I’ve got a couple of problems with my engine I rebuilt. It was removed so I could have my gearbox rebuilt. I rebuilt it as it was out of the car and I had discovered a small lip at the top of all the cylinders. This is normal I was by my engineer and it would be a good idea to have it re-honed whilst I had it out the car.
The engine has covered 60000 miles and is a standard 1275cc A+ from a 1993 Mayfair. Everything was running perfectly before removal. The following is the work I carried out:
- Re-honed block, standard pistons which came out of the engine with new rings
- Swiftune sw5 07 camshaft, oil pump and cam followers
- New cam bearings (fitted by engineer) machined to new swiftune camshaft
- New bearings, gaskets and seals throughout
- Standard cylinder head from engine, fitted with new exhaust valves (old ones were pitted so replaced), all valves re-lapped to seats
- New clutch kit fitted
- New plugs, leads, distributor cap
- Re built standard HIF38 carb
My problem is the car doesn’t run too good now. It will start fairly well with a bit of throttle from cold, warms up fine then once it gets fairly warm it begins to run rough, sometimes cutting out. If I take it for a drive, any time you put load on the engine it wants to die and will then cut out and will be really difficult to start (I.e. you have to crank it on the started motor for about 6-10 seconds to get it to start if your lucky) once its started, the engine hunts and struggles to keep running and eventually cuts out and I’m back to square 1.
I’ve replaced numerous parts and gone back on myself to check that I’ve put thing back correctly:
- Checked distributor drive positioning
- Cam timing
- Replaced ignition module
- Changed carburettor (to rebuilt HS4 with needle from HIF38 carb)
- Replaced coil
- Checked fuel pump for correct operation and split diaphragm (all ok)
- Tried using older ignition system (points and condenser) to eliminate electronic ignition fault
After replacing/checking the above parts I’m left with exactly the same problem. Having spent £100’s on the car re-building the engine and numerous other parts, forced to miss London to Brighton its beginning to get really frustrating and I’ve nearly taken a hammer to the car on few occasions.
Im just lost now and have been over so many things I’ve done to try sort it out with no luck. Obviously there’s something wrong but what? Can anyone out there help at all?
Any help at all would be most appreciated!

P.S. Sorry there’s so much to read through. Wanted to be as detailed as possible. If there’s anything else anyone needs to know just ask.
