Why is my carburettor not working on my ttr250?
Spray it through with carb cleaner but, most importantly, ream it with a piece of soft copper wire to make sure any old petrol deposit or debris is cleaned out. A blocked or partially blocked pilot jet is the biggest cause of poor slow running on a TTR250.
How do you clean a ttr250 carburettor choke?
An alternative method of cleaning the filter is to hold the carb upside down, flush it with petrol or carb cleaner and blow out and rubbish with compressed air. Check that the small brass jet that in the choke’s fuel supply line is clear as it is quite small and can easily be blocked by debris. This will cause poor cold starting and idling.
Where is the main jet number on a ttr250?
Main and pilot jet size numbers are located as in the 2nd photo – pilot jet number on the top and main jet on the side of the jet. The main jet can be removed with an 8mm spanner or socket. The emulsifier and main jet rarely suffer from blockages so just clean them with carb cleaner and blow them out with compressed air if available.
