Hi guys, My mini is doing an occastional miss. when I floor the throttle to the ground it sometimes misses. If i take my foot off the accellerator then reaply it, it will be fine! Any ideas?

try checking a few of the following, i had a similar problem

have you got enough dashpot oil in your su(if running su/s)?
if you dont have enoguh dashpot oil the mixture leans as soon as you flaten your foot making a flat spot or miss in some cases.

what is the condition of your condensor and points? its extremly inportant to replace the condensor everytime you replace the points, i have seem then die before creating a miss or in extreme cases completly stop the motor running.

are your spark plugs carboned up?

regards matt

Check your plug gaps are not too wide.
Should be .025" for stock ignition, but if running electronic you can open them up a bit. I set them to .032" with a Pulsar dizzy.

Watch it if buying blister packs of plugs, often they are gapped at 1.1mm for modern engines. You need to reset them.
