what do you think is the best engine to put on my avalancheto replace the sh 28. i want even more power. i know the sh.28 is powerful but i did not break it in properly. i only have 1/2 a gallon threw it .where i got it in my town he told me to just run 5 tanks of fuel threw it at no more than half throtel and that was it and im ready.so i thoght if he sells thim he must know what he was talking about. but i think i should have read the intructions and done little more reserch fist but being my fist rc i was ready to run it. acouple of times it got really hot i droped small drop of water around the glow plug and it was like it exloded.so it sat up 2 weeks with other problems after fixing the problem im ready to go again but will not start it started 2 times but died . ive tried new glow plug ajusting l/s h/s and idle like most of the other post said but nothing.[:@]
