking for some help. I am in the early stages of converting my Nissan powered "67 to something more original (all be it turboed). I have sourced a complete 1275 N/A in a shell which I have bought for the engine, but I've hit a few problems.

Firstly I will start with the basics.

1275, originally from a metro I believe.
Electronic dizzy (with the two point plug)
HIF44 carb
K&N
LCB

Compression seems strong at 145-150 across the board at WOT.

I have checked the timing with a timing light, it appears to be that the TDC mark is level with the 2nd tooth down on the marker.

Fuelling seemed fine but to eradicate this I have gone for a simple gravity fed fuelling system as a temporary measure

The problem.

I was starting the car, choke out, it would start relatively well. Choke was depressed and the car would idle fine.

As soon as I gave the car the slightest bit of throttle it would bog out and die.

If I got the car to temperature at idle and pulled out the choke it would immediately die, this suggested to me it was running rich?

I checked the carb slide and dash pot oil, there was no oil and the slide was sticking, I cleaned the slide, spring and replaced with oil and cleaned out the float chamber but this made no difference.

After a bit of reading, especially on here I found that the mixture is set primarily by the screw near the fuel inlet and the idle screw? I then found some suggested base settings for the HIF44, I read 3 turns out and then work from there, Is this correct?

I looked at my carb the other night to find this screw was 6 1/2 turns out. I removed the carb, cleaned it, wound the carb to the suggested 3 turns and reinstalled it, the car now struggles to start and if it does it dies immediately.

Could anyone be kind enough to give me some ideas on where to start? I want to remove the engine as soon as possible and get my cooper in the garage but I am reluctant to remove the current 1275 until I have got it running half decent.

I am hoping I have supplied enough information and gone through the correct diagnosis methods.

Thanks in advance, Tomm
