help 2.5r won't start

[gearjammer8]

I have a trx 2.5r PULL START on my traxxas t-maxx. Every time I go to use it it won't start. I've changed the plug and sometimes I will get lucky and it will fire. I'll run it up and down the street a couple times trying to adjust the carb cause it runs like crap. After about 4 or 5 runs it just won't start. I get tired of trying to pull start it so eventually give up. Any ideas on what to do?

These things don't automatically run right all the time. You need to properly adjust the tune on the carb.

Print out the flow chart and take it with you when you have the car out for the next run.
