check your shim you should be in the .6 range and if your running 30% you should be using cold plug, the restrictor plays a good role in the fuel milage and so does the pipe, you may want to consider retunning the engine, temp is not eh key to the tune but will give you an idea if your still on the rich side if your not familiar with the engines performance, I just go by sound and peformance dont go to lean but in general milage will increase if your not running rich, the number of cars i have seen on the local tracks according to the racer saying the performance is good, in my perspective they are abotu 3/4 out on the needle to race tune.

actually tons of bottom even with my servo slowed to 85. i pitted at 8 to get away from a lapped throttle jockey then came in again at 19 then ran the main out. if you want to try it lemme know you can borrow it if you want. i also want to try the 2060 on it this weekend.

I am going to try the 2050 and see what that does. I would like to know how the 2060 does and may want to try the Losi pipe.

Another vote for the RE11. I get 10+ minutes out of my Go 7-port .21 in my truggy. lol.

Fuel mileage is a complex equation, but I can narrow it down to the 3 most important factors (IMO 
).
1. Conservative crank and port timing with a docile sleeve configuration will provide better fuel economy.
2. Driver. The driver needs to be calculated and not excited. A smooth finger will gain mileage.
3. Tune. You can't be fat...
Nitro and oil content play a factor, but you can go the distance with most of the low oil content 30% fuels on the market these days, if you have the above 3 items figured out.

rfleck and i race together and he was the first to make the 10min heat with no pit stops. i did give him a hard time about the 4 feet of fuel line in his car, but had to shut up when it teched dead on at 125cc. but both of us can make the 10 minute heats. i use the stock 8mm restrictor and can get full throttel if i need it, i'm not sure what restrictor ron is using
I WAS getting 12 on the old layout with 7mm restrictor, Dynamite 053 pipe... but can barely make 9 on the "full wood" track layout they have now at Indy.
(Ron and I run VSPECS, forgot what Doug runs, but I think he has something similar...)

i guess the question should be asked if you are running a buggy or a truggy when it comes to how long it will run. it is deceving when guys say they can get 12 minutes without letting you know it's in a truggy that has a 25cc larger tank then us buggy users.

If you get the correct pipe either the Nova pipe recommended for it or something close that will be a huge help. I was at one of the local tracks in vegas helping Drake while we tuned and tested runtime on that engine. His was fairly new at maybe 1/2-3/4 gallon and with a 7mm, temping about 230ish and he was going over 10 minutes.
With his plus 4's he was doing 12 and on the silverstate track he was getting about 10:45
So it's just a matter of a proper tune, the correct pipe, and decent fuel(some get more mileage than others).
So try either the nova pipe, what black said, or the new losi pipe..
