SOURCE: rebuilt carbs-starts and idles but wont rev up without choke on

sounds like the main jets are partly pluged, you must remve all brass jets and seats including needle jet and its slide soak in carb cleaner and blow out with compressed air only.. hold up to bright light to verify if all are clean. jim

You did not indicate whether or not you have compression now that you have changed out the gaskets and piston rings. If not, it seems to me that the problem could be a) cracked head or block, b) bad valve(s) or even c) a warped head.

Sorry for the bad news (if I am right).

Stihl ts400 quick cut won't draw fuel. New carb installed same problem exists. I am now getting beyond frustrated. It will start and run for a moment on carb cleaner but when its out of carb cleaner i


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.

Rebuilt a Stihl TS400 concrete saw, and now it wont cut, the engine dies down and has no power but revs up? Ive tried everything!


All these people are missing a basic thing: check the compression. If you did all thus work yourself, you may have reused the head gasket or not installed the new one correctly. It will run with no load, but once force in exerted, the pressure finds the leak and exploits it. There is a reason 2-cycle engines run at 130-160 psi normally.

TS400 has problem drawing fuel on inital start of the day 14plus pulls. fuel must be returning to tank leak back. as it starts usually first pull after inital start.


You could be flooding out the unit, and then starting it after it is flooded. This could be the reason that it is so hard to start. The maximum amount of pulls on choke should be only 3, then move it to the next setting. This should help to make it easier to start. If the unit runs ok after it is started then this is most likely the reason why it is so hard to start. Let me know if this helps. You can click on the add comment button below and let me know. I hope this helps you out.
