LML Gang,   Several of your posts have me nervous about this IV-P that I’m building.  Many times, we hear postings about the people having troubles but don’t hear the good stories.  I appreciate Michael piping in about his better luck with the TSIO-550.   Any more of you out there getting good life out of your TSIO-550 engines?   Thanks!   Dan Olsen Fort Collins, CO     <image001.gif> <image002.gif>

I have just over 1100TT on my factory new TSIO 550B- two cylinders hovering at 60 and the rest in the mid 60s. Just put 12 hours on it last week (LOP 16.5 GPH 28 inch by 2370RPM) and burned barely a quart and it runs smoother and smoother year by year. Most flying FL190-230. Hoping to get another couple hundred before topping it. Michael Smith
