I'm back after a very long and exhaustive struggle to get the part I needed.
I brought a new top end rebuild on eBay then after months, nothing arrived.
So I got in touch with eBay which was almost impossible as I'd brought the item as a guest on eBay. They told me to get in touch with Paypal so after a long, long while I got my money back. Then brought the same item from the only supplier her in New Zealand, then upon assembly I discovered the cylinder was defective - bore not big enough! So then had to wait for the replacement which I put on today.
Now its going again :>
Where should I go to get someone to help with carb jetting?
