Hi,

I have an Ariens ST27LE with the briggs 1350 305 engine.  I am having an odd starting issue.  The engine will start on the first pull (after priming and setting the choke) with no problem when the engine is cold.  If I have to stop for any reason and re-start the engine it takes 3-5 pulls and fiddling with the choke to get it to re-start when the engine is warm.  Spark plug is only a year old.  It has been doing this for the past two years and it is really getting annoying.  We have the same ariens at work and it always starts right back up.  Any ideas?

Try a compression test to see if the valves are out of adjustment.  I have a 305cc B&S Kool bore engine  on my Simplicity.  Starts first pull every time.  Compression was around 120 psi using electric start when I checked it after adjusting the valves a couple years ago.   I personally suspect a fuel issue.  The low speed (idle) circuit might be compromised.  I'd clean the carb first then check/adjust the valves.  When I adjusted mine after maybe 150 hours or so, they were slightly tight however, not enough to effect starting or performance.
