Compression on # 2 cyl., which the exhaust valve was replaced, 165 lb.s, compression on #1 cyl. 120 lb. s. Thats a 27 to 30 percent difference. Will recheck valve lash on # 2 cyl......it's a little high, wouldn't U think?

Did help, thanks. Between .010 & .012 inches.

Need air gap on the ignition coil for the above blower.

Mean while, back at the ranch............ finally received the exhaust valve...first one lost in transit. Correction on the original post, the original valve head is warped, not bent. When in the seat there is approx. a 1/16 "opening" between the valve and the seat on one side, and if the valve...

Never thought about that......Came into this world in March...37.....1937. Prefer to be addressed as ....Mature

Plum forgot bout that one.

There are 3 conditions which must be in place for any internal combustion engine to run........IE: fuel, spark, time...if those are "in" place any engine should run.

Appreciate the info. I thought 120 # psi was way to high,checked several times, always the same.When I first got the mower it was running, not very well. Checked compression, either 60 or 80 on #1 cylinder and 40 psi on number 2. Disassembled engine. Forgot, set valve lash initially before...

"You simply don't understand governed engines. They are not the same as automotive vehicles where the operator is the governor." You might have a point,but, this I do know, with a throttle to card. control,chances are the engine is not not going to "blow" weather the engine is great or small...

Now, my real problem with this engine, more particularly with Briggs is....Why is the throttle connected to the governor control ??? Thats undoubtedly the biggest "mistake" I've ever seen on a small engine regardless of who makes it. Or, am I that far behind the "curve"? U see, everything I've...

Appreciate the input. Cylinder leak down tester. Problem; neither O'REILLEY'S or Autozone has a loaner, and @ $140+ not going to buy one. Harbor Freight has one for 80 bucks + tax, but gonna pass. Will take the head off and start checking. Engine still on mower.

"Inherited" this engine which was attached to a 50" Troy-Bilt Big Red....Circa 2006. Was running when I got, not very well. Pulled the engine and broke it down. Replaced the complete gov. system. All other parts looked good. Regasket and put it back together, and back on the tractor. Now, the...

No offense taken. Bought most parts from; https://www.briggsstrattonstore.com/ which, come to find out, is not affiliated or part of Briggs & Straton. You're probably right about China made. Will check. This is my first experience with a "small" engine where the throttle is connected to the...

Well, removed the flywheel crankshaft seal without removing the crankshaft. With a cold chisel and hammer without any damage. One of the rod cap bolt is damaged to the point that its going to take a special socket, which I don't have, to remove. Am waiting on gov. parts, shaft, seal, bushings...

"Just note crankshaft seals were replaceable without removing the crankshaft." With a hammer and a cold chizel?

Right now have the engine disassembled to the point that I'M trying to pull the crankshaft but one rod cap bolt is frozen and I have "rounded" the head very "nicely". So, I'm headed to Lowes for some special sockets.Am tearing it down initially to replace the governor shaft, bushings...

Have the service manual which shows how to set the governor. Also, have watched many YTUBE. Problem is none shows/tells where the throttle is to be set or even hooked up.

Have a Troy Built 2007 Red Horse 50in. lawnmower with a 23 hp BR & S. engine. Kinda/sorta "inherited" it. Problem; Wants to start and run wide open. Have moved the linkage every way known to man & beast, still wants to run wide open. Need a linkage routing diagram.
