I have an '04 Nissan 120A2 that's having WOT issues. Starts, idles and runs perfect at trolling and low speeds (i.e. 9-15/20ish RPM). Issue is, when throw the control to WOT, seems to be not firing on all 4 cylinders as the motor shakes like its out of timing and possibly one cylinder is getting dragged along. Fuel issue? High speed jet clogged in one carb? Clogged fuel line?
I did go through all plugs and found bottom cylinder plug to be heavily oiled up, cleaned and re-gapped all four and that didn't cure the issue.
I had this issue start back around Thanksgiving, I would open up the motor, give that off time shake/dragging cylinder feel then it would pop out of it and be fine at WOT. Now it won't pop out of it and just shakes like describing.
Going to run a fuel system cleaner and gumout the carbs to start.
Any advice welcome.
Thank you
