As you know, these engines are really basic. No distributor, no camshaft timing, valve lash or settings, nothing like that. So, if the engine was running and will not start the first place I would look at is either fuel system or ignition. I know that sounds simple but it can drive you crazy,too. Assuming something majorly catastrophic didn't happen to the engine (burning a piston, seizing it, hydrolock, etc. Check to see if you have a good strong spark. The coil can go bad and still have a weak spark. You will know when you check it if its ok or not. Make sure your coils is not grounding out somehow, maybe a wire rubbing up against something. Check your plug to see if its ok, not running rich or lean, check to see if its wet. Assuming you do all that and still no soap, it is a fuel problem, plain and simple. Take a good look at your fuel lines, make sure that they are not pinched somewhere and you are getting fuel. An easy way to check is to take the fuel lines off, blow into the pressure fitting and see if you have a steady stream of gas coming out. (be sure your somewhere where fumes are not a problem, though) If, you have a steady stream of gas then take a look at the carb. Is it on tight, does the gasket look ok, is there a possibility of dirt in the carb (it only takes a speck of something to shut these engines down RIGHT NOW. I would probably disassemble it and clean it all out. They are not difficult and it sounds like you have probably done it a few times.

If all else fails, go right back to square one with the settings. I keep a record (written) of all of my gas boats settings, fuel type, oil mixture, etc so I can go back if something goes wrong. I guess I get that from my open wheel racing days.

Hope this helps,
Pete

Status: offline 		Thanks for the help.

I've tried several things. Most recently, I just pulled the engine out and put back the stock and it fired up on 1-2 pulls so it's not the fuel or the fuel system. I pulled the spark plug and there is a spark (don't know if it's weak) but this is an engine that isn't even a week old. I have cleaned the carb with gummout carb cleaner but not actually taken it apart. There were no major catastrophies with the engine. I just ran it twice. The second time it was difficult to start and now I can't start it at all. I'm at a bit of a loss because I have many of these engines and none of them have given me this much trouble especially in just a week. I guess I'll take the carb apart next to look for blockage.

Status: offline 		that would be your best bet, like I said, put your finger up to the carb, and pull it a couple of times, if your finger doesnt have gas on it, it isnt getting gas, and the carb has something blocking it. another idea, when you installed the kwa, did you hook the lines up correctly, if they are backwards, it will not run, at least from what i can see thats the case...at this point it sounds like a fuel delivery problem.

Status: offline 		Well, I have good news finally. Mine ran with no problems finally. But now that it's running where it should be...I wanna go faster. 35-38mph would be where I'm at fully stock. But now after reading xxxtcr's log on his hull, I don't know how much faster I should go. If the hull is gonna split at 45mph...?? I'd be willing to hand my hull off to someone who can make the exact model we got in a good strong layup. My hull can be the plug. Hey Dreamin...you up for a building the "dreamin C1"? Or is there a copyright law against this?

LOL, I'm certain a few eyebrows would be raised, but thanks for the compliment.

It looks wider, or at least lower than my BJ55. Now THAT is a boat that needs to be a bit wider! It looks like it wants to topple over just sitting there lol.

Status: offline 		Just curious, anybody else out there other than Venomous with the upgraded KWA engine?

As for me, I'm going to run the stock engine for a little (that meanse about a day) before I go back to getting my KWA to work. It definitely kicked a when I first put it in but I'll have to work through some starting troubles for now.

Wondering if anyone else has any difficulty starting it? I definitely have no problems starting the stock engine 1-2 pulls and it's running and stays running.

The KWA and the Sikk are the same engines but one thing that I did notice is that their prices on parts are cheaper than what Sikk parts sellers are charging. I can get them through my LHS's also ehich helps a lot in getting them, a big plus for me.

Ron, I looked through last 12 pages looking for deleted posts, coulden't find one of yours that I deleted.

I've heard as well that the KWA and Sikk engines are the same.

Status: offline 		Looking for some info from you guys on modified engines.

The KWA doesn't seem to have a choke built in. So as you guys said above, just put your finger over the carb opening and pull to prime the engine (so your finger is the choke, I guess). Is this how the mod engines are made (or at least how this one is made)? What's the advantage of no choke or am I suppose to add one on and this is just a bare bones engine?

Thanks, Tow.

Status: offline 		well I started my venture tonight in reinforcing the boat/adding some weight, I have posted plenty of pics, I did find one thing that kinda irked me, the radio box was cracked and superglued back together from the factory, that'd be why I kept getting water in there when there was water in
