Hi, I accidentally filled my chainsaw fuel tank with oil and put the fuel in the lube tank. I tried to start the saw and of course it wouldn't. Then I realised the error and emptied both tanks. Then I refilled them with the correct mix and now the saw wont start. Checked the fuel filter/fuel lines and they are OK. It seems no oil made it to the carb. Any ideas as to why it wont go?
Thanks.

Thanks Ben Helpful advice it worked despite attempting to start it previously with tank full of oil.

Clean the spark plug with petrol,spray damp start in plug hole and pull a few times with no plug.Spray a little blast in plughole replace spark plug and start.You may have to clean plug few times but it will start and after a bit of smoking run fine again.This is a lot faster than taking everything apart.Don't forget to wash tank out first with petrol and refill with 50:1 mix!

Well you need to flush out the fuel filter of the lub oil and the fuel line. You will also need to get the oil out of the carburetor if it had a chance to suck it up. The best thing to do is get yourself some carburetor cleaner and start cleaning. If you take the carb apart make sure you know how it came apart so you put it back together. You might have also fouled the plug if the oil got that far. If it did put a new plug (it might take 1 or 2) and when you get it running it WILL smoke but it will go away eventually.
