Default Anyone know anything about 2 stroke petrols?

Yo people

My dad's got a 2 stroke strimmer (wheedwhacker) that just won't run. When you press the priming bulb, fuel just comes from the tank, through the carb, and back in again. He took the carb to bits, soaked it in white spirit, sprayed it through with compressed air, no dice. Same thing happens.

Anyone shed any light on it, or is the carb completely screwed?

can you post a video, that would make troubleshooting WAAAYYYY easier.

check for vaccum leaks, they will prevent the draw of fuel from the tank to the carb. spray either around the carb and if there is a bad seal, the either will be drawn into the combustion chamber and the engine will attempt to fire if there is a leak. also, how much compression does it have? try replacing the plug and clean the air filter. just covering the basics, outside of that, post a vid bro.

So how oid is this trimmer? If it's got lot's of time on it you would better off tosin' out. Things to look at are look closely at the primer for cracks. Get a fresh spark plug. I have seen them with cloged mufler never start. One bench trick is spray some carb cleaner to see if will fire. And make sure you've got spark. Good luck, but it's something to mess with on a rainy day.

So, turns out it was the carb. Sprayed a load more air in, and a lump of dirt when 'Pphhhhhhuuut!' and flew across the garden. Primed it up, and it fired first time.

I think it needs a fuel filter, I'll see what's available. Maybe one from a 1/5th scale RC would be good.

Nice to hear you got it sorted out. A pick up-clunck with filter from an 1/5 will be fine. I laughed a bit when reading 'Pphhhhhhuuut!'
