Paramotor essential toolkit

by Had Robinson
updated May 18, 2021

You have purchased a $6,000 paramotor and you are going to use $10 worth of tools (some screwdrivers and a pair of pump pliers) to work on it.  I hope this does not make sense.  Paramotors are not Toyota-engineered wonder-machines.  They are made mostly in small shops in Italy where incompetent and/or lazy workers cannot be fired and this makes quality control a serious problem.  I see enough of it in the engines that come in here.  But Italian engines can run at full throttle better than any others, so we put up with it.

These are the tools that you need to properly service most paramotors.

While the Harbor Freight tools listed below are not their professional (and more expensive line), they are more than adequate for the occasional mechanic.  Failure to use the proper tools is a guarantee that you will damage your engine.  Suffice it to say, there are some who lack basic mechanic-type skills or would rather not work on their engines.  In that case, contact a competent local mechanic who knows high performance 2 stroke engines.  These are almost always the chainsaw, kart racing, or dirt-bike guys.  If at all possible, find a kart racing engine expert.  The kart clubs are everywhere in the U.S. and these guys are the world experts on 2 stroke engines and the diaphragm carburetors used in paramotors.

The tools listed below that are available from Harbor Freight are followed by a stock number.  A few items are only available from auto parts stores, a specialty tool supplier, eBay, or Amazon.com.  The stock numbers, brands, etc. may change over time so pilots may have to do a little extra work to locate the tools listed here.  Often enough, these tools are on sale at HF, sometimes at 50% or more off.  The basic tool set will allow pilots to work on nearly everything except some parts of the ignition system, redrives, and the crankcase assembly.

Basic Tools

See the Fuel equipment for suggestions on the equipment needed to safely fill, drain, mix, and store fuel.

"*" = an essential but special tool used often

Air compressor with accessories #61615, #68260, #60356 (best) or a can of compressed gas used for removing dust
Air-tool oil #68094 – this oil is lightweight and contains no detergents or additives as does automobile engine oil.
Anti-seize lubricant – available from auto parts stores
Brake cleaner – this is required to remove grease, oil, and grime from parts before assembling.  Unfortunately, most auto parts stores only have the "non-chlorinated" versions which are next to useless, thanks to the enviro-nazis who spend their lives being busybodies and nitpickers.  If you do not live in the Happy Socialist Republics of New Jersey or California, you may be in luck as the chlorinated versions of common brake cleaner (a powerful degreaser) are still available.  Please remember to boycott volcanoes as they send 1,000 times as much VOC into the atmosphere every year as all VOC solvents manufactured during the last century.
Clutch puller Tool #MANEF (Top 80 only) – available from Miniplane-USA.  Most engines require special pullers.
Compression tester Kit 8 Pc #69885  If you have a flash starter on your engine, this tool will not work.
6 in. Digital Caliper with SAE and Metric Fractional Readings #68304  Professional calipers are more accurate but the HF ones are adequate.
7 Function Digital Multimeter #90899  It is an amazing value at $10 for its accuracy.  The more expensive ones are easier to use and tougher.
Permatex part #81950 Ultra Slick Engine assembly lube, 4 oz. – put on all sleeve bearings when assembling them.  In auto parts stores.
3/8" x 6" Extension – available singly from auto parts store but not from Harbor Freight
Fuel line – 1/4" and 1/8" OD fuel resistant fuel line.  Miniplane USA sells it by the foot (page down twice to see the fuel line)
White lithium Grease, small tube – available from auto parts stores.  I don't recommend the spray-can type.
16 oz. ball peen Hammer #61304
2.5 lb. dead-blow Hammer #69003
1500 Watt Dual Temperature Heat gun 572°/1112° #96289

*Ignition coil spark tester – this $10 tool will test every part of the ignition system except the spark plug

Technical Measuring set 6 Pc #94447
*Metering lever gauge for Walbro carburetors – the simple way to check the metering lever height.  If it's not correct, the engine will not go to WOT.
Needle File Set 12 Pc #00468
Penetrating oil
7 Pc Pliers set #69357
Puller set, bolt type #62620 – used to aid in the removal of propeller hubs

8 Pc Screwdriver set #94607
Chapman Screwdriver kit model #8900  – optional and available from Amazon or eBay, it is expensive precision set of tools.
Siphon for fuel transfer – see the Fuel equipment section.  A "jiggle-type" siphon is the easiest way to move fuel around.
 battery operated fuel Transfer pump – optional but at $10, a real bargain and time saver
6 Pc 3/8 in. drive metric hex Socket set #69546
21 Pc 1/4 in. drive metric high visibility Socket set #67998
20 Pc 3/8 in. drive metric High Visibility Socket set #67999
lead-free rosin core Solder #69378 – used to measure cylinder head/piston spacing (a.k.a. "squish")
Wright 9531 Spark plug gauge & Gap tool – Amazon's description is incorrect but it is the right tool and is available from other suppliers.

0.20 oz. semi-Permanent blue Threadlock #96059
0.20 oz. permanent red Threadlock #96055
Torch – either propane/MAPP or (better) oxyacetylene.  The latter is better because it delivers the maximum amount of heat the quickest, disturbing adjacent items less.

DO NOT USE TORQUE WRENCHES WITH ADAPTERS.
 3/8 in. Torque wrench click-type
 1/4 in. Torque wrench beam-type (preferred as it is more accurate than the click-type below)  OR

Please go to the bearing replacement page for these special tools.
