Hi dhanu76,
Welcome to RCI.
Looks like some tender loving care is required.
Besides the grungy looks, muffler bolts reveal possible thread stripping etc
I could restore it for you in two stages:
1. Cosmetic so it looks attractive to potential buyers
2. Get it to run properly, if the internals are in good condition
PM me if interested. I presume this is a 46.
Regards
I have a load of asp engine if you could help
