Skip ahead to around 7:00 in the video.
I 28:1 for break-in and normal running.
Some guys have different opinion but this has always worked for me.
I like this oil:

I'm not familiar with that oil but if it's for dirt bikes it will be fine

Hi David. It could be any number of things from an improperly tuned carb, clogged air filter, fuel tank needs venting etc. Best to post on the forum at www.redcatrampageforum.com
There's some good carb tuning tips at the end of the above video.

Going through break in process, When I give truck a little throttle it sounds like it going to bog out

Is Lukas 2-stroke land and sea a good oil? I haven't used it yet but I have some and want to know if it's OK to use or should I buy different stuff?
