It was funny the first time (You Tube Master Mechanic). I can take it, but I repeat, "say what you want about You tube, but there is usually someone else out there that has gone through this" So I use You tube and the Forums a lot to help in repairs. No budget to take it to a repair shop every...

My next step I think is going to be pulling the carb off and removing fuel bowl. Give it a good cleaning and see what happens. It will have to wait til next weekend though. At least I know how to get the hot engine to restart with the primer bulb even if it isn't that healthy on the engine. Not...

Spark plug looked ok, just pulled it out of a hot engine, man that sucker was hot. here is a pic. I have a brand new autolite 3924 that says it crosses to a RC12YC i can install if needed. Electrode looks like a new one.

I do not have any choke on this mower. Carburetor has a priming bulb on the intake, next thing in the carb is the automatic throttle control as see in pictures I posted on 8/29.There is no manual choke auto choke or thermostat to control an automatic choke.

ok, just saw Mower Kings post. but I already spent a whopping $4 for the bulb and installed to find out that didn't really fix the underlying issue, but at least I know how to get it started again in hot condition. I couldn't figure how changing a rubber bulb that was not cracked was going to...

Test of primer bulb results: cold start- 3 x push on primer bulb + 4 pulls on the rope = starts right up. Run for 10 minutes, shut off and let 5 minutes pass to simulate time to dump grass catcher. Hot start- 35 pulls on rope and at pulls 12,15 and 21 back fired through carb and popped pretty...

Understood. Thermostat is for choke system engines. I have the primer bulb system. I am going to prime it with it hot and not starting to see if that fixes anything tomorrow. If priming helps, then I will change just the primer bulb. Still a little confused about how this is causing hard to...

Ok, no choke, not sure I understand the concept of no choke system, but I got it. I sure miss the mowers I grew up with. Mounted on the handle was a throttle/choke control with a turtle and rabbit icon. Worked great until all these kill levers and such came along.

Spark plug looks fine by the way, first thing i checked along with the oil level.

Ok I will try to prime it tomorrow on a hot engine to see if it helps it start. This is a 15yr old mower by the way so it won't surprise me if the primer is malfunctioning. There again as I stated above this is why I am trying to fix it for the neighbor instead of a small engine shop at $30 an hr.

Ok, so now I am straight on this is the THROTTLE. Does the throttle butterfly have anything to do with original problem. Pulling on the rope forever to get it to fire up again after dumping grass catcher. It seems to start up pretty well if you let it cool down. So maybe back to this thermostat...

LOL. Yuk, yuk , yuk. still better than paying $30 hr to a shop.

primer bulb?? How does that come into play when engine is hot. 3 prime pumps at cold start and it fires right up. I have never used the primer after engine hot. Are you supposed to?

Ok, my bad. I was thinking this is choke system. this is throttle system, sorry. Ok now what. LOL.

I will try to post a video of it running tomorrow, but the only thing visible when running is the plastic lever on top of the butterfly, that is why I marked it with a line in the direction of the valve. Strangest thing.
