I have a super tigre 45 and having been wanting to buy a different manufacturer's carb for this engine. Please provide the details on the Perry carb. I have had 3 of the ST engines over a long period of time and have finally determined that they all are built the same and with the same problems. The money saved in buying one of these engines is quickly lost in frustration (I am a dead stick expert because of this engine). Hopefully,  the other carb is at a reasonable price. After much time of tinkering with this engine by myself and a few experts, it is beginning to become a reliable engine but it still does not idle right. I now tolerate a high idle and kill the engine by squeezing the fuel line. The high idle has occasionally caused me problems getting the plane to slow down enough for a good landing....Thanks
