Status: offline 		Hey, im just about to throw my aftershock across the yard! Whenever I go to start the engine, the pullstart will work for a couple of pulls, but then it stops working. It feels as though it is slipping, but whenever I take apart the backplate assembly, everything looks fine, including the owb. has anyone had this problem on their truck, please help (I need to get it tuned soon because I have a big race to go to next weekend)

Status: offline 		It could be the one way, but i would look at this first, mine started doing the same thing after about six tanks of fuel, took the back plate off and there's a plastic gear that the starting shaft gear grabs onto to turn the motor over mine stripped out and now i have to use spin start, but i'm still using the same back plate just not the pull start. Good thing losi put the combo back plate on the aftershock

Status: offline 		Simple fix that usually works is after priming engine a little more than usual(Blowing through pressure line if still slipping), tilt truck so the pullstart is towards the ground and crankshaft is pointing up and let it sit for a few seconds. The fuel saturates the owb and washes off excess oil, and it usually grabs right away again. I have to do this if I don't completely run the fuel out and the oil thickens around the owb.

Status: offline 		I broke the nut on the spinstart backplate 3 times from using a drill, which i am guessing was too powerful.
