Villiers Mk12 not a Mk25 "help needed"

I dragged my (wife's realy) Mk25 out to give it a run as it's not been started for about 18 months and she wants to paint it up. Problem is it will start but not run. Tried a different plug (one out of a running engine) and it won't even fire with that in Cleaned the carb float chamber still the same. Any ideas guys

I've ordered a new plug but that's going to be next week before I get that, so is there anything I can try now.

Also anyone know where to get the cork washers to seal Ewart taps? I got some for pull/push tap but there the wrong size. Or do I have to pay £6 and get one from George @ Villiers parts.

Thanks in advance for your help,

Stu.

Stu have you still got old petrol in it or are you using fresh?

Have you got a good spark at the points.

As for the cork gasket, just dig deep its better to have the right thing from the start and not have to pay in the long run.

Not checked the points Paul, as for the petrol, yes it is a bit old but it runs all my other engines If I can tell you a bit more about the engine I bought it from Pete AKA Foden and it was running well and he did a lot of work on it (new rings). Problem is I need a few bits and everything he has is expensive so I'll have to go out and sell my body this weekend

Just a bit of info I looked on fleabay for plugs before I went on to Greens plug site and it's worth checking the prices between the 2 sites and the postage is alot cheaper on ebay if your only buying a plug or 2.

My Briggs and Straton is running on last years petrol but it wasent running that great so toped it up with fresh and it runs ok now.

Thats an interesting point about the spark plugs, will keep that in mind as i need one for my Petter a.

It was always a first time starter Stu, I wonder if the flywheel has some rust on it (internally) with standing? When my mate bought it from auction it had no spark, I removed the flywheel and gave it and the coil contacts a good clean (also cleaned the points as well) and it fired straight away. I re- rang it and did the valves as well. You will lose the ignition timing by removing the flywheel, but that is easily sorted. It's a Mark 12 by the way, not a 25.

I knew you'd done a bit of woork on it Pete, and it starts first pull then it's just as it it's running out of petrol and dies away.

Pete I''m sure you said it was a Mk25, now you got me wondering, I'll have to go look after once I've woke up abit more.

what you need is super Steve...hes the fella to solve this...

I know Mike but don't think he's got round to me yet, he's too excited with that cracking new engine he's just bought.

And that Pete is trying to confuss me as to what engine it is, does he not know I'm on medication

Stu.

Yes it is a Mk12 sorry for the cofusion, it's my age

Stu.

Well new plug arrived but still the same problem, starts first pull and runs for a few seconds then dies away as if it was out of fuel, but there's plenty of fuel in it, give it another pull and away she goes again. You can start it up first pull every time but it just fades away. Any suggestions before I pull the flywheel off and how easy are they timed back up?

Stu.

PS It's still a Mk12

Sounds like a clogged jet, try running it with your hand over the intake.

Cheers Steve

It sounds like it is fuel starved.....blocked jet/ stuck float needle/blocked fuel line/fuel tap....
Timing is 3/16inch btdc..

Thanks think I'll pull the carb to bits before I do anything else. I have to agree it is like a fuel problem more then ignition.

Stu,

If you ran it on the choke it would cut out after a little while as the engine would be running to rich. Id go back to basics and see whats what before i striped the carb. Check the bolts/ nuts that hold the carb on are tight arnt they , if not they may be pulling air in and running to weak.
