Hi Rob,
Can't explain what the thin pipe shown in your pic is. My F2 (tillotson) has the fuel pipe coming out of the fuel tank thru the filler cap, then thru the priming bulb. The only filter is a gauze in the carb itself. Sorry, I've tried 3 times to upload a pic but it keeps rejecting it although i've modified it each time.
I've never flown my F2 as the cage has some collateral from the prev owner, but the engine is beaut, so I'm ditching the fibreglass and building a conventional larger cage to take a F3 sized 115cm two-blade prop, as the original 4-blade is 300+ euros from born-prop.
Regards, Bob.
