Could you try to little bit more explain what means "re built the engine" ? If you could make some video and put it on youtube to show us the strange cracking sound ? Which engine exactly do you have ?

Its no cracking i mean cranking/turning over it the starter motor wont spin enough to start the engine and i have had to rebuild the bottom end as it blew on a track now she wont start but she try's to its really annoying as its been off the road for a year now

If the starter motor spins slower than it have to (looks like have not enough power to rotate the engine) and there is a new and fully charged battery .. it will be possible problem with the starter motor itself probably. From my experience there is almost only one thing which can cause it as it is an consumables - carbon brushes ... and when using it anyway long time then carbon brushes could damage commutator as well caused by an electric arc. You can disassemble it and look in which condition it is. Depends on that you can change just carbon brushes or replace whole the starter motor.

I attached a video about servicing / rebuild starter motor ... they told there that it could be in some cases enough just only to cleanup it.

Anyway you can try to contact Ginetta ... they have email there and phone +44 (0)8452 10 50 50.

Servicing/rebuild your starter motor  |  More info

When most starters quit, they only need a clean-up of water or oil ingression and carbon dust deposits, their brushes and commutators are within specifications.

New starters cost hundreds $ and any parts could be hard to find. Servicing them with a bit of creativity could save you some money. Brushes could be somehow extended but the commutator segments have to be long enough. Brushes could be as short as 5.5mm not 55mm, my slip.

Do maintain electrical separation between the baseplate + housing + 2 bare wired brushes (ground side) and cable terminal + 2 insulated brushes + armature coil (battery positive terminal side).

Total service time on this starter: 1 hr
