Could be running VERY rich causing ignition of the exhaust gases once the second cylinder is on its exhaust cycle. This would cause both flames out of the exhaust as well as the crappy performance. Pull the plugs and see if they're dark.

Clean the plugs
If the plugs look darkened you can use the A\F mixture screw on the carbs to lean out the mixture.

To tune like this.
Find both A\F mixture screws on both carburetors.
Find out which way to spin them to lean the mixture out (for me it was to tighten them).
Using 1\8th turn adjustments do one carb at a time until it runs better\stops backfiring.
Now that it's running decently go for a spin WITH NEW PLUGS, after a good little jaunt let the engine cool and pull the plugs, if they look white you need more fuel, if they look sooty you could need to lean out the mixture 'slightly'.

SOURCE: how do i replace the regulator & stator on a 92

There's nothing to replacing the regulator. It simply bolts to the frame. The wires from the regulator to the stator plug into the plug on the lower left front of the engine case. The larger longer wires runs back along the frame and up to the positive post of the battery.

There's a bit more to replacing the stator. To replace the stator, disconnect the battery and drain the primary case. Remove the outer primary cover. You'll have to take the engine compensator sprocket nut off and remove the mainshaft nut that holds the clutch assembly on. To get the clutch assembly off, remove the snap ring in the center of the clutch assembly and remove the clutch adjuster. The mainshaft nut is inside the hole in the center of the clutch assembly. The nut has LEFT HANDED THREADS. Take the nut off the primary chain adjuster and take the engine sprocket, primary chain with adjuster, and the clutch assembly off all together. The rotor is on the engine sprocket shaft. It can be difficult to get off because of the magnets inside of it. The rotor has two holes in it. I use two long bolts and put them just into the holes deep enough to hold the rotor by squeezing the ends together. Pull the rotor off. The stator is held on by four small Torx bolts and it has a wire support that is held on by two small sheet metal screws. When you install the new stator, make sure you use thread locker on the threads and torque the bolts to 40 inch pounds of torque. The sprocket shaft nut torques to 150-165 foot pounds of torque. The clutch mainshaft nut (LEFT HANDED THREADS) torques to 60-80 foot pounds. You'll probably need a locking bar or some way to prevent the engine from turning while you torque the nuts.

Good Luck

Catalytic converter

The exhaust downpipe is glowing red with heat?
To be honest, that may be fuel-air /and or cylinder head problem. A downpipe gets very hot, yes, but they don't glow red.

A faulty oxygen sensor can cause the catalytic converter to overheat - with disastrous results.

If you're not sure what you're doing don't mess around with things. get somebody who knows what they are doing to look at your car and give you an opinion

What would cause the cat to glow red hot ? Also shows code p0174

What you have is a rich condition! Your cat is glowing because it is working overtime trying to burn unburt gases. Your vehicle is dumping in too much fuel for one reason or another.

Intetia switch for a 1989 pontiac grand prix

Only Ford Products have a Fuel Safety Shut Off Switch

You would be in a very bad accident if one of those

using the vehicle.

Don't get in the habit of misunderstanding all you hear

Frontier with yd25 engine cranks but will not start

are the plugs actually working properly though. you can test by removeing the glowplug rail & test each plug individualy with an ohm meter one probe where rail goes the other where the socket goes on to undo them. I don't know what the spec is but they should all be about the same. the other way is to remove all glow plugs & power them up & see if they glow red after a few seconds they should all take about the same time to glow red. Careful as they get red hot real quick so don't touch them

Ingnitor glows bright yellow or red but oven doesn't light

Hello, welcome to FixYa.

Based on your description,I`d suggest it is the hot surface ignitor for the bake burner that is likely the problem...even though it glows, I'll explain further below.

Here's what you can try to verify if it's indeed the ignitor...if you're mechanically inclined. It'll look like this...


** FIRST unplug the range and turn off the gas to the appliance before attempting any first**

NOTE: Some ranges have an upper broiler the same as the lower (bake) ignitor ( some do some don't ) one could swap the ignitor`s ( very carefully, they are very fragile and don`t like to be handled ) this will allow you to use the bake burner, but it will leave you without the broil function...until you can purchase another.

Here's a helpful link...

This will confirm or dismiss if the ignitor is at fault...99% of the time this is the case. Many people overlook the ignitor, especially if it "glows" since that gives the untrained person the impression it works...that is not the case however. (Ignitor may glow but not have sufficient amperage to open valve, or open the valve slightly, even intermittently...but not hot enough to ignite the gas).

As far as checking them you don't actually need a clamp on (though it is the preferred method) you can also ohm it out to test it as follows...

You should be able to find one at most brick & mortar appliance parts vendors or on-line depot's such as "", "" to name a couple.

You can ask for part number based on the model number for the bake ignitor. The number I use in most applications (it's fairly universal and replaces both long and short ignitors and works in 90% of ranges out there)... is part #12400035.

I would still double check with your model number with the part`s professional`s if you're more comfortable with that.

Hope that help`s. Let me know if I can assist you further or if anything is not clear and good luck.

Thank`s for visiting "fixya" for your repair needs. Please take a moment to rate the assistance you received here and a brief testimony is also appreciated.

I bought a used 2006 Harley Davidson Super Glide Custom with 15,000 miles. I've read forums that said that i need to replace the inner primary drive bearing. Is this true? will Harley pay for this?

Don't believe all that you read. I've seen stuff posted on some of these forums that are way on the rediculous side. If you have concerns, call Harley's Customer Service department and ask if there was a recall on anything on your bike. Have the full frame VIN number handy. I haven't heard anything about the inner primary mainshaft bearing failing or anything about a recall on that part. Usually, if you have a problem in that area, its the seal starts leaking but that's due to normal wear but I've seen bikes with 75,000 miles on them with no leaks, no bearing failures. That's basically "luck of the draw". If there is a recall on anything on the bike, and a search of the VIN number does not show that the service has already been done, Harley will pay for it. If there is no recall, Harley will NOT pay for it.

Good Luck

On the hampton bay remote control fan and light module, i do not have wiring diagram. from my ceiling box, i have a red, a black, a white, and a bare copper wire. I think it is because the light switch has...

Unfortunately, Mark it's really not as simple as it sounds, to connect the wires properly. Because of that third red traveler wire for the 3-way switch. Actually, ceiling fans don't work well, when a 3-way switch is involved, because it was designed only for lighting convenience. When the fan is turned on, the other ceiling lights will start to glow, whether they are ON or not..

You would be much better served if you can locate another line to come off of and wire to that. Of course,y you won't have the convenience of a wall switch to operate it. But, that's what the pull chains on the fan are for.

Hope this helped you and thanks for choosing FixYa.

Hi i have got a uninor no but it is asking 4 puk no and behalf of dat i dont have any alternative no also with me so help me ouut with puk no

PUK code is a SIM specific code assigned by your service provider. No way you can guess & enter it. So, when it asks for the PUK code, don't do anything, get the PUK code from your service provider.

If the wrong PUK is entered ten times in a row, the device will become permanently blocked and unrecoverable, requiring a new SIM card.

You will be asked to verify your credentials before your service provider gives PUK number.

How do I remove the baffles on my 2011 Harley 883L?

Don't, If you want to improve the sound and performance, buy a pair of "slip on" free flowing mufflers. Cycle Shack, Vance & Hines, and many others make the mufllers. You never know when you're going to have to have a pair of "stock" mufflers and they are expensive.

Good luck
