Welcome to Andy's Model Engine Repair Website.
Model Airplane Engine Repairs and Reconditioning
I will repair or recondition any two or four-stroke model airplane engine, glow or gas, single or multi-cylinder. Four-stroke engines are my specialty. I can also do machine work and employ various welding methods if necessary for the repair. Such work as
the following can be done:
-Restoration of stuck and frozen old engines that are otherwise sound to good running condition (see photos)
-Bearing replacement, two or four stroke.
-New piston rings, including cylinder honing.
-Removal of frozen bolts or screws without damage to the engine.
-Complete engine rebuilding to restore performance.
-Damaged engine repair.
-Straightening of most single-cylinder gas two-stroke crankshafts,
and some others, depending on amount of the bend.
-Glow Plug 1/4"-32 thread restoration (Helicoil) in stripped cylinder heads, two -stroke or four-stroke. These are done on a straight labor-time basis with a $25 minimum, which is generally all it takes.
-I am not currently set up to do broken exhaust port repairs. Clarence Lee still does these using a threaded brass insert. Call him at 818-352-3766.
Since I have to buy them at retail just like you do, there is no
markup for parts and I will use yours if you have them (assuming they are correct). Shipping costs for parts is also a pass-through. Bearings
will come from Boca Bearing, other parts will be ordered from the
Labor for any skilled service is $25/hr, clean up using an ultrasonic cleaner is billed separately at $10/hr. A typical two-stroke bearing replacement in an
otherwise mechanically good engine will take about an hour or less, including light cleaning, plus roughly $15
to $30 for the bearings.
The cost of cleaning is impossible to predict but generally runs about $10.
Four stroke engines, by virtue of their far greater parts count, require more labor for almost any repair. A tear down and analysis of a typical four stroke will require close to an hour's labor depending on the make. Smaller engines (under 1.0 cu. in.) tend to be less cost-effective to recondition if corroded or frozen than larger ones since the labor is the same regardless of size, but the engine's value is much less
. Something straightforward like bearings, piston rings or a connecting rod replacement is pretty much the same regardless of size. Obviously there are more parts to clean in a four-stroke, running around $20 and up.
I will give you a rough estimate after seeing your engine, but I
don’t always know what I’ll find until its apart. Often an older engine that has not been used in a while, or has not been properly preserved for storage will be frozen and damaged by corrosion (especially four-strokes and even if you live in a very dry climate, (see photos) to the point that restoration of all the parts will require labor costs in excess of the engine's worth.
If I feel its not repairable, or the parts or labor cost will be excessive, I will not proceed further without discussion
Often its cheaper to replace than repair. If that is the case, you will only
owe me for my time to tear it down, generally less than an hour unless there are broken fasteners, etc.
A Money Order
seems to be the easiest and least costly way for most people to manage payment, at
least in my area. Our local supermarket charges $0.89, for example.
All work is guaranteed for a period of 90 days from receipt. (No comebacks to date.
Don't overheat or over rev your freshly repaired engine and expect me to fix it for free. I can tell when they've been abused!
