have a Shindaiwa brand leaf blower that I think has steel lining or sleeves inside the cylinders and that these are rebuild able? my question is,,if it is still running good.but just getting blow by when not fully warmed up.is it very possible that I can just replace the rings only ?how much time to take in comparison to replacing pistons and whatever else? bearings, seals, etc?
yes they will come back every year i would know
if you invite the over they will come
If you did that much spraying it is not likely they will be back soonBut dont worry about it if you see them back again just re treat your spray and vacuum the ones you findThey wont hurt you they are either just trying to get out of the weather or they are looking for food.
I live on a farm nestled in the woodsWe see quite a few carpenter ants (and other bugs)I have to be careful what I use as far as chemicals on our farm because we are organicThe unsung properties of diatomaceous earth sounds like what you needTo ensure the critters do not come back get some food grade diatomaceous earth and outline the perimeters of your home inside and out with this stuffIt is all natural and VERY effectiveIt is made of fossils of a hard shelled algaeAll bugs abhor it because it absorbs moisture from the waxy exoskeletons quickly dehydrating the bugAlso super cheap compared to other products.
You won't know until you dismantle the engine, remove the pistons, and check for wear of the piston bores (cylinders) and especially of the piston ringsIf the bores are within tolerance then the next step is usually to fit the rings into the bore and measure the gap in the ringsHow big that should be depends upon the engine capacity Novices often end up breaking the brittle piston rings when they remove or replace them, and also often forget that fitting new piston rings MUST be accompanied by de-glazing and honing the bores You also need to be sure that it actually has piston rings: smaller displacement engines often have ringless ABC construction (Aluminium pistons, Brass cylinder liners, with Chromium cylinder plating)Or may have Nickasil cylinder liningsWith ABC/Nickasil constructionthe cylinder liners often have to be replaced when worn and they often come with matched pistons How much work and whether it's worth the cost depends upon your skill levels, what you find when you dismantle the engine, and how cheaply you can get the partsIt's a real How long is a piece of string? questionBut usually on cheap, no-name brands like Shindaiwa, there is little or no spare parts availability unless you can fabricate them yourself (making piston rings is a very skilled job) and it's often cheaper to recycle and replace, but if you know what you're doing you can often swap a worn out engine for another one of similar size if you can fabricate suitable adaptors to mount the engine and to match the output shaft to the to the leaf blower.
