thanks! i was wondering why i couldn't pedal. i looked (not too hard, though) for a "bike mode" switch, but found nothing. w/o holding down the decompression lever, the bike wouldn't move forward at all. and when it does, it always starts trying to engage (even after i release the lever). so that info will be good use.
the guy i bought it from told me a bit about that valve.i'm not sure how much he knew ... but he said that after you fill the tank, open that little valve to let the extra air out. maybe i should keep it half in half out? i've been tightening it back in most of the way. i'll fiddle w/ that and see what that does.
i have no idea on speed (though it seems to vary). the speedo cable is broken, so i'll have to get another. it does take a long time to warm up, though. after i rode it for a bit it wouldn't die at idle and also ito would seem to go a bit faster.
after i take the carb off tomorrow, i'll check if another dellorto carb will make a dif. i also have a full set of jets, so i can play w/ that. i don't have an extra carb per se (except for my 14.9) ... but i do have a dellorto 14.14 made specially for the carabela. i can try that out for a bit to see what it does.
i also put in a bosch platinum (of course!) and that seemed to do a bit of good. i also eventually want to fix the kickstand (a bit weak now) and the foot bar (needs a weld). the rest is great. mine even came w/ the toolkit! ;-)
tomorrow i test it on hills ...
