Engine won't start

[Peters Van]

before adjusting the carby make sure your valves are adjusted correctly ans also ensure that the timing is correct.

single carb adjustment method.
1. engine at operating temp then stop motor
2. turn mixture screw in until stop (gently) then back out 1.5 turns
3. start motor then idle screw until desired idle speed. till it sounds right.
4. mixture screw in till idle slows then out half a turn
5. readjust idle.

works for me every time.

Thanks Peters Van, I'll give that a whirl when it's time to go.

I'll double check the valves, I did them before putting the engine back in, but I may as well just in case.

The latest new development (this is becoming a thing) is there appears to be fuel getting into the case itself. This is generally caused by a faulty fuel pump diaphragm, no? (I have new fuel pump on the way). I checked the pump over when I was doing everything else on the engine and it seemed fine to me. On less common occasions this could be the carby at fault too?

Either way I won't be doing much until the new pump arrives, likely next week, but I'll drop the oil today so I don't ruin the engine, and I need to do the trans oil aswell, so I'll probably give that a crack too.

yeah when ive seen fuel in the oil its been the fuel pump diaphragm as you described.

So it turns out the fuel pump is fine, which is what I initially thought as I couldn't find any form of rip, tear or hole in the diaphragm, instead I'm an ass for missing a gasket, so the fuel pressure was just too high and must have been dumping it back into the case. Either way, no fuely oil now. But I still have an exorbitantly expensive fuel pump on the way, so I guess I have a spare one.

Valves were all good still, which checking was less fun with the engine actually in the car

Still flooding a bit, and the float level seems off, with the float itself in surprisingly good condition. I double checked the float needle which after testing a few different ways seemed a tiny bit sticky, cleaned it out a put everything back together. Didn't get a chance to try it as it was getting a bit late, but I'll give it a run tomorrow and see how it is.

If it's still a bit floody, any suggestions? There's only so many things it could be. It's a 32 PHN-1.

Pretty sure I've now solved the flooding problem. I may or may not have accidentally had the choke wound up too much when I rebuilt it as I was testing the spring and potentially forgot to set it back...

So it seems to all be running pretty well (I did like you said for the carb adjustment Peters Van, thanks matey!) for now, but going by this thread so far, I've probably forgot or left something in the wrong spot so we'll see how she runs tomorrow!

Once again thank you everyone for your help!
