My fresh 2056 is really running poor during break in, low power, slight miss maybe. One of the issues I've noticed is when using a laser temp gauge (pointed at the exhaust manifold, directly off the head) I've found #4 is running around 230 Degrees while all other cylinders are in the 330-360 range. I suppose it's more of a EGT temperature as I'm measuring the header, not the head, but regardless number 4 is out of whack and probably where some of my trouble is.
Pulling the #4 plug and it is noticibly wet, sort of oily too. I've got good spark there, swapped plugs too, checked wires. Any ideas what to look for next? |

Last summer Cap'n K. posted a refinement to the "carb cleaner spray to find vac leak" procedure: check small areas at a time, get the straw very close, spray a little, and wait a few seconds before moving on. For years, I'd just fogged a portion of the engine hunting a leak. That sorta works, but this is much better.
