So I dragged the old bolens out of the barn with my 9 year old son steering it - blew off all the cobwebs and rat poop and started working on it - flushed out fuel tank, replaced fuel line - removed carb to clean then put it all back together. Gave it a shot of starting fluid and she fired right up.....but, only until the starting fluid ran out - removed drain plug at bottom of fuel getting into carb. Removed carb and re-cleaned but, by blowing into fuel line inlet I can tell the float is not dropping down or something is stopping it or the fuel inlet when the carb is assembled. When I remove the bottom of the carb I can easily blow through the fuel line - something is jamming the float in the carb? Cant work that one out. Any suggestions?

Also, I am sure it will run by starting it with the pull start on the front pulley - however, can you see from the wiring I took a picture of what they did to bypass this? Can you tell me where the two wires go - also, it is possible to get a wiring harness for this tractor and, I bet the relay/solenoid is probably no good as it looks very rusted.

Here are pics:

Fresh out the barn!!

Engine pic

Can anyone tell where the two wires are supposed to go? I will probably re-wire the thing anyway. Also, where is the starter on this tractor? Cannot see it anywhere!!!

OK - this is NOT my barn - this is my father in laws so please excuse the mess - is this a sprayer for this tractor:

Thank you,

Hi Again
PTO Belt replacement
1. Pull the dtive belt tightner pully out releasing the belt and secure it to the frame.
2. remove the drivr belt from the upper pully
and let it hang down.
3. remove the pto belt and pullit up past
the engine pully.
4. quickly install new belt in reverse order
before getting a beer and forgetting how
you got the thing off (oops sorry, thats my
problem, not yours!)

Remove carb,check that tang on float not worn or bent/twisted causing float to go off center & bind against venturi(center tube) on carb body & bowl,remove float needle & check that needle & seat not gummed up,causing needle to stick.I agree with beau,eng had a starter/gen setup,both blk & red wire went to regulator & sol for armature on s/g,I am at a loss,as to how eng being stopped,same has either point/mag or solid state ign,only way I can see eng was stopped is to pull plug wire,ground kill lead at eng or pull choke & flood eng.

Thank you for all your comments - after taking the carb apart and giving it a good clean I put it all back together, checked fuel flow from bottom of carb, wound up the rope on the front pulley and it fired right up!!!!

Bob - you were right.....and, after getting it going I could not work out for a while why it would not go when I put it into gear and released clutch - then discovered that pin on rear right wheel needed to be pushed in to engage drive to wheel - a bit screeechy at first but off she went! I changed out the oil but left rear transmission oil alone as it looked full and in good condition.

I need to replace the belt on the pto drive at the front of the tractor....can anyone here tell me in fairly simple terms how to do this? I am planning on leaving the main drive on high as it seems to have enough oomph as it is.

It starts so well from the pull rope that I am not going to bother with the other wiring - I am actually thinking of turning the battery area into a small tool storage area.

Hi There
Will try and answer a couple questions.
1. Starter/Generator..mounts on lower left side
of engine on a bracket bolted to engine block.
(both are missing)
2. Wiring harness.. a lot is missing along
with the voltsge regulator ( looks like one from a 50's era auto) the red wire from the switch
may go to the engine points (grounds them to
stop motor) or went to starter solenoid- trace
Note : if you pushed it from the barn, then
the drive pin (left rear wheel-seen from front
of tractor) has been pulled . its on the drive
hub by the wheel hub.must be in for move under power with engine.
3. Card bowl may have a flat spot or tapered
one, if so this must be aligned correctly when the bowl is placed on the card or the float may jam.. don't know what carb type so guessing on this one
some good folk on the bolens groups over on yahoo
great old tractors -got 4 of em

There's a pulley on the front for a starter/generator but I can't see the holes where it would attach to the block on the picture of the left side of the tractor.I see there is an amp gauge on the dash so there should be a starter/generator.Those wires would probable hook up to a regulator.
