Busy recommissioning a Greeves Scottish which I have just acquired. The bike has not been used in a while and the engine is an unknown quantity. I have tried to start the bike but only on a couple of occasions has it fired , ran at high revs but failed to respond to the throttle and died. I am now working through the easiest options first
Points checked and look fine - gap is 20thou. We advanced the timing a tad and she started to kick back so she is back to the original position which someone has previously marked with a pencil.
Bike has plenty of compression and easily locks up the back wheel when bumped.
Crankcase has been vented
Carb looks clean and is currently being ultasounded
Coil and condenser are under the tank and look new. Should the condenser body be earthed as it is currently just taped onto the top tube ?
New plug and new HT lead obtained and about to be fitted. Spark was initially weak but we did get an improvement by resetting the gap.
Should the rotar be re magnitised ?
Tank to be filled with fresh petrol
If all the above is done and it still fails to start I am thinking it must be the crankcase oil seals. This is my query. How easy or difficult is it to replace them. A pair seems to be under £10 but I am not sure of my competency and I do not have any easily understood workshop instructions. I would assess my mechanical skills as adequate for engine maintenance be it car or bike including changing brake competents. I have no problem in cosmetic refurbishment including full stripdowns and rebuilding but not major engine work [I can decoke and replace rings, clutch plates etc]
Any suggestions would be welcomed
