I don't trust my gauges anymore. The cyinder head
temperature was only sitting around 200F, while the oil
temperature was 250F-275F. To be safe I just shut her down
and had a rest, I was not in a $2,500 hurry.

The thing I like about the Maxi-Cool oil coolers is that
they have a built in fan:

What do I need 1/2" or 5/8"?

I am not as mechanically inclined as I would like. What is
involved in setting my timing?

Thanks,
Chris

>Air-cooled engines and air cooled vans even more so are at
risk of damage from heat when the timing is off both to much
and to little. timing can over time hours not minutes cook
an aircooled engine. the fuel pressure incorrect air fuel
ratio, to high of a load, abient air and fan intake temps
also play a roll in engine temps. I highly recomend the oil
cooler set up from the bus boys to all my customers when
they purchase an air cooled type 2/4 engine from me. Oil
does not like to acept more heat above 225 F range so when
you see higher oil temps the head and piston temps are whats
driving the increase. my guess would be that you had head
temps in the 450 F range to make the oil that hot and that
you where going fast in the heat of the day
