Im having some trouble with my C. It doesn't want to seem to run right. (1) When tring to start the tractor, it wants to start but it just makes pop sound out the exhaust pipe and the starter over runs the ring gear and spins.
(2) When tring to get it to idle it will sit there and spit and sputter and then it will cut off on its own.
(3) When going up a small slope the tractor sounds like it is going out of power and acts like it is going to stall.
I have timed the engine like it says in the owners manual. Please help me out if you can. Just cant quite get it right.
Thanks ERIC

check the points set to.020 adjust valves. .010 intake .012 extaust.also when trying to start give it a little more throttle.

--easiest thing to do first is take the gas line off the carb and make sure it has good flow. normally take off the sediment bowl from tank, flush out the tank, clean the screen, take bowl off carb and clean out the crud.
--second thing is to check the timing, but you think you got that? i think your mag should fire when crank is at the TDC point. you will get advance to the FIRE mark after it is running.
--after gas and timing, the last thing is spark. i would spend $25 and get a new set of copper spark plug wires and set of Auto 295 plugs. talk to STEVE at B&B if you cant find local.
--one last thing, if it runs o.k. whn cold and then has troubles when hot, you should consider valve clearance to tight, or coil in the mag starting to break down. this is if it is o.k. when cold.

Steve,

You say that I should time it with the TDC mark. I have been timing it with the FIRE mark because thats what the book says. Is the book wrong?
The way I have been doing it was turning the motor over till the FIRE mark was in the center of the hole. Then I would take the governor assem. apart and then take the magneto and turn it to the #1 sparkplug wire. Then I would turn the governor gear to match up with the magneto. Am I not doing this right? I think I am but I dont understand why the boook would tell me one way and you would tell me to put it on TDC?
Please respond!
ERIC

You are correct on using the firemark, But you need the rotor pointing at the TIMING LUG inside the mag body not #1 spark plug see illistration on the following website. just copy and paste into your URL window on your web browser.

Hope this helps
