Not sure what kind of carb you have, but my first one (66cc/NT) had a leak in the plastic float which allowed gas to get inside it, which weighed it down, which caused gas to flow out of the air filter (through the overflow hole). Changed that and all was well.

I've had one good ride out if my Grubee skyhawk GT5 since finishing the build on Sunday. Yesterday I go to get another ride out of it but I tighten up the exhaust bolts first. Jim, at pedalchopper.com let me know to tighten them up after the first few rides.
Anyway I'm tightening the bolts and notice one bolt isn't locking. Long story short I back it out and shine a light into the hole and its nearly threadless.
Afterwork today I'll be getting a tap&die set and getting it back to running.

That suck Resetman, you should just get a single tap for like $5 now, and wait for the whole set when they go on sale. $_$


Being the first day of Spring(woo!), got in the mood to tinker on something. Will be doing a reverse jug mod for the 29er with a replacement engine after the aluminum can head gasket debacle... (still gotta split that case to get all the fragments out, hopefully salvage it)

So, started with cleaning the transfer ports. They were maybe 85% open due to slag... bleh. She'll be a happy camper now:

Killercanuck that does suck. I already got a set from work I'm gonna borrow for the job. It being the first day of spring I would rather be riding it after work! Good luck with that tinkering you got going on.

I've found that if you screw the stud in tight then it has nowhere to go when things get hot and start expanding. If the stud is already bottomed out then when it expands it has nowhere to go except harder against the threads and tends to strip them out easier. I run the stud down, then crack it back just a little. I haven't stripped out a stud since I've been doing it this way.

Fatdaddy I'm gonna take that advice once I get that hole re-threaded. I wanted to get to it afterwork but you know how issh* comes up and plans get averted. Looking like its gonna be a weekend thing but its cool because I'll have more time to get it right.
On the plus side though I did get my rear fender cut to stop that chain from rubbing it on the engine side. So that's why I did to my bike today.
Has anyone done something different to stop their chain from rubbing?

Got a right angle adapter for my dremel. C:

I'll have to see how well I can use it to get at the transfer ports.

Put a piranha throttle on the cruiser

Fiddled with the mountain bike, jetting and re-jetting the RT carb, switching back to an NT carb, changing fuel ratios, searching for air leaks... and still not able to keep the engine from bogging down on hills

Thinking about swapping engine with a spare I have laying around.
