C1 cat
Hey guys I have just got a kyosho Lamborghini c-1 cat with a gxr28mr
In it although I have some knowledge in nitro engines n have done
The basics eg. Change glow plug fuel/air filter, new fuel. I have
Attempted to reset the needles but still no luck.
High speed needle 2 n a half to 3 Turn clockwise n idle needle about
.5 mm from close.
When I got it I was told its a runna but to no surprise it's a no goa hahaha
Does any body have any idea what the factory setting I can only find
The instructions in japaneses and that no help to me
Thx heaps inadvance

RE: C1 cat
Have you got the plastic or fiberglass version? Not that it matters in this case but just curious.
General rules of thumb for getting the engine up and running but probably not correctly as that depends on a ton of other factors.
Usually Rule #! is NOT to mess with the low-speed needle on nitro boats even though the carb has the ability to let you. Take that needle out to where it is even with the nut or the end just before it starts to stick out.
The high-speed needle you should be in the neighborhood but it sounds like you did it the wrong way according to the way you typed it up. Bottom the needle out but don't tighten! Bring it back out 3 to 3-1/2 turns as that should also be a rough setting.
Hopefully you can start it with those settings. The problem is that you can't get a true carb setting until it's been in the water. On land, you can blip the throttle (NO wide open revving unless you like buying parts!), if it has a slight lag to it, you're close. If it revs right up then it's lean.
Don't expect a lot from it. Radio Control Boat Modeler magazine did an article on it and if you read between the lines, it wasn't exactly a glowing review. The trim tabs/turn fins were a Band-Aid fix for its ill-handling.
