car starts then stops

[spyderpact]

Well I got my car to work for a few weeks now, but yesterday was different. When I would push the gas full or med it would just die after id stop or after i press the brake I would start it again and the same problem would happen. any thoughts?

You dont happen to have the temps do you? Sounds to me like its running too lean. And it seems that you might have an air leak. That would explain why it happened all of the sudden for no apparent reason.

Or if it is happening only when you hit the brake, the idle stop may just need to be adjusted.

Reset the high and low speed needles back to factory settings and retune. You'll find that you have to retune your engine often because the mixture really responds to daily changes in conditions. If it's a warmer or colder day, more or less humidity. All types of things. So be prepared to have to change your needle settings on any given day.

i put regular permatex blue thread lock after taking off the motor to clean the chassis.i just checked today to see if they are loose........they were still tight after all the ruts i hit while driving it yesterday

Check your idle screw setting. Could also be your LSN settings. Just as CM said, bring your needle settings to fctory and start retuning. Also, check your idle screw settiing to make sure your throttle opening is ok. 1mm or the thickness of a credit card is what you're looking for when you look down the throat of the carb.

One of the first things I do when an engine starts acting up, is take off the air filter and fuel line, then spray the carb with WD-40, and blow out with compressed air. I usually try to take out the HSN assembly for this procedure and spray all those little parts out too. This has worked a bunch of times.

If this does not work, then I look for air leaks and take a compression test. The great thing about these engines is their simplicity. Pretty easy for the average guy to fix. But they do need a lot of fixin', so that's the downside.
