Quick question about fuel injectors

My Holley Projection seems to be running way to rich. I checked the injectors with a timing light and you could see lots of droplets of fuel in the mist. Are throttle body injectors supposed to be a fine mist? I seem to remember reading somwhere that they weren't.

Thanks,
jeff

Re: Quick question about fuel injectors

Yes, you're correct... the injector should deliver the fuel in a spray pattern. Go to you auto parts store and see about getting a rebuild kit or a replacement. Often you can just take them apart, clean, burnish and reassemble them and have 'em work fine.

Look at the pintle. If it's got deposits on it, it may not be closing properly. That's a fuel leak. The screen behind the injector may also be clogged from deposits and may be needing a good cleaning. When the pintle opens and the fuel starts to spurt out in dropplets... something'w wrong, it should be a defined spray pattern.

Happy Holidays and Safe Jeepin'
