troy bilt surging

Is there anything else that would cause a snow blower engine to surge besides a dirty carburetor. Cracked fuel line? Cracked primer hose?
thanks

After is warms up does it go away? How old is it. Single stage or 2 stage. Brand of engine. Lots of different Troy Bilts have been made for many years. If it is almost new it is probably just that new blower engines are to lean especially when the engine hasn't warmed up. Roger

Doesn't go away after warm up. It is about 2 years old. It has a different engine, it is like a copy cat engine. I hear air when I am priming it and that seems odd would that cause it

Hearing air when priming might suggest a cracked hose.
You say a copy cat engine, is it ohc ?
Could be dirty carb. Do you have any history of it like if ethanol gas was used and left for how long?
All in all it suggests a thorough carb cleaning.

Snow Removal Apparatus I own:
Ariens ST1530DLE, and good ole arm powered scrapper.
The 15 HP is a new Ducar engine sold
by Princess Auto in Canada.

I think it is normal to hear air when priming. As for the surging that indicates it is starving for fuel. Could be the engine was just made that way for lower emissions, could be the carb is a little dirty or could be an air leak whether it be from a broken hose or a leaking gasket. Could be bad gas as well. It could be old or have some water in it.

Please direct all snow blower questions to the forums and not to me with PMs.

when buying any machine, ease of repair/maintenance is a factor, often overlooked. if the machine is a bear to work on, get 'er running again, sell it, find another with a better layout for maintenance, cuz snowblower carbs have to be cleaned often over lifetime of machine.

thanks guys, this is a big pain in the but to work on. It is a friend's snowblower, he asked me to tune it up for him. I do some repairs and tune ups on the side. The engine is definitely not a birggs, Tecumseh, Honda or Kohler, it must be a Powermore.

Got it running smoothly yesterday. I took the whole thing apart again and really went over the carburetor, probably used more than half a can of carb cleaner. I draind the fuel tank and blew it out as well as the fuel lines.
