Seeing as how I'm all electric and have only so much as run a nitro a couple times, I could really use some help here! So this memorial day weekend my sister and brother-in-law came down to visit, and SURPRISE SURPRISE he brings his Revo 2.5. For starters, it looks like it's seen better days, the reverse module he tells me kept burning out and the rats in his garage had their way with the shift servo wire. He tells me about how he can't get it to run at all and doesn't have the time to figure it out, so I was appointed the task of either getting it going or parting out and selling it. He even mentioned that he already got a Rustler to replace it, so he's clearly given up on it. I'd rather say I've given my all before I give up and sell it. THE BASHMONKEY ACCEPTS THE TASK First order of duty is check the ez-start and glow plug. EZ-start: Check. Glow plug: Nada. Check the wire, rats had their way with that too. 2 days later, replacement wire arrives & gets installed. Glow plug: Check. Still won't start though. Visible air bubble in fuel line, doesn't move while cranking even while priming. Reset Hi/Low needles to factory: still nothing. Cleaned air filter: still nada. TIME TO PLAY OPERATION: ENGINE SURGERY Small can of air blast into carb: Brown gunk flies out and now carb is clear. Open up engine entirely, DEAR GOD SO MUCH BROWN GUNK!!! Clean off ALL engine parts and put em all back together (even made sure to taut all cooling head screws before tightening. Everything back together, crank it for a couple minutes and see fuel flowing in. My god it even started, idled for a minute but then died. Since then it's only come close to starting a few times. Any idea what I might've missed?
