Guys i have nrg mc3 lc i open it for water pump changing, i saw that my reeds was damage too and i buy new malossi. I Close the engine, the first 50km's the engine run good like before the opening but after that in high rpm's (after 8-9) or on full trottle it chokes.. i must give up half trottle to run to top speed or run normal.. i start to search for the problem, it's not from the gas or oil lines, its not the carburator mixture or transmission problem, can it be from the reeds? ideas?
could be...hold them up to a light or the sky and if you can see a crack between the reeds and the block try to replace them...sounds like a carb problem to me though
