Re: Need some help, first MB
Let's see.....if you have throttle cable that is really crimped or damaged in some way, then that could cause the symptoms you mentioned. Then your only way out is to get a new cable.
If that's not the problem, then I'd have a look at the slide inside the carburetor.
Also you'll do well by reading these posts. A lot. You'll find the answers that you need sooner or later and you'll also pick up answers to questions that you don't even know you have yet.
Best of luck with it.
