P90 Semi Auto Problem

[Doc]

hey eveyone.

theres a problem with my TM p90. it only fires full auto. when ever i put it to semi, or depress the trigger halfway in full, it dosent shoot. does anyone know what could be causing this?

i am using a fully charged battery, so it isnt that.

there is a lever inside the mechbox, you can see it from outside of the mechbox... it's designed to throw the trigger connection out and break the circut when in semi auto, this may be related to your problem, on one end it runs to where the gears are i can't remember exactly but there is a egg shape on the gear that moves the lever... come to think of it this probably isn't your problem but it doesn't hurt to check.

my p90 is warn out and the gear timing landed perfectly so that lever just stopped my trigger all together and i couldn't fire at all, i just unscrewed the motor and took it out then spun the gears back to nutral. gun worked again. hasn't happened again yet..

maybe that lever is broken?

Iv had same/similar issue.

I have the same issue with my Echo 1 P90, and I believe it to be due to the cutoff lever.

That or look inside so see if the fire selector in the TM P90 bottom half shell is seated right.

I had a similar problem where the trigger would not shoot and that semi is full auto. I just took a flashlight and pushed that metal piece that follows along from the fire selector to the mechbox back into place.

Sounds like it's related to the cutoff lever or selector plate.
