well i put a new plug in. Ive had to buy them from my hobby store and the guy never ask what kind i want he just always hands me the same kind. it said McCoy MC-9. I geuss thats the type of plug it says it in the top right corner. If thats what it is then i bet thats the problem because this car runs like crap it runs the same no matter how i tune it. From the low even with the collar to a full turn in, not a bit of a change. Same old bog. One thing tho is that like i said its my freinds car. He lost most his interest so i kinda took over working with it. He let it sit like around 2 weeks with no after run oil!!! And it still runs it never shuts off like a rusted motor or anything like that. And thats not the reason it bogs it bogged like that before he let it sit so long. So i might hafta order some plugs off the internet. Im using the same plugs in my tsunami and it runs fine. Should i get new ones for that car too?
