Please Help, My Kart Is A Disaster

Ooh... really? I must be behind the times haha!

Oh yeah... Raptor Kits...

Haha. Yea, flatheads are what got me started in this hobby. Simple as to work on and have great performance. Look at the Ford (ewww) flathead v8 from 1932, people are still building them! In fact the French army used them in their equipment up until the early 90's! That concludes today's history lesson (sorry for the hijack).

I agree with an extreme rich condtion. Try this: screw in the mixture screw on the carb until it bottoms out. Then screw it back 2 1/2 turns and fire it up. Then adjust it accordingly to where the engine runs best but only go a 1/4 turn at a time either way. An engine builder told me this, and it's what I do every time a carb gets taken apart. Let me know if this helps.

Simple?! I hate gettin those heavy springs in... OHV's are a bit easier, but give the same pain in the arse.

In design, yes. Especially to some EFI DOHC engines that are out there (I work on cars too ) You need a spring compressor.

You sure you're a "kid"? Haha!

I do have a spring compressor, however, the space left is too small to even fit your pinky in. This is compressing the spring to its maximum (and the compressor...)

And this method doesn't worth with OHV's either...

Oh, the springs are a pain in the , I just don't really remove so many that it becomes an issue. And that's exactly what they said on another small engine forum I'm on....I had to show a pic to prove it!

I had some luck with a wire stripper, magnetic stick thing, and those spring compressors...

You compress the spring, and barely put it inside for the valve to get into it... then use the magnetic stick thing and get the retainer on correctly, but not in its slot. From there, stick the wire strippers in, there's a small hole in the middle (or mine did, if yours didn't, just open it up a bit), release the compressor (will have to use some force to pull out, keep the wire strippers bent a bit to keep the retainer on the valve, and hold it!)

Then just bend the strippers a bit, *clink* job done. This worked amazingly the first time I used it. I'll try it again when I'm doing my 3.5 and 5...
