ms660 surging

[lone wolf]

replaced the fuel lines, and it improved the surging a bunch, not smooth, but the surges are less, ill vac/pressure test it next, just wanted to update

didnt vac test it, but i found that the little gas line that goes into the carb, its got barbed fittings on both ends, is very finicky about its placement. the way it was positioned it was kinking. after repositioning, its not kinking anymore, and the saw surging is gone, sounds good now both in and out of the cut. thanks for all the help guys!

Sounds like the culprit alright. You mean the impulse line?

its the line that feeds fuel from the in tank fuel line, to the carb, not sure what its called...secondary impulse line?

It's just a fuel line, the impulse line runs from the base of the engine to the carb to operate like a pump.
