![]() PS: Back in the day I didn't always have the money for things like a fully degreed balancer.and with the AMC/AMX that was almost something that could not be bought at any price. You can use the factory timing tab to interpolate to every 2 degrees. Not exact, but close enough for most of us. Was very easy after that to check timing with a regular type light. Filled each dimple with a different color hobby paint (white.blue/red/yellow). Balancer was off the car for timing chain replacement, so it was fairly easy to do. 1 TIMINg LIgHTS CP7529 Digital Timing Light Advanced features with a bright LED screen and mode indicator lights. Many (many) years ago I used a 1/8 inch drill bit and dimpled my AMX balancer as described above. That allows you to get very close with a regular timing light or with a "dial back" on zero advance mark. Mark balancer with masking tape and ink pen or ? to go from 0 to 40 degrees in intervals of 10 degrees. Then divide that by 36 to get the distance for 10 degrees. You can use a piece of masking tape and get the exact circumference of your balancer. I can do at 10 degrees BTDC because of the factory timing tab/mark, but how about others? The Actron was the brightest, and the Equus the dimmest.Īlways a good idea to check the "dial back". If you need help measuring the centrifugal advance, or vacuum advance, it will come useful to you. Speaking of the CP7527 inductive timing light from Actron, it’s super-simple to use and adjust the initial timing on any 2-stroke engine. Both fired at zero, and worked fine at all RPMs. Hence, buying a Timing light from such a brand won’t be a bad decision at all. ![]() An older Craftsman Inductive pickup, and a cheap Equus Inductive pickup unit. I also tested my other 2 timing lights at the same time (both non "advance" type). of error is not a lot, it still can matter. would actually be 30 crank deg.Īctron set at 62 deg. would actually be 10 crank deg.Īctron set at 32 deg. In each case, if I added 2 degrees to the Actron setting as a correction factor, it would fire at the correct point.Īctron set at 12 deg. (48 crank).Īctron set on 60, Sun read 29 dist. From LED readouts to swiveling heads, our timing lights offer the features you need to dial in ignition timing quickly and accurately. (38 crank).Īctron set on 50, Sun read 24 dist. (28 crank).Īctron set on 40, Sun read 19 dist. (18 crank).Īctron set on 30, Sun read 14 dist. (8 crank).Īctron set on 20, Sun read 9 dist. When the Actron's advance dial was set on "0", Sun agreed "0".Īctron set on 10, Sun read 4 dist. In other words, 2 separate sets of tests. The Actron readings showed a consistent 2 degrees of error at all positions above zero, as tested both 500 & 1000 dist. I compared it's readings with a distributor on my Sun Machine, to check it's accuracy (firing a separate ignition coil to fire the Actron strobe/circuit). I have an Actron CP7528 (Inductive pickup with the advance dial). ![]() Beware that the adjustable advance lights are not necessarily accurate.
