Scooterotica

I've been having a lot of trouble recently with the engine being starved of fuel. I thought I'd got to the bottom of it when I found flakes of liner in the tank. Fitted another tank and for a while it seemed to do the trick. But now it's up to its old tricks again. Doesn't want to go. Fuel pipe nearly empty and starved of fuel. I don't get it, and frankly I've got nothing more to offer on this. I just don't understand why it's not drawing fuel.

Casa 185 kit
22mm Dell'orto carb
Standard exhaust

Fuel tap is good. All appears tight. Petrol cap on or off makes no difference. Clutching at straws but would a standard exhaust create too much back pressure that prevents the flow? You can tell it's getting to me because I was giving admiring looks to a 4t LML 200 last night. Somebody save me from eternal hell fire and damnation.

Nev, have you stripped down the, I presume, fast flow fuel tap to check there's nothing in there from your petseal coming away? If so, I'd check the flow rate through the tap. If that's OK, then carb strip and get an air duster and blow through all jets/orifices, check float height. After that I'm bolloxed.

Did that Mark, and now can't remember which way it goes back together. Lucky I had a spare fuel tap. I've had the carb on and off. Jets should be good. Not sure about the float. Not a lot to go wrong on a 22mm carb though.

nev john was very concerned last night when he saw you looking at that LML!!!!!
you wouldnt would you?? :-0

I might. They are good old buses by all accounts. Sometimes you just want something that goes.

Try another carb which will narrow down the problem, I have a spare if you can't borrow one more local.

Have you tried another fuel tap? I had a new one that was faulty from the go last year.

Check the breather in the cap or just change it.

I have another carb to try thank you Tim. I've tried another good tap Glynn. Same difference. I've also swapped the petrol cap Soosh and tried it without one. Baffling!

might be a long shot but have you checked to see if the petrol leaver it not spinning on the metal arm
which goes to the tap,had this happen on mine a couple of months ago,you think its turned on fully
but its not so the float bowl becomes empty very quick..Just a thought
