FP is now discontinued for many years. I have the manual. Actually, it looks like I have several manuals to upload to my site. The FP are ringless ABC type, but probably have a nickel plated liner.

Email Hobby Services through the address at the bottom of the manuals page. I needed one for a FT240, had it in less than ten minutes. If they can't help you out, I should have the 40FSR manual at home.

thx.....yeah i already tried them. they respond very quickly, but apparently they have no info on engines that date back that far.

i have 2 of the 40FSR's that are NIB on the way from ebay sellers that should have the sheets.
problem is that they won't be here till next week, and as luck has it, there is a seller from up north that has some parts available. really hate to buy parts that may not be right.

OS 40FSR & 45FSR parts listing


Here's a list of parts for the OS 40 & 45 FSR engines I compiled from a 1984 World Engines parts catalog. I've put bold "Y"s in columns where that engine used only that specific part and a normal (not bold) "Y" where 2 different parts were used in the same engine designation. For example, where the 40FSR-S (stunt) and 40FSR both used only the 4.5mm wristpin #24806000 (bold "Y"), and the 40FSR ABC used only the 5mm wristpin #24806301 (bold "Y"), the 45FSR and 45FSR-H was made with both sizes (normal "Y" for both wristpins). These 2 sizes of wristpins complicates ordering replacement pistons, wristpins or conrods.

And, of course, there may well have been changes not reflected in the 1984 World Engines list.

The attached ZIP contains an XLS spreadsheet. If you can't read the XLS, here's a PDF.

Well guys, talking about the 40 FSR, here is a scan from the manuals from my engine. Also youŽll find the manual from the 4B carb (and 5 & 7B too..). Hope that these must be useful to the group
