Kevin H - that is a really nice 169. Really big question here - did you keep the balance gears in her so she "remains" original??? I don't recall if I posted a before shot of my 169 but will attach it below. Mine was 10 years in the making and from the pic you might know why.
Marty G - I get more and more impressed with the 128 with every pic. I especially like your attention to detail. Not alot of guys take the time to re-work all the nuts and bolts. What method did you use on them (or did you happen across a barrel of them in NOS, which are apparently around)??? I noticed the engine cylinder appears to be black, the remainder of the block yellow, and the head unpainted aluminum. Is this correct??? Did you paint the cylinder black??? I had a preference for the all black engine since seeing replacments in black. I had never seen one done in 2 or 3 colors as you have. It is sharp. I also like the little 70. I've kinda always wanted a similar 100 with those round fenders. Just can't find them out here in Seattle, but I got my son on the look bact in CT.
Ok, I'm gonna give away a secret here - on my painting. When it comes to the cast iron parts like the front axle and tranny, and for that matter the wheel weights, I have always just cleaned these up as best I could, high speed wire brush the rusty areas since it's almost always just a light surface rust, clean everything with mineral spirits, and then go straight to final paint colors using a chip brush. Generally 2 coats, maybe 3. If you work the paint at the right temp., sun, wind, etc., you will avoid runs (The Cub Cadet yellow is thicker right out of the can than the Case/IH Ironguard and won't run as easily so it's my preference, and then I use the Cub Cadet spray cans for the other parts, which do get a proper cleaning, priming, sandings and feathering depending on the cosmetic exposure. I hardly ever strip anything completely down, and never really liked sand blasting because it can make the metal brittle and cause it to crack). Of course the more units you restore the better you get at doing it. I had a 107 at a show in CT that several expert spray painters couldn't believe I had done with the method I describe. Yes, it can be done. May take alot of time, patience, re-work, etc. So if you don't have the big tools, like a sand blaster, compressor and spray booth, you can still do it. I can provide references if someone wants verification. I will also admit some of my units had more than 3 coats of final finish (as a result of sand paper, re-work, primer, wet sanding and feathering, to get the correct appearance). Come on guys, you can ALL do it. If it ain't right the 1st time, take the time to do it again. It's part of the fun, and will provide you many many many many years of enjoyment knowing what you did.
Frank C - your engine is at risk. I would advise against using it further until you tear into it and resolve the problem. If it is something with the balance gears, rework it correctly, or get it done. And please please please include the gears, or get to Dave Kirk and get his crank balance item which replaces the gears.
Kevin H - here's the way my 169 was when I started except I had removed and placed the engine in storage. The finished unit is in my profile.
