Lawnboy 10671 with a tecumseh LV195EA engine quits often when cold.

Lol no. It's just that I started off on the lawn boy forum and wasn't getting any replies and noticed there was a forum for tecumseh engines and thought maybe I'd get more replies there. Then I got a reply on the lawn boy forums saying that that forum was for old 2 cycle engines only so since then I've been trying to keep both threads updated.

If there's a competition among responders then Rivets should win -- hands down -- he's a professional and I'm a hobbyist. :laughing:
You should read his post in the other forum carefully. He's given some detailed info about cleaning the carb.
I still think the most likely cause is some kind of clogging in the fuel system. Is there a fuel filter... and if so, have you eliminated that as a cause?
I don't have any real data to back this up but I'd bet that the symptoms you describe are overwhelmingly caused by fuel system clogging -- and things like low compression and a leaky manifold gasket would be way down the list. If you had 1000 of these engines with these symptoms, I'd bet that over 900 have fuel system clogging of some sort.
The degree of clogging could be sensitive to heat so it could vary as the engine gets hot.
Again, good luck.

Tomorrow I'm gonna go buy a compression tester along with a tube of gasket maker.
Initially my problem looked like a fuel issue like some have mentioned here but after giving it more thought I think if fuel flow was an issue then it would always be one. Not just for the first 3 or 4 pulls. Fuel flow seems to be just fine after that as the engine does not quit unless it's being bogged down by a heavier load such as in longer grass areas which I think can also be caused by poor compression.
So tomorrow if I get insufficient pr駸ure readings I will start by changing valve cover gasket and fuel intake gasket. Once that's out of the way and If I still have poor psi readings then this will tell me that it's either the valves, piston rings or both.
Now if psi readings are initially good then the other thing I could try is testing the coil with a spark tester to see if it's giving me good sparks on a regular basis....but honestly...I don't think the coil is bad. These solid state coils either work or they don't.
My wife keeps telling me to just buy a new mower and be done with it but at this point this little problem of mine has become some sort of challenge and I won't be happy till I've solved it

Thanks. I've done everything I could think of in regards to fuel flow other than just replacing the carb. Taken the carb apart several times and cleaned and recleaned everything. Made sure float was at the correct height. Made sure all holes were clean.
Wait there is one last thing I could try. Fuel filter is in the tank and I don't have access to it so I could try to swap the tank with another container and connect the hose on that and see if that fixes it. Another Avenue I just thought about is the impulse breather that connects to the upper portion of the carb. I read that this hose sends air into the carb at impulse and keeps the bowl full of fuel. I've tested it by unplugging it from the carb and you can definitely feel the impulses air coming out but maybe there's not enough pressure....or the hose is worn out and the carb isn't getting a strong enough impulsion but then again the same question comes back to haunt me and that's why does the engine not stall after 3 or 4 runs...
