Makes sense- it's a solvent, and on an old carb'd vehicle, it would  
help with the gunk in the intake manifold.

I ran an old chainsaw (something that had been 'written off', and old  
as in "older than I am") at home off what might have been somewhere  
between 1/4 and 1/8th mix.

Nursing it along with the choke, I found after both runs a wet sooty  
slime on the case of the chainsaw around the muffler.  Looks like it  
barfed up quite a bit of carbon soot.  Mixture adjustments are way  
off, but once I have those figured out, I think it'll run better.   
Noticeable improvement in the amount of carbon on the spark plug,  
piston head, and from what little I could see of the exhaust/intake  
ports.  Rings look kinda shot though...I also don't think they're  
supposed to puff smoke out the carb :-)
