How are you checking your RPMS ???

If you had a fine running engine and changed the carb then you are chasing your tail to get it running faster.......

You mentioned it was a Briggs and Stratton............. I don't know what HP engine you have or the model number of it, but there is a very simple way to do a RPM adjustment on all of the 3 to 7 HP engines...

I would use a tachometer to do the adjustment right though......

Let us know what you have...

A model number will help a lot .........

hi,im just guessing the rpm. it increases off tick over then sounds like its choking up, then throttlel back and it ticks ever fine the model number is 1490702 i changed carb because when i took it apart to clean i noticed main jet was stuck and a bit mashed up...and i think its a 13.5 hp..........thanks

any thoughts anyone....i,m stumped!!!

does this mean every one is stumpt too

Everybody is waiting on the actual model number of the engine, as an actual rpm reading from a tach. RPM is not something that you guess on.

i will have to rephrase because of some dick...i ment it revs slightly and the number on previuse post is model number as stamped on rocker cover
