**dear140** · 09-04-2010, 05:16 PM

lol ill clean carb. i do have spark. checked the petcock isnt clogged.idk which way float goes in but ill look at a blown up diagram n check.

**dainpstewart** · 09-04-2010, 05:59 PM

have you adjusted the carb at all yet? i dont know about yamahas because i have never had, or worked on one, but turn the needles in all the way, making sure that you dont torque them in, and bring them out 1 to 2 turns, and work it from there...also, make sure its not in gear and give it a bit of throttle while pulling it. dont know if this will help, but yeah, thats all i got.

a motor needs fuel, spark,timing, and compression .eliminate them one at time till you find the culprit

**dear140** · 09-07-2010, 01:19 PM

got spark, fuel, and compression. idk about timing. is the float supposed to be able to go up n down freely?

**atctim** · 09-07-2010, 01:40 PM

yes - the float should operate up and down freely - this is what fills the carb bowl with gas - it is like the same concept at in the back of your toilet under the top lid.

put a little gas down the spark plug hole and see if it will fire.

fuel in the tank does not mean fuel in the combustion chamber

**dear140** · 09-07-2010, 02:43 PM

how can i check to see if its in combustion chamber? i tried fuel in spark plug hole. no fire. got a new NGK plug got no spark for some reason no spark. old spark has spark new one doesnt... cdi someone said? thanks for your activity everyone.

**harryredtrike** · 09-07-2010, 02:51 PM

what the numbers on the new plug,did you gap it?should be ngk d7ea right

**dear140** · 09-07-2010, 08:07 PM

Yup its a D7EA. pre gapped.NGK of course. just cleaned carb it is and was clean. but just gumouted it to make sure. should my inlet valve be able to come in n out super easily? like if i tip the body upside down the inlet valve falls out.

**dear140** · 09-07-2010, 08:09 PM

oh and my plug isnt wet. when its in n i pull it over.

**84atc200** · 09-07-2010, 09:40 PM

Then you're not getting fuel into the cylinder.You may have to adjust your floats.

**dear140** · 09-08-2010, 05:29 PM

i adjusted my float drastically down and up. seems to make no difference.

**dear140** · 09-15-2010, 04:56 PM

alright guys my carb is clean, fuels getting in there. i have spark. and it pulls over with the same amount of pressure as my other machine so i dont think its a compression issue. i dont know what to do next. tried gas in the cylinder, starting fluid in cylinder and on air filter. i just dont know which way to turn on this.

**krazykane** · 09-15-2010, 05:27 PM

try to pop start by pulling it with another machine

^^^That'll fix everything.^^^
