Burned through a quart with the crt .5 today. Car ran great, no break downs. But I notice the tune leans out when the tank gets low. Would adding more fuel line help with that all?

Shorten the line from pipe to tank and youd get more pressure in there, might help.

if it’s the jammin picco red dot these are the settings based on info from another thread.
The factory settings of the engine are as following and are a good starting point for you. Turn in the needles completely (Caution: Do not
over tighten them!) and loosen them the required number of turns:
Idle screw: Should be open 0.5-1.0mm.
Low speed needle: Should be open: 6,75 turns
High speed needle:Should be open 5,00 turns
CARBURATING PICCO ENGINES
Engine works better on the rich side (HSN) and normally needs more than a couple of laps to reach the operational temp. Start on the rich side (HSN) and after 4 or 5 laps tune the engine. Doing this process on the bench (or starter box) normally overheats the engine driving you to a wrong tuning and maybe causing a damage. Set the engine a little bit rich (if you progressively open the carb, the engine responds quick but at 3/4 rpm becomes rich (not really 4 stroking but rich) Then at the track after several laps (at least 5) if the engine is still rich lean it.
Regarding LSN, Run the LSN a little bit on the rich side and still keeping the engine with a good idle (Very low rpm idle, is better for fuel consumption and handling of the car after off throttle).
After pre-heating the engine, just pinch the fuel line and if the rpm remains the same for 4 to 5 seconds and then the engine revs up and shuts off, that’s the best setting for a large track with long straight away. If the track is really short, and full of hairpins, LSN needs to be more lean, because the engine never revs up for a lot of time, and so if you keep the same setup described before it is always rich out of the corner.

I know we who have these CRT love them so i thought I would share mine. I purchased the kit new and have had it ever since.
I still run it on occasion. Was ripping the little jewel last week. They are great trucks!!
