Struggling to get 7 minutes a tank

[AndyG72]

Hi.
I’ve just got a Alpha Dragon 4 and after one 5 minute round my tanks pretty much empty, any ideas what I can do to improve this.
Someone tinkered with the tuning of it but cocked it up as they made me loose top end speed and during the race it ran like s**t and it needs to be richer.

where do you race?
Jon Dell is the Alpha UK team manager - if you can get to a meeting he's at, he should be able to get your engine running sweetly.

run a smaller venturi and shorten the throttle linkage slightly, you will need to retune slightly but it will mean that you are drawing less fuel as less is getting into the carb.

all this will mean a longer run time

more fuel filters and longer lines :P
