Hi, Rdp412 and the usual suspects are:
1. Fuel cap or fuel tank is not venting properly.
2. Fuel filter clogged.
3. Fuel line pinched or kinked.
4. Vacuum line from the petcock to intake manifold cracked.
5. Float needle and seat sticking.
6. Float level too low.
7. Carburetor bowl vent line clogged/blocked/pinched.
8. Idle adjusting screw set too low.
9. Air/fuel mixture screw set too lean.
10. Idle port, transfer ports, slow air jet clogged.
11. Slow fuel jet clogged.
12. Faulty fuel pump.

SOURCE: 2008 TTR 50 yamaha will only start when starting

Sounds like your carby needs some attention mr foleymon. Your engine stalls as soon as the starting fluid is used up in the combustion chamber.! 1. Make sure theres fuel in the tank and it's getting to the combustion chamber(never overlook the obvious).In your case there seems to be a blockage in the pilot jet and/or associated air ways.Pull the jets and blow out with compressed air backwards,IE , from the inside of the jet to the outside....Hope this gets you outta trouble.

Clean or change air filter. Clean, gap or change spark plug. Empty gas tank add fresh gas with Stabil. When spark plug is removed pull rope several times to blow out cylinder. Spray starter fluid in spark plug hole before replacing spark plug. Clean outside of carb so choke works freely. Spray starter fluid into carb breather hole with air filter removed and try to start. if running replace air filter and cover. If no start disassemble carb and clean. If no start replace carb.

Cub Cadet has gas, has spark, has air -still won't start/run


Are you pulling the plug to check for wetness after cranking it a few times, WITHOUT using the starting fluid? Also, I would recommend using carb cleaner in place of the starting fluid. Starting fluid runs the engine VERY hot for a brief time and can possibly damage rings, valves, and aluminum parts.

Model 120502-0255-E1 won't start.


are you sure you have spark? spray a little starting fluid in the carb and see if it runs on that until it burns off. if it doesn't run then it is a different issue other than carb. also, have you checked that the fuel flow is sufficient enough? if you pass all these then replace the carb. should be about 50 bucks and it will save you time and hassle. those carbs aren't really rebuild friendly

Gap the plug at .030 What is most likely the main problem is whatever gas sat in the carb. Even with fresh gas there will be some old gas still in the float bowl. You may be able to drain the bowl and be OK but I have a feeling that the carb will need to come off and be disassembled and cleaned properly. You can try spraying carb cleaner (I dislike starting fluid as it is too volatile and carb cleaner does just as well in this instance) into the carb/intake. Remove the air filter, open the choke, and spray the carb cleaner in through that way if possible. You can actually keep an engine running by spraying with short bursts. Even by just spraying once you should be able to get the engine to start. If it does start but then will not stay running without spraying more into the engine then it is a carb problem.

2001 ttr 225 bike sat all last year. Would start this spring but not idle. Now it won't start. I know the carb had old gas. Where can I find a manual so I can take it apart and know what parts to...


Start by removing and cleaning the carb, it may not need any parts.
also change the oil, fit new air filter, new spark plug, and check the valve clearances

It won't stay running


You need to either clean the carb really good (take it apart) or rebuild it or both. Sounds like your needle is gummed up and not letting fuel through.

Yamaha TTR 125 L won't idle


this is very tipical. when bikes are stored the fuel varishes up the jets & needles. soak the carb. moving it back and forth in the soak solution. then blow every jet and orfice with a controlled air source. note: any speck of rust or dirt can plug these jets. pay attention to detail and do every thing twice. then install the carb and adjust it to your riding style. later Spike
