Hi Nutloose
It’s an LAA type and certainly the wrong carb fitted, Nicholson McLaren overhauled the carb around 50 hours ago, the engine has recently had a top end overhaul and the rich mix has become more pronounced.
I’m surprised that it hasn’t been spotted before.
The a/c was built in 1970 as the demonstrator for the parts manufacturer “Thorp”
Thank you for the advice I will call N/M tomorrow, I note that Airpart may be an option although I won’t be exchanging like for like. The MA4 is for an O320 so may be more desirable.
