Ok, hopefully someone can shed a little light for me. I have a 4309 revo with 3.3, long story short broke Conrod . I ended up purchasing a new os .21 tm ( which was basically a direct drop in) got it in and all bolted up with new clutch, clutch bell , fuel lines, fuel filter, tank, lc3 plug, 20% sidewinder fuel
I took the truck out today to break the motor in. Weather was kind of mild at around 65 if this even matters. I preheated the block up to about 160*, primed the fuel, took it outside and it fired right up on 1st hit. AWESOME! The truck pretty much will take off on its own if I don't hold the brake and the temps jumped up to 260 ish with the quickness so I immediately richened it up a half turn. From reading about break in procedures most say 190 to 220. So I was worried
So I take it out and run at 1/4 throttle for a tank and bring it in and let it cool down for 15mins. Try to start it up and nothing. Keep trying and finally get it to fire but have to give it gas.... For this run i put it back to factory settings and give 1/2 throttle. Temps still too high for my liking but what ever. It's pig rich and fuel is all over the rear control arm and lots of smoke.
As more tanks go by its just more of the same. I incorporated some of os breakin procedure as well by leaning hsn 30* or 1 hr increments per tank. Still dumb hot into 300's and spewing raw fuel.
Btw factory settings were all needles flush..... And guy I bought this expensive pita from at the Lhs told me not to worry about sealing it up because o.s. is top of the line.
Does anyone have any ideas about what's going on. Hopefully is not toast already . Thanks
