I have only had my '79 Bay for about 6 weeks. The engine has good compression, but is leaking like a sieve! The carbs need an overhaul too as they are leaking a bit & the throttle spindle is worn. Needs setting up & tuning once sorted as its popping downhill & running rich. This is all going to be done in the next 10 days. She starts up fine after 4-5 cranks on the starter, EXCEPT just after I've filled up with petrol. It then sounds like the starter is stuck/battery flat, slowly turning over, then usually (twice in 6 weeks I've had to bump it) it fires up. After that its fine again until I fill it up with petrol again. Any ideas?
