Hi Guys,
Got one I am not 100% sure about before I progress.
I acquired Briggs and Stratton 375 Sprint Engine (It�s a slightly older briggs with the starter clutch). A very good engine from my experience.
Model 98902 Type 0363-01 Code 94092003
I�ll do my best to describe the problem.
So far I have:
Cleaned the carb and replaced the diaphragm
Replaced Pull rope
Replaced spark plug
Replaced the oil
Replaced the bottom oil seal
Upon getting the engine back together it started pretty easily and sounded quite good. Once the engine was put under load it started to pop ever so slightly from the exhaust and once the engine was quite warm (10 mins or so of heaving mowing) it lost some power. Not a lot but noticeable.
When restarting the engine is started and chugged and after a few seconds it eventually got back up to the required speed.
As a result of the initial test I proceeded to check the tappet clearances
Exhaust - .20mm
Inlet � couldn�t fit the .04mm gauge.
At this stage I am thinking about laping the exhaust valve only and ever so slightly grinding and lapping the inlet valve.
Wouldn�t mind some pointers. I�ll put some photos up tomorrow!
