Thanks for helping me troubleshoot Pirate. I figured out which one was the return. The fuel leak has "slowed down" over the past day so I am thinking wherever it is, it involves a gasket since it is probably saturated now with the mix causing the leak to slow up a bit. My best guess is it is where the carb assembly meets the engine? That seems to be where all of my problems are....in the entire carb assembly. I also figured out how the metal end of the throttle cable slides into the channel that is cut in the piviot. To better explain the action of the throttle pivot, even with the cable removed it "rachets" instead of moving fluidly back and forth. Also, if I barely push up on the air cleaner plastic cover when everything is assembled, the whole back end lifts up (even after retorquing the connecting screws) more than it "should and the engine revs higher - I'm thinking it is allowing air in making the engine wind up and then almost completely shutting down. I can fix that part with creative rigging, but the throttle pivot was shot out of the box. I put an email into monsterscooter to see if they SELL the entire carb assembly, but haven't heard anything. I don't want to give up, but I don't want to sink much money into an engine that isn't worth saving. I think mine is just a dud, but it is becoming an expensive mistake.

The BMP kit is a whole other story....the quality and thought that went into the design, build and instructions is great. It is nice to know that there are small companies like that out there that take pride in their work, service and craftsmanship. You can tell that they didn't just throw something in a box to make a sale.

I'll keep you guys updated on what's going on. I did a s&^t ton of research on what to buy, and it fit my budget for this project, but after the problems that I have had, I wish I had put this $ towards a better motor. Andy you hit the nail on the head...I was looking for a "decent quality" Chinese motor, and I thought I was sacrificing "longevity" in doing so, but I expected to have more than one short ride on the thing. I am a crafty and determined SOB so I haven't given up yet...just frustrated

Here is a photo of my engine with the covers removed. I have checked everywhere and, so far anyway, no oil or gas leaks. I like the way this looks without all the plastic and I may leave it this way. It has plenty of cooling fin area and, since this engine is moving most of the time and not stationary as in a pump application, the cooling should be fine.

Have you checked back with Monster scooter at all on your problems? I know they say all sales final but, they really might want an opportunity to make good on this. Worth a shot.

That looks great w/o the covers - I had mine looking like that last night. Here is the update...Two more emails to monsterscooter and I have heard nothing. I explained my issue and asked could I BUY an entire carb assembly from them and got no reply. I in no way suggested I wanted anything for free or discounted, but I did let them know the issues that I have had right out of the box. I'm not two pleased with their service at this point b/c I just wanted to see if I could PURCHASE something to make this thing run the way it should from the get-go. Anyhow, last night I began to take everything apart. After stripping off all the covers I decided to fire it up and just take a look around to see if I could see any leaks or other issues.

1) In the picture that you supplied Pirate, the black plastic portion that connects the carb assembly to the motor, I happened to look down and notice that even though one of the gold screws with washers was "tight" the washers were vibrating around it freely. Took carb off and re-ran those bolts in straight....FIXed the problem of the motor surging b/c air was leaking in on the back of the carb assembly feeding the motor more air allowing it to surge and stay there momentarily. One problem fixed!!!!

2) Bent the metal with pliers that houses the cable for the throttle on the engine to "line it up" better so that the ratcheting action is reduced....it is still there, but it is doable. I just fear that this is going to break soon. I figured that I have nothing to loose "moding" this thing b/c monsterscooter isn't going to provide support.

So it runs pretty good now and doesn't leak as far as I can see. I think the remainder of the gas that was in the carb was leaking out b/c of that loose bolt. I wonder if the HF motor uses the same carb assembly...if it does, I plan on ordering one (along with an extra pull start, and clutch) from there and wait the 4-6 weeks. I'll have to ask Porkchop when I get a chance if he thinks it is the same carb.

One step closer to getting this thing right!!!

Good going fixing the air intake leak. Sorry to hear about Monster Scooter's lack of response. The contact I had over there, I believe, is named Jennifer. She was helpful to me for whatever that is worth.

Yes, Porkchop is the guy to ask about the carbs, etc. as he has both engines I think. He sent me a clutch he got from HF and it is identical to the one on this engine. He posted close-ups of his engine and, I swear it appears the exact same as mine, probably from the same factory. I think those pictures are in the 2 stroke engine topic area. Parts for this engine are dirt cheap from HF, just takes a while as you know.

Let us know what you find out from him.

Best of luck on getting this all fixed up.
