That's some excellent work Is the carburettor a commercial unit?

Which specific model no, I cannot tell, as there are a number of different choke diameters in the WY series.I have a WYK-33 fitted to my Honda GX32 tank engine and also to one of my Bristol Mercury engines. I think they are one of the best diaphragm carbs available. They run straight out of the box and I have never needed to touch the two factory set adjustment screws. The rotary barrel rotates and lifts when the throttle is opened, this lifts the needle to give more fuel as the revs increase. It does that rather well. I would recommend a WYK for any engine over about 20/ 25cc. They are dirt cheap on e-bayMike
If I could work that fast I’d have my models built in no time Seriously, a fantastic job. Well done!
