OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Briggs & Stratton Engines Briggs 35 Classic over revving

Hi. I have had a look at a couple of other threads on this problem and have noticed what seems to be a subtle difference in the govenor link. Some of them seem to have a different length from the looped spring attacment back to the governor vane. In my mind I would think this would have an effect on engine speed? By fiddling without distoring the spring in any way because they are new, I could only get the idle to 2900rpm.

Any suggestions?

This mower was a see if you can sort it by a mate but if no go no loss type of arrangement. It had a snapped intake manifold, no govenor or idle spring, govenor link or muffler. The fuel tank was zip tied into position and any carby linkages were operated by a piece of tie wire. It actually deserved a picture but I missed out.

Anyway it does run but very high rpm. I cleaned the carb and tank, cleaned the air filter, cleaned under the top cover and govenor vane.



Would this hole lower the idle?


This end of the link seems shorter than some of the links in other pictures


The idle spring which I removed for the pictures


I had the idle spring between the link loop and this tab


I have realised from the pictures I need to turn the fitted spring around. At this point I doubt that it would rectify the engine speed issue though.
