Strykass, there's nothing wrong with the MDS .58 or MDS .68. Pay for postage and I'll lend you a MDS .58 long enough for you to realize its a good engine. Its one of my favorite brands and I'll keep buying 'em cuz people are offloading them cheap.

Don't knock the engine unless you try it yourself. The same applies for other engines that are supposedly hard to tune. I have an ASP .91 readhead that supposedly could not be tuned and had a bad reputation. Other engines in same catetory were the Royal 46, Leo .46, ASP XL engines etc..etc... Never had a problem with any of them though you can find hundreds of complaints online.
