Check the boot between the carb and the cylinder, it could be an air leak. also check the compression. If the piston rings are damaged then it wont have the compression to pull the fuel through. Could also be a damaged fuel line, or plugged filter.

  • I was given a TS350 Super by a friend. It runs fine, but is has a slow continual fuel leak. If I leave it with the fuel, all the fuel will leak out of the bottom at a slow rate. Any solution or where to start? Any service manual available for this model online?

SOURCE: ts400 runs a while the

Does it run normally until it has warmed up? Check for a spark immediately after it cuts out. This fault can be caused when the coil has deteriorated and heat from the engine causes the coil to fail.

With the TS400, the other major common failure is the main bearings leading to crankcase seal failure which will cause the machine to run lean and cut out. This can easily be check for by taking the pull cord and side covers off and checking for play by trying to move the flywheel/clutch up and down. If there is any up and down movement relative to the casing the bearings have gone.
