Bike fires up but under load will backfire.. changed plugs wires and jet needle. any ideas


Please tell me the year and model of your bike. I also need to know the type of carb and any specific changes you made to the carb. I also need a clarification of the term "backfire". By this do you mean it's popping through the mufflers or spitting back out the carburetor. Some people use different terminology for different things.

Thanks
Steve

My 1999 Honda shadow backfires on deceleration after steady throttle what could cause this? I have tuned it and cleaned the carb but it still does it.


The most common reason for backfiring is lack of back pressure from changing the exhaust. To compensate for the flat spot you get you put in a jet kit. This leaves the possibility of more unburned gas getting into the exhaust. Honda uses Kei Hin carbs with a fuel shut off diaphragm to help limit this condition (backfiring) by turning off the fuel to the carbs during deceleration. Even stock exhaust can pop or backfire. Typically it is caused by air getting into the exhaust either past the copper o-ring gaskets in the head or leaking muffler connections from the head pipes to the mufflers. Try replacing all the exhaust gaskets and you should minimize this condition.

It is acting like it isnt getting gas. i have already put 2 new fuel pumps on it and filters and cleaned the lines. what could it be?


Injectors need cleaning. You need them professionally cleaned using pulse cleaning. It is sometimes easier to just buy new ones.

Vote for me if this helps thanks.

When I try to start my weedeater gas comes out of the muffler


Sounds like you will need to clean your carburetor.
Sometimes you can get by with priming it a few times, and letting it
run a few times like that and it will flush the gunk out of the jets,
but most of the time you will need to rebuild the carburetor.
If the mower is over a couple years old, then I also recommend that you
buy and install a new carburetor repair kit, because the diaphragm will
get hard and that will cause it to be hard to crank.
When you clean your carburetor and remove the jet screws, count the
number of turns it takes to seat the jets from their original position.
That way when you go to put the jets back in, you know how many turns
they were in/out.
Please rate me, Thanks
Good Luck, I hope this helped

I have a troy built self propelled mower, it ran great last season, now it will not stay running. I checked to see if it was getting fuel and it is. I primed it and it acts like it is going to run and then...


The jets in carbs are really small and clog easily. If you stored your mower with gas in it start by replacing the gas. Remove the air filter and prime the carb. Start the engine and place your fingers over the air intake on the carb. This will cause the engine to stall as it will be starved for air. It will also create a powerful suction on the jets and possibly dislodge a blockage. Prime the engine again and start. If does not continue to run, repeat the steps again. If after 3-4 tries your engine wont run you will have to remove the carb and clean the jets manually. The reason your engine runs for a short time is because it is burning the fuel that you put in there by priming it. After that the fuel comes through the jets in the carb and if these jets are clogged the engine will die.

Backfire Tecumseh Generator


To maybe convert your Flamethrower back to a generator, Make sure the fuel line is a good quality thick rubber material (like OEM )since it passes through the engine,HEAT is a issue, if it has been modified to steel, or it's thin rubber, it will overheat the fuel on its way to the carb and cause backfires after the engine warms up , ( vaporizing gas and pressure bypassing the jets flooding the engine) I use 1/4 inch Goodyear sold at Autozone , one of very few name brand quality parts you can get there. The other possible cause is carbon deposits built up on the leading edge of the valve not allowing the valve to close all the way, just clean the valve, it is caused by too lean or rich carb setting or clogged jets, if it is a newer style carb with a pink main jet then debris in this area will always cause backfire, check and make sure the old tiny O-ring on this jet is not still in the bottom of the shaft, people forget to pull them out all the time or give up trying to pull them out, I use a paper clip and bend the end 1/8 of a inch @ 90 degrees to fish hook it out of there, CLEAN THE SHAFT with carb cleaner and a Q-tip.... A Tecumseh engine will always backfire if the carb or airflow is not perfect and sealed tight !!!!!! it looks simple to rebuild the carb but you must take your time and look close, clean it very well, make sure the jet is SEATED properly and all tiny holes are clean, use guitar string not torch head cleaners as they will enlarge the holes and make your carb run rich.

Engine backfire


try pulling the choke out a little and see if that doesn't help.  If it does that is a sign that you are running too lean and need the jets in the carb increased or just the air mixture screw adjusted.  If the coke test doesn't help, please tell me more about how and when it acts up. Like after the motor is warmed up does the backfiring quit?

Misfire and backfire at low rpm, runs rough at low rpm


You did not say whether or not this was a carburater engine but from the sound of it one of your jets may be sticking, a good cleaning of the jets will most likely fix the problem, the likely cause is a small build up or piece of debris on the jet.
