Free Bird et al,

Just got off the phone with Hank at Sonic Tronics. He indicated that our problems were as a result of not having enough amperage to drive all three cylinders. He said we should have 1000 mA for each cylinder and that was why my 2300 mA 4-cell was not enough to keep things hot. I am going to try a 4200 mA 4-cell that I have but it will be a couple days before I can report.

He also said that the only reason the 5-cell did not blow out a glow plug, besides being very lucky, was because I left part of the “servo wire” on the battery, which offered enough resistance to lower the 6 volts. Battery not being charged to maximum and only run at start and 1/3 or less throttle also helped.

Hope that helps, buying a new 3000mA or greater 4-cell battery is the cheapest of solutions so far presented. BTW, Hank invited anyone to call if they had more questions.
