Fuel Question

Re: Fuel Question
Don't know if there was a Factory Recommendation for Fuel/Oil mixtures for these early engines. Here is a little information on Cameron :

Re: Fuel Question
I have a manual, it only says to use Thimble Drome fuel and a little extra oil for break in. One thing interesting is you could get gears for a different drive ratio.

Re: 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


Thanks Dredd

Re: Fuel Question
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.
