hello,i think I may have a injector that's not working.can anyone please tell me the best way to check or to test them without havin to disassemble the the carbs?
the engine runs good but it souds a little weak .and while runnin on lower lower speed I can hear a shurging as if a cylinder is intermitting firing.ive done spark test by pluuin each plug wire and it sounds like its getting good spark ,"can hear it jump at least 3/8 gap"but its hard to tell witch cylinder it is with it just idling.any advice would great. thanks

You want to test the injectors without disassembling the carbs? Do you have carburetors or injectors?

If you have injectors I can think of half a dozen places to send the injectors for cleaning. Not much you can do yourself to get them back in shape.

In order ta "check " anything with tha fuel injection ya gotta have some knowledge of what your lookin' at before ya start. That's how bunches a folks get ita trouble ta start with. FIRST thing if your a novice, is an OEM manual for it. Example ie: its an efi but disassemble tha carbs!!!

There are a coupla ways ta check tha injectors for firin' and pattern but ya gotta know how ta take it apart and what your lookin' at.......Then ya gotta put it all back together.
