Kipor kaput

[rosssavage]

Don’t tell me to bin it.

Don’t tell me to buy a Honda.

Kipor IG2000 sprang a nasty fuel leak a couple years ago (emptied the whole tank on the floor in about 30 secs, whilst running!! Luckily no fire...) so it was relegated to the garage.

This week I bought a new fuel pump for it (inter web forums suggested this to be the culprit) and now the damn thing won’t run..

I have:
Drained old fuel, refilled with fresh bought yesterday from a petrol station.
Replaced the spark plug with a brand new one. Checked spark - nice, fat white spark.
Removed the carb, removed main jet and emulsion tube, cleaned all with solvent and blown through with compressed air. I’ve done this twice after it wouldn’t start after the first cleaning.
Checked for fuel leaks (none).

It fires - once, then dies. It did fire and run for three cycles then died. Now I’m back to firing once every five pulls (roughly...).

Choke on, choke off, throttle open throttle closed, and all permutations repeatedly- doesn’t seem to make much difference, still the odd single firing then nothing.

For the first time in my life, I went to Halfords and bought some easy start (I was getting desperate!) but that makes no difference. (Except a smelly mess in the air filter housing..)

I have blisters. What am I missing?!

What are you missing? ... That H*nda you don't want to buy! ... :encouragement:

 

[rosssavage]

Just don’t like throwing things away when I can fix them! This one is a head scratcher though....


And I really, really can’t justify the Honda - if I were to replace it, I’d get another Kipor.... it’s 12 years old now, and up until the leak had been faultless....

I got my EU2.0i VAT free for some reason, a few years ago, probably off the back of a lorry. They do​ turn up on E-Bay now and then at reasonable prices and they seem to last forever!

"Honda EU 2.0i" on E-Bay has just brought up loads of reasonably priced second hand ones.

I'd be triple checking that carb, especially the jet, might need more than solvent.
Has the new pump primed itself?
After so many failed start attempts, I'd expect the spark plug to be awash with petrol, requiring cleaning.
If it isn't ...

Contemplating a new carb - £40 from Kipor UK.

Deffo lots of fuel - yesterday I checked the plug, and it was awash. Cleaned it, tried again. Went to the local lawnmower shop and bought a brand new plug this morning, yes, probably needs cleaning again!

Must be carb - the damn thing fires then dies, so I think ignition is good. Blocked jet makes sense - lots of pulls get a bit of fuel through, one fire but then not enough fuel pulling through to sustain it.

New pump is primed - again, cylinder is definitely wet!

Maybe you flooded it, leave the plug out overnight and give it a few pulls with the plug out too (careful though as that is dead dodgy!)

Hmmm, had a very similar thing with a petrol leaf blower, less than a year old, even down to trying Easy Start. Turned out Piston was knackered, in the bin.

I had similar issues with two lawnmowers and a 2 stroke outboard a few years ago. In all cases the carbs were knackered by the alcohol in modern petrol - it rots all the little seals and gaskets etc. Problem solved with new carb or a rebuild kit with all new rubbery bits. when you first took the carb to bits was there any evidenceof black dust or particules?

For £40 new carb could be worth a go.
Go easy with the easy start though it can break the piston rings.

 

[kashurst]

another idea - is the float chamber full of petrol when you disassemble the carb? if not check the pump etc.
also have you tried pouring a teaspoon of petrol into the entrance of the carb and immediately trying to start it? most things will kick off with this for a few seconds worth of running. might help define the cause of the problem

I had similar with my lawnmower, in the end I sprayed carb cleaner in the carb with engine running and within a few minutes ran smoothly again. I also left the carb cleaner in the carb for a while before running engine. Might be worth a try.

I think you need to quantify the bit where you say “within a few minutes”. How many minutes?
When you say that you left the carb in the cleaner for “a while”, how long is that?

 

[Portofino]

If you are gonna take the carb off and semi strip for cleaning on a bench to remove any gum ,try your wife ( or you own in today’s world of PC correction ) Nail varnish remover ,
Squirt / blow it through or soak etc .
Then flush with petrol , then reassemble it all .

 

[rosssavage]

It’s got to the point where for £40 I think I’ll throw a new carb on - if that fails I’m thinking bin it! It did about 12 trouble free years before the leak that started the problems, so if I buy another I’m still quids in over a Honda.

Portofino - yup, but I’ve stripped and cleaned twice, with no discernible difference. Agree I could try different methods, but again, for £40 that same a load if my time.

Scubadoo - I wish I could get it to run long enough to try that!

And Kashurst - lots of fuel in the float bowl, and the design of the carb / air filter housing is such that I can’t put anything directly into the carb - as soon as the air filter housing is removed for access, the seal between carb and inlet manifold is compromised (two long studs hold the whole assembly together in compression)

Thanks all for your time and advice!

Nice one, that did make me laugh, it was about 5 minutes lol.
