to-20 project

Posted by cliffyboy on April 02, 2014 at 14:44:43 from (69.35.177.182):

hey guys.. started working on the to-20 i picked up for my dad, and have a couple questions. as to what i've done already: new points, condenser, plugs, dist cap, wires, rotor button. rebuilt carb (my first carb.. yay!). it has a rubber hose and in-line filter on it that i'll change, but seems to get enough gas thru it to run ok, and just got the sediment bowl today (didn't have one) and going to convert it to steel line but need to get more parts lol. checked air filter and sprayed brake cleaner down thru it until i can do some proper maintenance on it.

have not changed oil yet, but added a qt of 30 wt non detergent to get it further up the stick until i can get a filter and some oil.

ok all that said i pushed the starter button and it fired up on the first crank! made me feel good (especially since i'd never tore apart a carb or set points before lol). ok time for questions.

1. running it sounds what i'd consider "decent" but is blowing bluish smoke. it is mild at idle and increases with throttle. i assume it's oil of course. is there anything i can do to help with that? doing a rebuild is not financially an option right now but the itch to use the tractor is there lol. would oil/gas additives help? would i be doing any damage running it "as-is"?

2. i appear to be missing the compensator spring. i don't have a shop manual for it yet (need to order one, just haven't done it yet) and don't know what all the spring does but the only thing i've noticed is that the throttle doesn't hold position and i assume that's it's purpose. i see the arm it connects to, but where does the other end of the spring go? can't seem to find any pictures online to show me and don't see anything on the tractor.

3. does the throttle need a return spring? the only thing i can compare to is the 9n that i bought last fall (my first tractor), where as there is a spring on a linkage that when moving the lever to idle makes the rod push the throttle shaft back until the idle screw stops it (hopefully i'm using the right terminology). I don't see where there'd be a spring on the ferguson? it doesn't push all the way back to the screw when the tractor is off, but while running it seems to work (perhaps just the vibration allows it to). am i missing a spring for that?

i know a service manual would probably answer my questions, but 30 bucks makes it a luxury this week and i need to get "moneyed-up" a little bit before i order one (probably in a week or two) and i'd rather spend money on parts i need to get it running this week
