so whell on the no choke on running issue, had the motor out and checked it over stripped and re sealed everyt fin with new seals here n there
just thort id check the reed valve assembly and took the manifold off and it was wet thru all over with pre mix so it must of been that whats leaking, some ones cut the fins off and recon they have gone to far and sanded the sealing surface
so banged a nothewr one on un molested with some sealant, hopefully be sorted, will have it running sat again so hopefully sorted
