QuestionHi Ben -
I have searched through some Q & A's regarding this issue I am having with my Honda Small Gas Engine. But I have not found the correct answer yet.
My engine: Honda GX200 6.5 HP, GCACT-1206169 QX2 Family: 2HNXS 1961AK
Carburetor: 64YWSD19 BE KEI-HIN
This engine is mounted on a log splitter.
------------------------------------------------------------------
The engine starts & runs with one pull of the starter rope and then shuts off after about 30 seconds. It does not matter where the throttle is set (low to high). The engine will also stall almost immediately when the splitter ram is operated.
1. I have flushed the fuel tank with new gas
2. I tried running the engine with the fuel cap off to eliminate the cap as a potential cause.
3. I checked the in-tank fuel filter - it is clean.
4. I checked the gas delivery to the carburetor - it flows well and strong.
5. I checked the crankcase breather tube - it is clean.
6. I checked the air filters (dual stage) - they are fine.
7. I removed the sediment bowl and cleaned out some dirty fuel.
8. I removed dirty fuel out of the float bowl & shut off valve.
9. I removed & disassembled the carburetor, removed the main jet, sprayed everything with carb cleaner about 3-4 times then blew it out with compressed air.
10. I removed the flywheel cover to check for debris around the governor linkage (only to find out that the governor shaft is behind the flywheel & the governor is in the crankcase).
11. I checked all carb & gov linkages & springs - all appear to be ok.
12. I have not touched the idle screw because there isn't one on this carb!
----------
I am running out of ideas. I'm about to purchase a new carburetor, but I don't think I really need to go through that extreme. The problem may not even be with the carburetor. The engine was running great about 3 months ago. I always use a gas preserver (Sta-Bil) in all of my outdoor power equipment.
I would truly appreciate any assistance you can provide at this point... as I am STUMPED!
Best regards,
Jason

You are way off looking for a carburetor problem.When I was first learning this trade I had a similar problem. I did just about everything you did I even replaced the carb. This engine was going into the trash and I was giving up. But stubborn me kept going and found the problem.
it was a very simple problem had I walked away for a day. The engine has a oil sensor on it.This prevents the engine from overheating by sensing low oil. The sensor is probably bad if you can remove the wires off the sensor and touch the engine metal with the 1 wire it should start. You also have a oil float switch inside the engine if the engine gets tilted where it can not pump oil such as a bad slope it will shut off but I think it is the oil sensor for low oil. Let me know if this works.
