I have a Homelite Gas Weed Eater. Model BC800. What type of oil does it take and what is the correct mixture of gas to oil?

Try switching to MotoMix fuel. Its high octane and premixed.

Want to give us a hint as to what kind of weed Eater this is? Most gas models use a mixture but the ratio can vary between manufacturers.

??? Take a gallon gas can, pour the I/2 gallon oil/gas mixture into it and then add the correct amount of undiluted gasoline to the correct mixture. For instance, if you need a .2 oz/I/2 gal ratio then add 1/2 gal gas to what you already have. Remember, it is always better to have a little too much oil than gas.

Did you check the muffler exhaust or spark arrester, to see if it is clogged from using to rich a oil/gas mixture ? Did you replace the diaphragm in correct position ? Find a new carb online, possibly ebay ?

I found the manual for this model weed eater, according to the manual the mixture...
and I quote "This engine is certified to operate on unleaded gasoline. Before operation, gasoline
must be mixed with a good quality synthetic 2-cycle air cooled engine oil designed to be
mixed at a Ratio of 40:1 ...." and I quote once more from the manual "Helpful Tip. To obtain
correct oil mix ration, pour 3.2 ounces of 2 cycle synthetic oil into one gallon of fresh gas."

Hope that helps,
If you like I can send the manual via email if you need it.

:) happy weed thrashing

Check your manual for the proper gas-and-oil mixture. For almost all modern two-stroke engines, a 50-to-1 mixture is recommended. That requires about 2 1/2 oz. oil for every gallon of gasoline.

2 cycle? then 40:1 gas to oil mixture

what is the gas oil mixture for twist n edge 244cc gas weed eater?

Check your fuel mixture and remove the spark plug and clean it.

At any home store, wallmart or HDW you can find a 3.2 oz. bottle 2cyl oil for a one gallon of gas and not have to guess. That would be a 50:1 mixture
