Had to make a hall sensor mount on a converted engine with a CH ignition box. Got it timed well and it seems to spark OK, but due to space limitations in the hub, the sensor is not exactly flat in reference to the pulse magnet. Maybe 10 to 12 degrees bent. Could this be a problem? Haven't ran it yet. Thanks, Paul

As long as it makes and breaks is all important

If the gap between the sensor and magnet is close enough , (no more than .030") it should work fine. If you start getting high speed misfiring though, you will have to close the gap some more. I have tried alot of sensors and some work in a leaned over attitude while others don't. It depends on the minimum gauss rating in the operating specs for the particular hall sensor.

Perhaps you can help. The engine starts around 1/4 throttle and runs and can excelerate however when you throttle back it dies when you go to idle. Changed the carburator and same problem. changed spark plugs same problem.Changed ignitions same problem. Any suggestions?

Have you gone thru the initial needle settings for both high and low needles?
Have you checked the reeds for proper seating if it uses them? If it has reeds, even a small air gap between the reed and reed block can cause loss of crankcase pressure and or vacuum, resulting in low volume of fuel being drawn in at low speeds, making the mixture too lean and subsequentially making the engine starving for fuel at an idle. There is a post in the forum here on a remedy and what to look for if that seems to be the problem.
