Not getting enough fuel to one cylinder at idle. Did all the normal tricks:
* checked idle jet (clean) * ran idle mixture screw in and out * removed idle jet and mixture screw and blew out * removed idle jet and "plugged the hole" with finger (this should give me a *very* rich mixture, only got down to 15:1 or so) So, it's time to pull the carb. I suspect something is blocking the mixture screw area... Of course I have a race this weekend. Sigh. |

Just for giggles and because it's cheep anyway...for just the cyl that isn't firing, put a new spark plug in it and see what happens. Could be nothing.
I've had a few sets of carbs over the years that when gummed up (one barrel), I'd do the same thing, pull screws, try to blow out passages etc. Every once in a while, it'd need to be done it seemed on one barrel or another. Occasionally, I wouldn't set that barrel as good as I could while fiddling and fouled that plug in short order. Just a thought, can't hurt. |
