Dear All,
I got a lawn mower with a B&S Sprint 375 engine. The engine runs very well and it always starts first go but it blows a noticeable amount of smoke.
This is what I�ve done so far in order to isolate the potential cause of this problem:
- Replaced old fuel with fresh fuel: no difference
- Replaced fuel diaphragm on carby: engine runs better, but no difference on smoke
- Checked oil level: just below max. Oil looks old and black, but there is no water in it
- Run engine with oil breather tube disconnected from carby: no changes on smoke.
At this point would you consider to replace the rings or there is anything else I can do before taking the engine apart?
Thanks in advance for your comments.
Max
