JLO Engines (ILO)
Brief History of the JLO Engine
JLO (also spelled ILO) is a German engine manufacturer now owned by North American Rockwell Co.
These engines have been used by many marques including Anker, Bastert, Batavus, Bauer, BM, Bismarck, Bucker, Diamant, DMF, Express, Gazelle, Glas Goggo, Goricke, Hercules, Hoffmann, Lion-Rapide, Lohner, Maico, Mars, Meister, Minimo, Monark, Panther (DE), Rabeneick, Rixe, Santamaria, Sparta, Tempo, Tornax, U T & Universal.
Swedish Maraton mopeds were fitted with JLO.
Many snowmobiles including Arctic Cat & Polaris used ILO engines, as did go-karts including the 1960 Trokart. Outboard manufacturers employing JLO included Warrenjet, and another marine application was the Waverunner.

2f-340 Engine Differences
Greetings! I hope that you can help me--I am working on a vintage snowmobile for a friend and am trying to determine the differences between JLO/Rockwell engines in these models to determine which parts are interchangeable.
Can you tell me what the different suffices in engine models mean? For instance, what is the difference between a JLO 2f-340-1 and a JLO 2f-340-6? I can find head and cylinder gaskets for the former, but cannot find any docmentation nor any parts referring to -6 engines, or any others for that matter.
Would the top end gaskets from one be interchangeable with another?
Thanks very much!

Rockwell jlo l295l
I have bought a hoverover hovercraft which has 3 rockwell engines. The main one is a JLO L295L which is the one I have questions about. The engine was in pieces when i got it. I have bought a new piston and conrod but the gudgeon pin is too small for the conrod. Is there meant to be a roller bearing on the small end of the conrod??
Also, what petrol mix are these engines supposed to run on?

Bad running/won't run
JLO Outboard Motor 76cc (Amal carb).
This motor is giving a lot of trouble. I cleaned the carb and added new fuel. There is a good spark and the motor did run once for about 30 seconds then failed. Cleaned the carb again but still no go. I think I will have to dismantle it to check piston rings and crankcase seals. Can you advise what the compression pressure should be? Best regards from Dave.
