has anyone used 1 of these if so what are they like , are they any good compared to the 'Petrol King' regulators ?
these just look easy to set up knowing what psi the carbs should be set at as these 1 are marked .

I have one on my car and it is that easy to setup - even though I was recommended to run the Blade engine on 1.5psi, and at that it was hesitating after giving it some, and changed it to 2psi and it has run fine!

I suspect that the people who have told me the 1.5psi setting are correct and that the regulator is a tad inaccurate, but I have no way of checking it???
