I have a Briggs and Stratton 3.5HP Model 929902 Type 3176-01. I picked it up at a yard sale and have been cleaning it up. The engine manufacture date is 8/24/1982 so she has a few years.
I have it running fairly well but have noticed that it does not start as smoothly as I would like. On a cold start it will fire up, get up to RPM and then die (I suspect as the automatic choke opens up.) On the second pull it will fire up again, get up to full RPM and run very well and restart with no problems.
The carb sits on top of the tank with the jets drawing directly from the tank instead of a bowl making the carb draw the gas up a slightly longer path. I have also noticed that later versions of this carburetor style have a bulb primer.
Is this startup behavior normal or will the carb benefit from a full cleaning? Given its age and condition I will likely need a carb kit with new gaskets and diaphragm so don’t want to tear it down for cleaning if there will be no improvement in startup performance.
Advice will be greatly appreciated.
