I have yet to see any Top 80 get even close to running the max
Smaller ties could be used but they are likely to break which is why the 4.5mm ties should be used. Finally, a burned exhaust valve can increase EGT if it allows some of the ultra-hot gas during peak-temperature phase of the power stroke to leak past the valve and impinge on the EGT sensor probe located a few inches beyond the cylinders exhaust port. Millions of air-cooled VW cars got by with just oil pressure, oil temperature, and generator/alternator warning lights and little else. This causes ppto occur later and CHT to decrease. In this case, the overheating was caused by fuel starvation from a clogged
Road. Leave the old CHT in and add the JPI. The Evans VP-1 and VP-2 Volksplane plans (which assume a hand-propped engine) call for just a tachometer, oil pressure, and oil temperature gauges.
