Fuel Question

Thanks for your reply. I went out this morning to an RC shop and got some fuel and fuel line. You answered a question a couple of weeks ago about where to get a needle valve for this engine and it arrived this morning though it doesn't seem to fit. I'm wondering if you have any suggestions of how to get it to fit or it I'm doing something wrong.
Thanks Dredd

I am having trouble with macro photo, measurements of mine.
length 38.78mm
barrel nut dia  4.8mm
shaft dia 1.51mm

Here are my measurements.

The threads on the end of the spray bar in your photo look damaged, could the hole be obstructed? A 1/16 (1.57mm) drill bit will slide into my spraybar and is pretty tight.

Mecoa purchased Cameron, they show engines and parts.

I believe this is the needle and spray bar

What displacement is your engine .09 or .15? Mine is a .19, it is possible the .09 had a smaller spay bar. Don't know. Could enlarge spray bar with drill bit also.

I've put a drill bit into it and it goes approximately 2.0-2.1 mm past the hole in the middle from the threaded end. I would assume the engine is the one in the pic on their website. Would the the whole bar on their site work?
Thanks again
