Loquin's post has two pdf forms on it. One is an owner's manual that for some reason my computer will not download.
The first half of the manual is in Japanese.
Possibly your copy of adobe doesn't have the right font installed.
When I get the chance, I'll print the manual, scan it, then convert the English portion to PDF using just English font.
Meanwhile, see if it downloads properly from
here
The other is from the engineers at Mitsubishi Heavy Industries who developed the "Stratified Scavenging System" that allowed the TLE 26cc up to but not including the TLE 43 to be CARB authorized. I believe the 43 was built to the same spec.s and was later CARB authorized but I am not sure about that. The form mentions the TLE 43 and shows a picture of it as one of the test engines.
The report documented the experiments done using the 26CC engine as a test platform. After it was established that their stratified scavenging idea was feasible, they then developed the TLE series of engines. At the time the report was written (Oct. 2001,) all the engines except the TLE-43 had already been certified; and the TLE43 was in the process of certification. It shows up as approved in the 2002 CARB registry database, but at the time, it was
probably a provisional approval; the CO and particulate matter data wasn't certified yet. However, all the other TLE engines did have all the report data, and all were certified. It took several years for all the test data to get certified. I would guess that CARB required them to retest the 43cc engine for some reason. Maybe all the "i's" weren't dotted.
They used 50/1 ratio mix but do not state whether it was mineral or synthetic. I bought mine from Viza but could not get an answer as to where they got their info. Kirf and Pete say 40. The manufacturer and developing engineers say 50. Guess I'll use the latest Tanaka oil at 45/1. The Chinese say this is the year of the rat and the Japanese say I was born in the month of the rat(Feb.). Never argue with a conered old, oil-soaked dirty rat on a motored bicycle. Unless you are a great BIG cat!
LOL. I played defensive tackle in college - does that count???
The report states 50:1, as does the manual. When I bought the engine from Dave Stanton, he recommended 40:1 for the first thousand miles or so, then 50:1.
