Thanks for the info Dar i have not seen properly that horace mention about the 7mm carb inlet, about the the 165-170 degrees of exhaust timing i didn't know although i have one very old quickie which is brown color maybe it was black and from the use of a lot of years gone brown. But still runs perfectly, thats one of the greatest glow engines i ve ever seen. What it concerns me is that i have 2 new quickies with 9 mm carb inlet but the sleeve has about 155 degrees i will need to check it more carefully and if thats the case i will let MVVS to know maybe it was a mistake on the production of those 2.
