HPI Firestorm - tuning

[Mini1275]

Hello,
I have a nitro HPI Firestorm which hasn't run for a while and i'm going to get it out again but will it need re-tuning or should it run ok?, it's been away for about 4-5 months.
cheers

yes, will need a retune, if only for the change in temperature between summer and winter (albeit you wouldn't think it today)... I'd suggest you richen the HSN a bit (1/4 turn) and lean it off until it's punchy and you're left with a trail of blue smoke.

Good luck... also best to use after run oil in the motor if you're going to leave it standing for a month or so.
