Had our KT-3 out to our cabin last weekend for the maiden voyage. Ran pretty good but the engine seemed to get very hot. Any ideas?

Hi Mark,

Did it get hot when pulling a hill or all the time? Many Kristi owners report having to stop after climbing a big/long hill. I see you don't have an oil temp gauge, you might consider adding one to monitor oil temps.

You might try fattening the fuel mixture up a bit and run it a little rich, this should keep the temps down. What elevation is your carb jetted for and what elevation were you at?

Chris

Hi Chris, The trip in is basically uphill for 5 miles, in places 6 to 7% grade. It got somewhat hot even on the trip down. I do have an oil temp gauge but is currently not working. I'm not sure on the carb jetting, cabin is at 8500 ft. This kristi has apparently been in CO it's entire life so I would think that it is set for altitude, but who knows. I was also getting what I would call some oil blowby off the tube next to the oil fill.

Hi Mark,

Yes, your Kristi was originally sold to the Colorado State Patrol, so it was used at high elevations. You will still need to jet the carb for the appropriate elevation. Talk to your mechanic and find an air-cooled VW guru for help in jetting the carb.

What is the condition of the rest of the tune? plugs? wires? oil? Old/dirty oil can really hurt the performance and durability of the air cooled VW engines.

Your engine was originally a 12volt VW engine with the serial number 118323. The original record remarks list the engine as 40HP Engine new heads on cylinders. Can you tell if it is the original engine?

Get the oil temp gauge working before your next trip out.

Hi Chris, Yes that is the serial #'s on the engine. My understanding of VW's is that on the bottom of the engine is an oil screen that replaces the oil filter. Does that screen need to be cleaned and if so how in the hell do you get to it?

Hi Mark,

The strainer is in the oil pan at the bottom of the engine. The only way to get to it is by pulling the motor unless you have really small arms. The filter system has always been a problem with the air-cooled VWs.

I know of at least one Kristi that had an aftermarket oil filter on it. Many of the VW magazine vendors offer this filter setup as something to purchase. If you plan on going to something with a filter, an external cooler outside the dog house should also be considered.
