I haven’t had the chance to use this yet. I bought it to replace the one I had. They work well finding TDC. It is easy to use.

Works like a flower pot should. The needle moves much more freely than the well-loved old unit I borrowed last year. The sparkplug-fitting timing plug is surprisingly well machined.

Good product. Doesn’t fit Cessna 172M prop spinner without modification. Still working on that.

Great product! Engine must be level (as if airplane is in flight)! Conventional gear airplanes will require the tail raised appropriately. Also, in case your wondering why you Must do the math correctly , it is because the engine stop plug is indiscriminately screwed into #1 cylinder (it is possible to use without the engine stop plug by determining exact top dead center with a screwdriver or socket extension), in which case , just set dial to TDC upon determining TDC on compression stroke!

Made timing much easier, especially on the old continentals where the timing marks line up on the bottom of the case. Would suggest putting a rag over spinner, the sharp aluminum left small scratches the first time I used it.

Works like a champ! Simple easy to use. Simple, easy to follow instructions come with it.

Another great easy to use product for what has always been a issue. Would be great (5 stars) if it came with two extra lugs to allow it to be used on a three bladed prop. Was easy to convert now mine does two and three bladed props real easy

If you’re a mechanic still using this old style timing device. I’ll go ahead and tell you. You will never get your magneto timing as close as I do. One guy suggested he could find top dead center with a screw driver. What an idiot. Not even considering how many degrees the crankshaft turns at that point where you can’t feel if it is going up or down. The engine books I have read say timing tolerance is +0-2 which means don’t time it further advanced than TCDS says and a wiggle room on the retard side. You can not get that precision with this device.
