    I have a Shindaiwa hand-held eb240 blower. It starts up easy when the engine is cold. But If I turn it off for a few minutes, it's very difficult to re-start. Any idea what the problem is? thanks

    You failed to mention how old it was or how long since last service so I'd start with the usual--check for spark when it won't restart. If no spark likely a bad coil. If you have spark, check for compression and if not at least 90psi you will likely experience hard starting when unit is hot. If compression is good do the usual things--new plug, new intank fuel filter, clean air filter. When you have it running when initially starting it, spray carb/choke cleaner around the base of the piston jug, isoblock to jug and carb to isoblock. If rpm's change likely have a cracked isoblock or jug gasket leak. You may also want to check this also while the unit is hot before you shut it off. You may also want to pull the muffler and check for any galling of the cylinder/piston resulting from a possible weak oil/gas mix or straight gas condition.

    I recently had the cracked isoblock condition(not a Shindiawa) where the crack was on the bottom and it acted exactly as yours did. When cold the crack was small enough to allow starting but when hot it expanded allowing excess air thereby allowing an extremely lean oil/gas mix.

    Just some thoughts--your mileage may vary.

    I've got the same blower.
    Warm and hot starts are not its' speciality.
    It seems like some carb adjustments would be able to clear things up.
    It's almost to the point that I'm about to get some torch tip cleaners and widen the jet.

    Don't know how old your 240 is but it likely has a nonadjustable Zama rotary carb.

    My 240 is 6 years and have never had a starting problem, hot or cold.

    A carb rebuild may be in order.

    Mine is about 4 years old. It's not really used a lot. I mostly use the back pack blower.
