Still clutching part 2

I bought a clutch kit for £39 from my trusty local motor factor and set aside a whole Sunday to do the job fitting it. I started at 11.30am and it was nearly 10pm when I'd finished! I was interrupted several times and bolts that refused to budge didn't help. Fitting the gearbox was a struggle so I enlisted another pair of hands to make it comply! Also I used my tap and die set to clean up the threads on the bolts. When I reassembled things I used copper grease to make things easier next time. Unfortunately, I've found another couple of problems along the way. An engine mount is broken so it is either raid my spare parts or buy a new one. The other problem appeared when I was road testing. The engine would lose power and cut out. A couple of minutes later the car would start up and run fine and then it would start hapenning again so that's another thing to sort out. I suspect a fuel problem as the ignition timing was set the previous week.
