    TTR 90 Running Rich...tried everything

    I put an 80 main in it and it runs like a champ. Still confused as to why, but I have gotten over it. Thanks for the help.

    I have the stock 95 main in it. That is what is confusing me. If everything is stock, why would I need a smaller main? That seems to be the best overall answer, so I will give it a try.

    Tried it, no luck. Valves seat and maintain compression.

    TTR 90 Running Rich...tried everything

    I got a 2004 TTR 90 from my boss, the price was right, free. He told me it needed a new float needle. I bought a carb rebuild kit and cleaned/rebuilt the carb. It runs great up to about 1/2 to full throttle, then runs rough and cuts out. I ran it until it cut out then hit the kill switch and coasted in. Pulled the plug and it is running rich. I talked to my boss and he said it ran great, then it sat over the winter and it would cut out at 3/4 to full throttle. With this bit of info, I pulled the carb back off and re-cleaned it, this time soaking it overnight in solvent. I don't know if I can get it any cleaner without dissolving away the carb itself. Still running rich. I have done all normal things to include: New plug, adjusted fuel screw, adjusted idle screw, adjusted needle height, checked valve clearances, checked resistances on coil, checked float height, (all within specs), checked exhaust pipe for blockage, fresh ethanol free gas, choke working correctly. After running it without the air filter, I check the boot and it is wet with fuel. When running it on a stand I noticed it has a mist of fuel coming out the front of the carb, which to me indicates timing issues, but I don't know of anyway to adjust the timing. Everything inside the carb is new, except the needle jet, not sure why that doesn't come in the kit, but it was soaked in solvent overnight as well and cleaned. Can easily see daylight through it. With everything else stock, don't know why it is running rich. Please, someone give me the simple answer I'm overlooking. How can a 90 cc 4 stroke be this complicated?
