I've got an interesting problem with first and reverse gears on my Mk1 Eunos. When it's warmed up it's very difficult to engage 1st ie. at roundabouts and such and when it does go in the car begins to creep forward with the clutch fully depressed after a short while.It also becomes impossible to come out of the gear without switching off the engine. Exactly the same symptoms occur in reverse.
When I briefly mentioned the problem a few weeks ago M-m suggested changing the slave cylinder for a start. This has been done but with no improvement. I'm wondering if it could be the clutch plate but I'm only guessing. It's a nuisance but I can live with it if it means earth shattering decisions such as fresh gearbox but it would be interesting to get feedback on the problem.
M-m. I've tried a few times to email you but my internet connection is shi... not very good at present.
