Bruce, Steve- it ain't just the brain, but I won't go there...
Neil- there IS an informal hazing process here- it's called Digger and Bryan... if you've been RTFM'd by 'em, consider yourself hazed... and if they do it to 'ya AFTER you've read, consider yourself KNIGHTED! +<
Zach- Yes, condensers CAN go bad with age- they're a type of electrolytic capacitor, so they can dry out... they also develop internal leakage, shorts, broken leads, or in my most recent perplexation, the inner circumference of the clamp can harbor enough corrosion to cause the condenser to not have good ground contact, hence, not work worth $#it. BTW- don't call me "Mr.". I hate ties. I don't even let my students call me 'Mister'. Call me anything else you want, but just make sure you're smilin' when you say it. :-}
Norm- if I understand 'em correctly, the Command V's that're advertised as 'replacements' for the 6-7-982's ARE drop-in replacements... besides having a volumnous hood and side-covers, the x82's have lower frame rails on the sides, and Cubs tend to use a pan-base bolt pattern that isn't 'the same' as other (green, blue, etc) garden tractors, however, the one I saw advertised a day-or-three ago even came with a drilling template and the front-drive flange to match it up. Don't doubt those iron-sleeve aluminum V's with overhead valves... they're more than up-to-the-task, especially with full pressure lubrication and FILTER. I put a 15.5hp B&S Intek on my Dixon ZTR, and it's fantastic. IIRC The Command V is a tad heavier than a K-single, but probably a tad lighter than a KT, and definately lighter than the Onan 19... but I think it has 'em all beat in terms of power, smoothness, and noise.
