rebuilt carb

[Whipper Snapper]

So I was out driving my tractor and it started to get all herky jerky and kept dying. I pulled the fuel line off and discovered that the interior of the fuel line had sluffed off and got stuck in the carb fuel inlet valve. I figured that since I had the carb off I might as well put the rebuild kit I had to good use. After sitting at the kitchen table last night rebuilding it I went to the auto parts store this morning and got new fuel line. Now I can"t seem to get the dang thing started. It is backfiring through the exhaust and also teh carb. I mean good two inch flames coming ut of the carb periodically but still won"t start. I have the valves set to the factroy recommended one turn cc. I am thinking of pulling out the spark plugs cuz maybe I fouled them? I think it may also be possible that there is additional debris in the fuel intake, I am just not too sure. Any suggestions would be appreciated.

What type of gas are you using and you dont have a meal line? They are an filter in top of the carb where the line comes into the carb. Have you clean this filter.

Sounds like you are using a rubber gas line. Not a good idea (think close to manifold). Metal fuel lines are available right here at YT. There is a filter in the elbow of the carb. Did you check it. Remove the pipe plug at the bottom of the carb and catch the gas - should be a pint or so in 2 min. If not you have an obstruction in the fuel line. Also check your firing order. 1, 2, 4, 3.

Is copper tubing acceptable for fuel line?

You said that you have the valves set at "recomended 2 turns cc",what kind of tractor do you have?All "n"tractors that I've heard of need a feeler to set the valves.---lha

Copper is brittle and will crack. Steel (brake
lines) work.

Didn't someone mention the possibility of electrolysis occurring between copper fuel lines and the steel fuel tank before? I thought I read a post here once saying that copper lines can result in a 'sacrificial' tank?

Someone correct me if I'm wrong, but I know it made me go out and buy a steel brake line.

Mine has been copper for 6-7 yrs..Don"t know of any problem. Some folks won"t use copper because it wiggles and bends so they say and stretches-steel don"t, so they say.

Mine has been copper for over 20 years....

Might be time for a "cool change".

Seems copper would be ok isolated from steel, and its more flexible, and less rusty.

Copper is not used as original equipment because the copper is prone to stress fractures and cracks because of the vibration it is subject to. You might think copper is O.K., but when that line cracks open and allows gasoline to come in contact with the HOT engine surface, your frugality will leave you with nothing but a charred, melted down and somewhat crispy looking little Ford tractor. Hopefully the tractor is not parked in the machine shed when this happens.
