HI,
I currently running the tm45 with a 40 pilot & 155 main, when at idle it will frequently pop the the carburetor and die immediatly, the only way to overcome this problem is the idle it around 1500-2000 RPMs, Is this caused by a lean pilot ? Or do I need to adjust something ? Thanks, Matt

 

play with your air screw, turn in to richen first. are u using stock air tube between carb and air filter?? if so, richen up your main jet.

 

I am not running the stock tube, I am using 2.25 inch PVC to a K&N air filter, no airbox. I will adjust the air/fuel screw today and see if that help's, Thanks for replying.

 

On the TM you need to either run the direct mout or the stock tube.

Direct mount needs a 150 ish main ,the tube will want a 160ish main.

The pvc pipe will lost power from bottom to top and though the range.

The air screw needs to be about 3/4 to 1 turn out. Are you useing the pump??

 

Thanks thebom, I will remove the pvc piping soon then, Ill put the stock tube on there, my bike seems to be running fairly strong at the moment, though . I adjusted the Air/fuel mix screw and that was the problem Thanks guy's, Matt

 

Hey fellas....

I have the same problem with my TM45 and idle... however, mine is more than likely from sitting so long (in storage).

In a pumper carb...
Where's the first place to start to clean out old fuel and passage ways. Before I take the carb off, and get out the airgun I want to make sure I'm not doing more than I need. It'll run if I pump the gas, so I know it's a lack of fuel....

Clogged jet... or???

I'm leaving for the dez Monday am... any help is appreciated! And Happy Holidays!

John

 

Never mind... got it.

The pilot jet was a bit clogged. She runs fine now.... nice and snappy.
