Got a miss

<< < (2/3) > >>

justfreaky:
Does the backfire or miss seem to cause any proformance loss?
I know on my kart, that after adding the header, I now have a popping sound when letting off the throttle. I will look into jetting, but will wait 'til I get the velocity stack and filter added on. I am certain that the popping is due to excess fuel in the header.
I'm just kind of thinking out loud. I am sure the problem is not likely that serious.

Does the car backfire when your on the gas or off? If off these cars backfire because of the exhaust systems. If on the gas I would guess that the carbs are just a little off. We need a lot more info though.

unplug rev limiter see if it goes away. Check to see if gasket fell  off that goes between aircleaner and carb.                Gil

free2race:
After a complete check of everything. I have decided to throw in the towel on this one. After checking and rechecking the valve lash, gaskets, ground stud, jets and (3) carbs. This thing is junkpile material. The only thing I have not done is disconnect the rev limiter. It seems when you give it gas at about 3,000 rpm it sounds like it's choking on too much fuel and it won't "lean out" and run steady. I have no clue. Thanks for the help. Maybe someone at Monroe can do something with this possible mailbox holder, I know I can't.

justfreaky:
Are you sure your jets aren't too large? Did you try to readjust your air/fuel settings?
How many races do you have on this engine? Maybe it is due for a refesher?
Sorry that I am not of more help.  :-[  It's hard to get a grip on the situation when I can not be there first hand. Don't know that I would be much help anyway.
Let us know what the outcome is.
