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 or eBay.  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 from computer keyboards
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 weak.  Search eBay for the chlorinated versions of brake cleaner which are still available.
Chain wrench (optional) – this tool is essential if you regularly work on small engines.  Available from Irwin, this special Vise-Grip tool tool holds anything round without damage.  eBay also has used ones at a very good price.  Do not purchase the Chinese imitations which are very poor quality.
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)
