Brilliant! Just did the leak down test on my Flathead the other day. Tried to use my handy-crafted soup can lid with the firing order scribbled on it, but it kept falling off. This thing is perfect. If it was reversible with just the firing order on the back for TDC locations it would be perfecter. Still want one.
Would it still work if the valves were in a different sequence? For example, the Flathead is E-I-I-E-E-I-I-E across the bank of cylinders. I think the Y-block is too. But, what if the firing order is the same as a Flathead, but the valve sequence is like a small-block Ford? Just wondering...
I have to work on that too, but for sure It is possible to build a tool like this one for every engines
Hello all Flathead addict! Just want to let you know that tools are ready to ship now! Please send me an email to [email protected] to order Thanks for your support Peter PS: the ones that already paid, tools are on the way to them
The fireing order on a flathead is 15486372 just watch the valves on the companion cylinder. Two cylinders come to the top at the same time one compression one exhaust if you watch the exhaust valve close and the intake start to open that cylinder is close to TDC exhaust. The companion cylinder is close to TDC compression lifters on the base circle of the cam. Set the valves on the cylinder 1/2 way down the firing order. On a flat head watch 6 set 1 turn the engine and watch 3 set 5 and so on.
Sunbeam, you're right on. You do not necessarily need a special tool to impress onlookers - a pencil and a piece of paper with the right numbers does the same thing on any engine! I might just add to Sunbeam's a helpful hint: take the first four numbers of the firing order and write them down, then take the last four numbers and write them directly beneath the first four numbers. Study these numbers as vertical pairs: these are your companion piston positions. And as you complete the adjustments on each pair of valves, put a pencil line through the cylinder number you've just completed. Rotate crankshaft 1/4 turn to set the next cylinder's valves in the firing order, and so on through the remaining cylinders. All it is, is just common sense. Or maybe sense is not so common any more. Learned this from Jimmy Binks, a premier racing engine builder in the Niagara region in the '60s and '70s.
