3.5 HP Lawn Mower low RPMs?

Well I just got a lawn mower with 3.5 HP Tecumseh engine for $5 at a garage sale, it needed the carb cleaned as it had been sitting for a while and would not run. I have managed to clean the carb and get the engine running, but now it seems as if the RPMs are low. It seemed to cut grass ok but does not seem to rev up like other mowers I have. Any help would be appreciated.

Take a good look at the throttle shaft and where the
link from the governor lever attaches. If you removed
the carb, you could have put the link back in the
WRONG HOLE. Look for the hole in the upper righthand
corner with the throttle CLOSED and it should be
slightly oval=shaped/elongated where the link has
been riding before you got this mower. Doe this mower
have a speed control, either manual know on the bracket
above the carb, or a remote throttle control cable ??

I realize this is an after thought but to avoid linkage problems...be certain to make yourself a "detailed" drawing of the linkage (from several views) before disassembling. They have saved my neck many times. Also, a digital photo is nice.

Hello: Jack

Thanks very much for your suggestion to always make a hand drawn pictorial of the parts prior to disassembly. Doing so is a huge benefit to the first time taking anything mechanical apart.

I also suggest this be done in all my forums and would like to see others doing so as well in any forum dealing with mechanical repairs.
