    Well OK, it takes compression, fuel and timed ignition for these to run....? OK now we need to figure out what is causing your problem. So we know that its a single carb on this model, so if the front cylinder is running (or getting fuel) then we know that the carb is likely working ! Timed igniton, we have spark in the front cylinder, so likely the pick up coil is doing its job What is the compresion on the rear cylinder, do you have a number ?

Why Is My Harley Davidson EVO Backfiring on the Rear Cylinder?

Harley-Davidson EVO may be backfiring on the rear cylinder because it has a wasted spark system. If fuel and electrical is all good/correct it is often the case in these symptoms that motor cycle spark plugs that although looking good and firing outside of the engine are breaking down and will not fire under compression pressures on a power stroke but will fire unburned fuel on the unpressurized exhaust stroke when the plug again fires in a wasted spark ignition system and when so firing the result is a backfire, usually quite loud.

Has compression and fire but dont start

Remove sparkplugs and squirt some fuel in cylinders. Replace sparkplugs and start motor. If it fires up you have a fuel problem and a good carb cleaning should clear the problem.

I own a subaru outback limited sedan 2002 with the ej251. I replaced the engine and the car ran first. Now 1&3 cylendars are not firing at all. I've replaced the cam angle sensor, engine...

My first thought would have been a failed coil. Most 4 cylinder coils fire odd cylinders together, one positive and one negative voltage.
The crank sensor could be faulty too, but I would rule out the coil first.

Yard Machines 13.5 HP riding mower wont start. It turns over fast, has good spark, good gas, good filter, clean carb, just wont fire. It ran fine yesterday and i parked it last night and tried to fire it...

Hi, check that the choke is operating and make sure the plug is wet after cranking. If so replace the sparkplug as it may be breaking down under compression. Also make sure it has compression ad it may have a stuck valve. regards Phil

2002 20hp. 48" cut M# U609H . twin cyl. B&S. Turns over but no start ! Only one cyl. firing! Ran great aweek ago! Plug gunked up on one cyl., but other plug good tan color

Should actually run on one cylinder,but noticeably rough and lack power.
anyway Remove plug from fouled cylinder clean it or replace it next put plug in spark plug boot and ground it near the cylinder against metal ,get on mower and attempt to start as normal and watch the plug for spark? yes ? put plug back in and torque to 18 ft.lbs and gap at .030. if no spark you may have a bad ignition coil for that cylinder or a blown cylinder piston connecting rod or piston ring issue.Find a compression gauge and insert it in that cylinder and turn engine over as if you were trying to start it and watch the gauge, and to determine what reading you should have check the known good cylinder first,if you dont have a gauge put your finger over the sparkplug hole on the supposed bad or fouling cylinder and have someone crank the engine over,you should feel air coming out on compression stroke pushing against your finger and with a small flashlight look into the sparkplug hole to see if the piston is moving back and forth in that cylinder
try to use common sense with this procedure so no one gets hurt !!!

Fireing order 04 midnite star got plug wires mixed

Generally the leads are a tight stretch and having slack if around the wrong way. Take the sparkplugs out and connect each to your best choice of leads. Place these so they are resting metal to metal on the cylinder heads. Place your finger tip tightly over front cylinder sparkplug hole and rotate engine with ignition on. When compression is felt (your finger will "pop" off hole) and the sparkplug that sparks will be the front cylinder coil and lead. Repeat procedure with rear cylinder to confirm.....mark F and R on lead caps when your done!

I have a 1990 fxr with a single fire ignition, cam and s&s carb. I am not getting the rear cylinder to fire. I just cahnged the coil but no change. I have compression out the exhaust pipe for the rear...

With a single fire ignition, you cannot swap the wires. A dual fire ignition, yes, but not a single fire. You need two things to get the cylinders to fire, spark and compression. Take the plugs out of both cylinders. Run a compression test on the rear cylinder. You need at least 100 PSI to get the cylinder to fire like it should.

Next, put your plugs in the wires, (they should already be in the wiresand grounded) and spin the engine over. Watch for the plugs to spark,especially the rear plug. If you have spark and compression it should run on the rear cylinder. If it still doesn't run, either something is way wrong with the ignition or a very bad air leak on the intake.

If you don't have spark at the rear plug, you need to check the coil. A single fire coil is different from a dual fire coil. The primary wiring is different as well. If you've got the primary wired incorrectly, you won't get spark at the rear plug. Go to the website of the manufacturer of your ignition system. Most of them have downloadable installation instructions. Check your primary wiring.
