Then it's not important to have a shielded power wire. The ignition noise can be getting into the radio on the power wire or on the antenna. One quick check is to have the engine running and disconnect the coaxial cable at the radio. If the noise goes away, it's coming in on the antenna. Then the only solution is to stop the noise at the source.

I remember the first time I fired up the VW on my last KR after rebuilding it, the wonderfull airplane noise sound, the feel of power as I increased the throttle, the wind off the prop, the thirty foot long oil slick on my neighbors hand manicured front lawn because I didn't tighten the oil filter. Good memories.

I have completed more tune-ups on aluminum head engines than I can remember, and never had a properly torqued plug back out. The secret is to use Permatex Antiseize on the plug threads, and install at the recommended 20 ft# of torque. Only if the threads are worn out, or some of the original threads have been pulled out by removing plugs in the past will you run into problems. To properly helicoil threads is alot of headache, aggravation, and possibility of getting metal into the engine if done with the heads installed. Protect and prevent, is better than repair. Colin : In fact the plug that was thrown was antisiezed, which as I understand it ( correct me if I am wrong), is to prevent seizing, which in my mind is the opposite of throwing a plug. I agree there is some effort to install( and I personally would not try to drill the plug holes with out removing the heads!), but in the building process the heads will be off at some point. I will install the heli coil on the thrown head now and do the other side later when I can use the opportunity to inspect the valves, seats, guides, pistons,rings, etc. and the cost to have a machinist install the heli coil is $10 a plug. Otherwise you have to buy a special tool kit which cost @ $200. In my misfortune I have been told by a half dozen machinist and VW experts that the plugs should be helicoiled or inserted with some type of thread strengthener.

I have a feeling that on a 6 cylinder distributor and coil powered unit the tach should be set to 6 pulses per revolution, the three pulses setting would be for a 6 cylinder coil pack setup where the plugs spark on the exhaust stroke as well a-la motorcycle CDI unit.

Looking good! It won't be long and you will be having days like I had today. Flying along above some puffy cumulus with a 30 mph tailwind making 190 ground speed heading to a flyin. I've managed to put 55 hours on my KR since the middle of February. I need to take it out of service long enough to finish the paint, trim, wheel pants, etc., but I'm having too much fun flying. Yesterday I had two Q-200's , one on each wing, in close formation (50 feet) and ended up making a high speed pass at 30 feet AGL with one tucked in tight on my right wing. YEE HAA............... Four place KR: I'm officially laying claim to having the first 4 place KR. My daughter is expecting twins in November and I took the three of them flying last weekend. Somebody pinch me, please.......

Typical four stroke engines (such as cars and Corvairs) spin twice for every time they fire (one TDC is for compression stroke, the next one is for exhaust stroke), so a Corvair six times per two revolutions, (averages firing three times per revolution), so I have it set correctly for my engine type. I hooked up my Karmann Ghia's tach to it today and ascertained that both EIS and Tiny Tach our way out in the weeds. The Tiny Tach reads about 5000 rpm at idle, about 7000 at 2000 rpm, and then it goes back down to 5000 at 3000 rpm! The EIS is off by some wierd integer number, but it fluctates so much it's hard to guess what it is. The Ghia tach got me through the day of testing though (yes, I know I have to multiply by .67), and I proved that it's putting out good power and with a good mixture. I also found out my oil cooler leaks.
