just filled up tank put 2 caps (oil) in tank gave a good shake, its been playing up for a wile trying to start it but clean'd out the air filter and fuel filter. now will only run with half choke. checked spark plug works ok with a good spark, the only difference is i got the fuel from esso, had been getting from tesco's before. there is no banging could it be the fuel???

What are we talking about here? Moped? Strimmer? Omega?

Sorry strimmer, was a pain to start before but when it warm'd up it was fine.
-
My petrol angle grinder used to only run with choke in variable postion depending on what rpm I wanted to do.
Removed carb, stripped it down soaked in carb cleaner overnight. reassembled and hey presto back to working well. Unless I get the oil/fuel mix to far out, I only do it by eye ::)
-
Yep, sounds like the carb jets are gummed up to me and it's running on the choke circuit.
-
just got it in bit's, bloody trox bolts on it gone through 2 trox's getting it apart, exhaust gasket has had it so making a new one later, carb looks clean but as said will leave it over night in some cleaner, hope my genny is ok as well not used it for awile, i will see if that sorts it out, only put a new head and bearing on the strimmer head last week.

The fuel/oil ratio on strimmers, genny's, etc is normally 50:1 (so that is 100ml of oil to 5 litres of petrol).

Indeed, and, thinking about it, depending what you define to be a "capful" (I don't know? 10-20ml) you might be over-dosing it with oil, which won't help matters.
I tend to mix up a 5L fuel can of it, which you can do with a smaller margin of error. Takes a while to get through it, mind, and some say you shouldn't keep it too long mixed. :-\

I bought a litremixing bottle as I have a variety of machines that use 25:1, 40: 1 and so on. £2.50 off Ebay.
It is best to use new fuel. I used to think it was tosh that petrol could "go off" stored in a can. Now I am not so sure!!

I have no doubt that it does go off. Just wondering if mixed 2 stroke is worse?
I also bought a mixing bottle (machine mart). Seems the plastic it was made of didn't agree with petrol because it disintegrated the first time I used it. >:(

its the mixing cap that fits the strimmer, any way put some air on it this morning and put back together and it working great now, started first time, running alot better, Thanks every one.

i used an old can of petrol for chain saw mix been in the can can for over 2years. needed to burn some hedge cutting, so thought to use it up and put a bit on to get it started. well not doing that again, lit the match put it on the petrol BOOM blow me side ways, every one in the hole street open'd there windows to see what was going on. and the fire never even started just a big Boom, well not doing that again...

I have always thought it bordering on the miraculous that 2 stroke engines actually run without siezing. Revving their nuts of,with just a dribble of oil mixed with the petrol to lubricate the crank bearings,bore,small end etc. It shouldnt really work but it does.
The quality of the oil has improved greatly though since the advent of synthetic oils.
I (along with many others of my age group) still habitually tend to ride a motorbike with the fingers of my left hand hung over the clutch lever,as it was often necessary to pull the clutch in sharpish on 70,s 2 strokes when you felt the engine start to tighten up. ;D

Been there a few times in my younger days! ::) My first bike, a Yamaha DT50MX, used to seize up about once every 2 months! Bugger is was quick though!! ;D
Funnily enough, I still ride with 2 fingers over the clutch lever. Never really thought about it until now! :y

You now officially qualify as an old biker Twigs. :P ;D

As a young teenager I had loads of bikes for tracking. One was a BSA Bantam. The throttle cable snapped so I slipped it over the frame beind the tank and attached it to the rear brake pedal(having disconn'd the rear brake). The clutch cable always jumped out of the socket unless you permanently rode holding the slack. Our neighbour who was old enough to go on public roads and had a 650 bike asked if he could borrow my bike. I explained the workings and pointed out the front brake was very good! Be careful.
What happened was best explained by the lady riding the horse. A speeding m'bike appeared, saw me and went to slow down. But accelerated, went to use the clutch and it had dropped out of the socket so applied the only thing left the front brake which pitched him off the bike. ;D ;D
