Holy hot engine batman!!

Hi guys and girls,

I purchased a metro (previus owners word and the fact it's missing a bypass hose) 1275 that the previous owner said might be a 1293/1340, he really wasn't very sure. The engine was missing all ancilaries so I have used my 998 ones, it has 1 1/2 inch HS2 but I'm not sure what the dizzy is. The previous owner said the engine hadn't been run for about 10 years so I had the head off and gave it a serious clean and checked for bore wear etc. After much messing about the engine runs but only with the dizzy advanced quite a bit, which then results in overrun (quite a lot actually) and the engine being VERY hot despite the temp gauge reading normal. I fitted a needle I used to use on an old 1340 to try and give it a bit more fuelling but the problem remains.

The engine code is BH 12 0000001, which basically just denotes that it was a brand new unit and a 1275. It has a non verto clutch and the exhaust valves are 38 mm. That is all I can really tell you about the engine.

Sorry about waffling but I wanted to give the maximum chance of someone working out my problem.

Can anyone help?

Is the adv/retard sevo part of the dizzie working??

The best carbs for 1275s are hif 38 or 44

Hi Rob,

The dizzy is sound, I made sure I used parts that I knew were good.

Sadly at present I'm not in a postion to buy another carb

I belive I have a couple of 1275 metro carbs I'll dig them out tommrow night and drop them round on Wednesday evening if it's any use. Think I have 2 should be able to make one good one

Cheers mate!!

I'm sure that will help a lot!! Despite everything everyone has said to me I still think it's all because it's the wrong dizzy! Am I just being dense?

Curious. Metro 1275s normally have engine numbers starting 12H, and 29mm exhaust valves. If that was actually an inlet valve then it's about as big as they get, makes me wonder if you have a tuned lump. In which case goodness only knows what carb and dizzy you need.

Incidentally Metro ignition timing can be anything between 1 and 13 deg BTDC at 1500rpm, depending on the model.

The reason the engine code is odd is because BH denotes that it is a brand new unit bought direct from Roveron its own not fitted to a car and the 12 denotes 1275.
