Then you have nothing to worry about. On another note IT LIVES. I couldn't wait till tomorrow, had to redo vacuum lines didn't have enough just off carb, so uncapped the intake and connected with a T cranked and she fired up. Only thing I noticed is at an idle it seems to idle than drop about 5 rpm then recover, carb seems to be adjusted correctly, if I richen it rpms drop, when I twist the throttle it revs up nicely no hesitation or popping. Granted I did not let the rpms go over 4.5k just a quick twist and let go, when released motor did not pop or stutter, settled down nice and fast to idle. Going to change oil tomorrow and put plastics back on and take for a little slow cruise thru the neighborhood. I didn't go back and read , but if you have a gravity fed fuel system " if the fuel tank is in the rear up under the seat " then you can get a manual shutoff valve and dump that piece of crap vacuum petcock . many of us have done this . that way you have no need for any vacuum lines. If you don't have a gravity fed system , sorry I should have went back and read before posting . Im glad to hear your getting it going ! |

I actually never said but yea it is gravity fed tank in the rear under seat. And yes I know I could remove it but not having issues with it so going to keep using lol.

How awesome.... If ya haven't yet, you may wanna check the valve lash/gap (as a preventative maintenance .... I just had to adjust the lash on a scooter with only 402 miles on it.... JerryScript said he got a brand new one and the valves were set at almost zero clearance... So, ya may wanna give the valves a look over... Also, It wouldn't hurt to pluck the CVT cover and take a look at the belt... I would actually change it to a Gates Belt when ya get the extra cash.... Anyhow, I'm glad she fired up for ya! Let us know how the test ride goes..... |

So fired it up today, let her warm up, drained the oil and gear oil replaced with fresh, started to make sure was full, and got hit in the face with foamy oils as I opened the fill tube. Long story short had forgot to take the breather tube from valve cover and attach to air cleaner, came attached to the vent tube from cvt. Thought I had a problem drained the oil started to put fresh in and still having problem. Moved the breather tube problem went away. Was going to take for a small cruise but started to sprinkle so tarped the scooter and will try for the test ride in a couple hours if it dries up.

Can't wait to hear the results of the test ride! Last night I tore down the top half of one these TMS engines... Valve lash was set correctly but timing was retarded by 2° .... It's not going to be an issue because I'm installing a BBK and a 4 valve head and can advance the timing to where it's gotta be... But had I not opened this engine, It could have had problems running... Probably Joe Blow talking to his buddy on the assembly line, not paying attention to what he was doing... LOL  Anyhow, I made some pretty good videos of the tear down... I get it published in the next day or so... I also removed the stator to install an 11 pole on there to mate up with the engine it's replacing....Just an FYI, the stator that's on there is an 8 pole with one of the coils being for an AC fed CDI. Other than the 2° retard in the timing, everything else is in order. This is a brand new engine... The piston top was 100% clean. The ports on the valves looked like they had been fired at one point, but the black carbon on them wiped right off with a paper towel... The oil that's in them is filtered, (not recycled) motor oils. I'm going to drain mine before I test fire. |

So went to go for a test drive scooter started right up, let it warm up a little bit, hop on and start to leave, get out the driveway go to give some gas and it just bogs down, anything over 1/4 throttle, thought I had it adjusted right, bring it back home, go to adjust the carb, no change no matter how much I turn it unless I close it then the scooter dies. So pull the carb off put my old one on, start to richen it up rpms go up, 1/4 turns waiting 10 sec then another 1/4 turn, gets to just where the back tire starts to move and doesnt seem to raise rpms when I richen a little more, so turn back 1/8 turn, hop on to go for a ride is better but anything over 1/2 throttle and it bogs, no popping just falls on its face, let off and will pick back up. Hoping my problem isnt going to be like the motor you opened that was 2deg off on timing, dmartin95edit: I did check the valve lash and it was right. |

Part of checking the valves is putting it in time.... You have to bring your piston to TDC to set your valve lash... If the two little holes in cam sprocket do not perfectly align with the top of the head, when you put the flywheel on the T, it's not timed correctly. You need to clarify.. did you actually check your valve lash with your scooter in time? |

Yes I did check with the big hole up and 2 little holes even with the head, don't know why I was thinking could be out of time.

Pulled the old carb apart, the jets were dirty, so pulled the carb completely apart cleaned the jets, a few of the holes I couldn't see thru on both jets so got them all cleaned, and back together I am done for the night fed up with it atm, so going to wait until after work tomorrow to change the carbs back and see if it fixes it.
edit: also e-mailed TMS and seeing if I can't get them to send me a new carb, as this one is definatley not new.

Yea the supposed new carb was dirty, on both jets there were holes plugged up. I was using fresh new gas, when the last motor went one of the first things I did was completely drain the gas tank, and got fresh gas yesterday to fill with.

Ok, I opened up every carb I got from TMS.... They all are gunked up... ...
I just shot off a message to TMS also.... I purchased through Ebay so I have buyer protection... I thought maybe they were re manufactured, but these are just f'n junk.....

Yea I bought directly off their website. Hopefully they don't give me any issues, and will either send me a new carb or send me a refund equal to a carb. Their site advertises as being a NEW complete motor.

So the new carb was dirty ? Yes... I purchase motors from this seller also... Mine are in the same condition that KeiKara describes. Check it out, here's the add on Ebay: Short Case, Long CaseDo you see anything about new motor with used carburetor? The more I sit and think about it, the more ticked I"m getting... I have other carbs I'll be using with these engine so chances are, they wouldv'e been shelved till someone needed a cheap carb... I would have wound up selling someone a bad carb.... Not cool... Not cool at all. |
