Negotiated rush hour Aberdeen traffic and took the rib to Graham at Mackay Marine near the harbour. He sorted it within 3 hours. Timing was out and carbs needed adjusted. Happy to have this finally resolved, and engine is running sweet. Thanks for everyone's input.
Nice that You got it sorted, and that without any major repairs!

So, who played with the timing before it was sent to mechanic. How much did you payed to have it completely sorted out ? Whatever was charged was by worked hours or worked done ?
