badcam..... ...there are 4-common runtime issues for the squarecan frontmount N-Engine. 1) runs for about 1-min and quits; bad condenser NOT yer stated problem 2) runs for about 5-mins and quits; clogged fuel filters (3 ea) NOT yer stated problem 3) runs for about 15-mins and quits, restarts in about 30 mins; gunked up ignition switch guttz NOT yer stated problem but could be 4) runs for about 1-hr and quits; restarts after overnite cooldown; sound like yer problem? BAD IGNITION COIL Yer OVERHEATING yer squarecan ignition coil and melting its insulative tars from too many amps caused by yer 1-wire alternator conversion. Yeah, I know yer partman said use a 12-volt coil; he is semi-right. Problem is the 12-volt coil was designed for 12.6 volts but yer 12-volt battery needs about 14.4 volts to charge the battery but the 1-wire alternator putts out 14.7-volts and that causes too much amps to flow and OVERHEATS the internal guttz and melts the insulative tars and shorts out some windings and whoops weak sparkies and quits running. But amazingly enuff, overnite cooldown solidifys the melted insulative tars and the coil will work just fine until it overheats again. (think candlewax) 10 years ago, the makers of the new squarecan 12-volt ignition coil used to include a little sheet of toiletpaper with instructions (but who reads instructions) in 6-different languages ('xcept 'muricum) to add an external additional current control resistor of about 0.047-ohms 20-watts (standard electronic value but NOT AUTOMOTIVE/TRACTOR part) RadioShack sells a 2-pack of 1-ohm 10-watt square ceramic resistors p/n: 271-130 that you can convert into a special "trick" 1/2-ohm resistor by twisting the wire pigtails together and use it inplace of the "infamous ballast resistor" to limit your 12-volt coil current and overheating. Understand?..... ...respectfully, Dell
