  1. I had chat with Model Shop Leeds before I brought the new low oil blend which I shared with Ron. All the Low oil content 'Laser 05 Pro' that MSLeeds have in stock is the new pinky/red colour using the new 7% recipe. Then as Jon said the standard full oil content wont turn pink/red until Opi have used up all the ML70 oil they have. Also worth noting you now get a full 5 litres not 4.55 Excellent service from MSLeeds.

  2. Hi Jon

    Many thanks, that does make total sense. One of my Lasers 70s had been behaving erratically when applying power, 95% of the time it was fine, but then suddenly it would stop. I knew it wasn’t the tank position and plumbing as nothing had changed in 2 years and it was the first thing I checked over.  It had always been 100% reliable until now it wasn’t!  No fuel filters on the model, but two plastic housed filters on the fuel caddy. When I opened the main assembly (as in my photo) it had a few bits of what looked like tiny shards of plastic, no idea how it got there, but I think it was enough to occasionally interrupt the smooth flow of fuel.  I have done two flights since the clean and its 100% again.

     

  3. Hi Jon

    On the Laser70 carb is all the fuel metered by the main throttle asembly? i.e. does all the fuel go through thoses two small holes or does an amount bypass the main needle via the outer chamber and go down the spray bar to the idle needle?

    I ask, because if all the fuel is metered by the main needle why isn't the idle mix also affected when I set the main needle?

    Just curious
