I got a Tecumseh hs40-55513e engine and I cannot get it to start. and I replaced the carburetor, and gaskets, and replaced the condenser, and the plug, and adjusted the points to 20 thousandths. and I still cannot get it to start any help will be appreciated thanks Andrew.

You told us what you did mechanically, but not the following. Did you check for spark? Did you check for fuel getting to the cylinder? When you changed the points, did you adjust the timing? If you have spark and fuel my bet is that you did not set the timing, which must be done when changing or adjusting the points. This is not easy to do unless you have the proper tools. This manual may help you out and has the procedure for setting the timing.

yep I got spark bud. fuel is not getting to the cylinder. how do I change that? I didn't change the points but I meant the condenser. no I did not adjust the timing how do I do that?.

Remove the bowl from the carb is it majorly crusty to dried gas? does the float drop when u remove the bowl? I start there before totally taking apart the carb and soaking it. Super easy problem - where the float gets stuck over the winter in the up position, worst- totally crusty deposits from sitting for a year. Post what u find.

it's got a brand new carburetor and carb gaskets on it.

First you need to spray some carb cleaner into the cylinder and see if the engine will fire. If it fires but does not stay running you have a fuel problem, carb or intake. No pop I would be checking the timing. Did you even look at the manual I posted, it has a procedure to check timing, but as I said it is not easy without special tools or past experience.

I will try timing it. cause I sprayed carb and choke cleaner in the throat of the carb and nothing. i will let you guys know what happens. thanks Andrew.

Check the flywheel key to see if it is sheared.

Also check to see if you have compression, then check spark timing.

Hi Andrew,

Try starting fluid down in the carb, not carb and choke cleaner and see what happens.

thanks guys i will try that and let you know thanks andrew

did not help still no go. also i'm noticing the threads on the crankshaft on the flywheel side is starting to get damaged. this time when I screw it in and torque it. i'm only able to get about 60 ft. lbs. then I feel it start to strip. is my engine going to need a whole complete rebuild? I hope I don't have to.

I almost did not respond to this thread but it kept nagging at me. I looked up your torq specs and nothing in there is over 59 ft lbs and as with most small engines inch lbs is the norm. Check your info again to make sure you are not over-torquing your nuts and bolts.

ur right it's 46 ft. lbs my bad .

I am just going to try to buy a new hs40 engine from ebay, and stick it on and when I then get enough money, I will just rebuild the whole entire engine. you think that would be better? were supposed to get about 11 to 17 inches of snow this weekend. let me know guys thanks.
