A very strange situation...

[primerbulb120]

Both the Qualcast and Flymo use a Briggs engine with the tank mounted plastic vacu-jet carb. I not familiar with PVC, please explain. I'm betting your problem is with the diaphragm between the carb and tank. This diaphragm brings the fuel into the carb and if it is old, cracked, or loose it will not work properly.

The engine on this mower is a Tecumseh, not a Briggs. It doesn't have a carb diaphragm.

That is definitely a Tecumseh engine, I can tell by the second picture.

There should be a decal on the recoil starter (part in the second picture) with the engine model number.

Im sorry, no such luck. Other than the green Qualcast Trojan sticker there are no other marks or stickers on the starter housing

Ive been looking online for a while now at images and videos of tecumseh engines and all the ones that I have seen have a PCV connection and 2 pipes coming from the carb which doesn't help me much as my carb has 2 connections for pipes but the actual engine doesn't seem to have anything. 1 pipe from the fuel and thats it?

Spooky lool

Ok after struggling for engine numbers for this mower I thought I might be able to identify the engine number or possible numbers by matching the gasket sets.

As I have had the engine in bits I thought I could visually match the gaskets and hopefully gain some kind of insight.

I was just about to quit when I came across this set:



My best guess is that this is the gasket set for the engine I have.

The gasket to the far right at the bottom next to the O gasket was not present in any of the other kits I saw and I viewed quite a few and it is definitely one from my mower engine the unorthodox shape is quite easily recognised. Its from the inlet manifold connected to the engine side of the carb.

The other gaskets can also be accounted for excluding the largest which I am guessing is the block (bottom end) the only one I have not removed from my engine.

I know that this is a ridiculous way to try to identify an engine code however I don't seem to have many options at this point.

Going by the gasket voodoo the engine code could be either:

HS50, HSSK or LH195

If anyone (or google) knows anything about any of these codes I could cross reference info with the engine I have and possibly rule out codes or positively match codes depending on the info found.

E for effort eh? I guess time will tell if its genius or el'stupido lol

So, what do you need the model number/code for again? (I forgot):laughing:

Im trying to identify if the carb that is on the engine is the correct one. It has two connections a fuel line and a PCV however I cannot find a PCV for it to connect to on the engine and cannot get it started after priming.

The guy I got it off replaced the carb so possibly the wrong one, which wold be ok if i knew what the right one for it was... Hence the engine code lolcry

If you could post some pictures of the whole engine and of the carb, that would help a lot. :smile:

Yup carb and muffler are on the same side so that clears that up it is definitely a Tecumseh which is half the battle won.

Ok on to problem #2...

#2 Carb has two connections for pipes but the lawnmower only has 1? Do i have the wrong carb for the engine?

never mind it is getting late and i'm not thinking right.

Just downloaded this badboy

View attachment tecumsehcarburetormanual.pdf

And couldn't see a carb with 2 connections for fuel and PCV... Strange because the horizontal shaft engines I saw online definitely had PCV and fuel connections.

Its 3am here and my eyes have gone square so I may have missed it. Will have another look tomorrow when my brain is functioning

You don't have 2 holes for the engine you have one for the engine and one for the air cleaner.

So am I right in thinking 1 pipe goes from carb to fuel tank

And the other goes from the carb into the air filter?

Would explain alot!
