Does the Hitachi RB24E Hand Held Blower need the stroke oil

The engine gets hot, and the smell is likely not anything to worry about.

If this is a hand held machine. It doesn't require engine oil changing.!

Although its a 4 cycle engine. its basically a 2 stroke engine with valves. It runs on the same fuel/ oil mix as a normal 2stroke engine. 50:1

If its a hand held Vac/Blower then I don't know of any that aren't 2 stroke.

Your part number isn't much help, you're welcome to post a picture of it. As I say, if its handheld and petrol then it will be a 2 stroke. Mix ratio is generally 50:1 That's 100ml of oil in 5L of petrol. Some manufacturers use a ratio of 40:1 which if used in the wrong machine can seize the engine, doing more damage, so stick to the 50:1 ratio to be on the safe side.

Anywhere between 25:1 and 50:1

I use one of those small 2.6 oz oil containers in a gallon (128 oz) to give a 50:1 mix. If you want more oil in your mix add another container - but it will be more expensive and waste oil.

Two-stroke oil with a 50:1 (Gas:Oil) mix ratio is required for the Husqvarna 125B leaf blower. Using the wrong oil or improper mixture ratio can drastically affect the performance of the leaf blower.

The best mix to use is what's recommended in the manual but in most cases blowers use a 50:1 mix. The difference from 40:1 to 50:1 is negligible but you have to use what the motor is built for. Too much oil causes a loss of power because the gas won't burn efficiently. Too little oil and you risk damaging your piston or cylinder.

If you have tried a new spark plug and you still have no spark, then your Ignition Coil, (Module) has gone bad. They aren't cheap if you buy it new. Try to find a used one if you can for around $10.

Good Luck!

If the carburetor screws havent been messed with it more than likely nees a carb kit

leaf blowers have a two stroke engine, so they need the oil mixed in the gas. so use two stroke engine oil mixed with the fuel. hope this helps
