okay folks it's spring time in the US. If you have any openings in your engine compartment, beware that a bird can completely fill your fan with crap in a matter of days. For years people have debated on how crappy VDO guages are, due to them being cheap and innaccurate. i have installed vdo CHT guages in my aircooleds for many years, and have had several times i was glad i did...today was one of those. left my home and within about five miles *both* cylinder heads(i run two CHT guages, one each on #1 and #3) were at 400 degrees F and climbing....assuming that both of my carbs hadn't gone way lean suddenly i immediately thought of cooling problems(duh), no alt light so assuming my idiot bulb had not burned out(was a good assumption since the volt guage showed my alt was charging) that would mean the belt was still attatched, so i had a bright idea...pulled the lever for the heat to see if possibly the fan had come loose from the alt shaft....it was apparent real quick what had happened when grass clippings BLEW OUT of my defrost vents....i pulled over(all this happened quickly, temp gauges at this time were just a shade over 400F) and proceded to pull what seemed like enough grass to fill a five gallon bucket from my fan....sweet...now i get to pull the shroud to clean the crap out of the fan, shroud, cylinder and head fins, and also get the joy of pulling heater boxes to get the crap out of them and to blow it all out of the heater channel tubes....yeeeehawwww for me....make sure your engine compartment is sealed folks, and if you have guages, watch em....
