PeeWee woes...

What fuel are you running?

glow plug boy

Travis,

Man this is frustrating.....wish I had teleporter like in Star Trek.

Anyway if it spins free I don't see it being a problem. What you are probably feeling is heat radiated to the case from the cylinder.

Does your piston go through the cylinder easily now? It should either fall through or at least push through with very light pressure. If not then that needs to be corrected.

Last night I was cleaning up a pee wee and I noticed the piston crown was hanging up really bad just at the top of the exhaust port. I took some very fine steel wool and cleaned all the yellow varnish out of the cylinder and cleaned everything afterwards. I then polished and oiled the piston and it slid right through the cylinder and landed on the floor!

Something to check anyway. You may have a warped cylinder and devarnishing won't fix that.

YO Travis,

I knocked this one out of a spare front end I had, and it looks to match the one on the left in your photo. I'll pack it and the rest of the junk along tomorrow.

I can also bring you some fresh SIG 25% and 35% to muddy the waters even more !!!

Have you cleaned out the groove that carries oil down the length of the crank? I got a nice looking used Black Widow the other day and the groove was so gummed that it would have scorched the crankshaft if I had run it without checking. I had to use a dentist's pick and brake parts cleaner to clear it out.

awesome Kim!

Kim brought me one to try when he picked up the traveling prop yesterday. I'll let you guys know how it goes.

Yeah man, please do. I am interested in the fix action on this one.

A semi plugged needle orifice will choke your motor, kinda like what you are describing,,if I read all that correct.

A lot of people commented over and over trying to help. What's the status? What was wrong? What happen ect???

I'll play with it tonight to see what it does. I've spent way too much time on this little engine to give up now


As for now, starting cold seems to run fine. The the longer it runs, through the initial tank, the more doggy it gets (like with a throttle ring on idle). It will eventually die and when you try to start it, it may run only for a few seconds. It will get to the point that it don't want to start except with a shot of prime. Let it cool down and your back to square one. That's why I think the shafts are causing it to overheat and not run. The head is too hot to touch and the case is almost to that point. I've tried the tank from my good one and it does the same thing.

I'll take a look at the case also when I have it apart to see if there is something clogged there.

Have you checked the actual thrust bearing surface? I'm talking about the part in the crankcase that the front part of the crank disk pushes against as the engine runs.

Are you making a bunch of aluminum "mud" on the snout from the drive washer??. Could be a really close drive washer when pulled on.

Once everything expands from a touch of heat, it takes it out of tolerance possibly.

I'll never know, I just egged the cylinder trying to get the glow plug off. I'm not to happy.

Ouch!

What happened? The head must have been on really tight. Sorry to hear that. Good thing is Cylinders do pop up on Ebay now and then. See if Joe has one for ya.

hey, jason_wi has peewee cylinder/pistons i think he only has one set for $10, pm him he can help

Give that piston/cylinder set I left a shot. You're welcome to it if it works ! Apparently gonna have to tear down the .020 in my Mini Stunt. I'd hoped I'd luck out and just have it crank up and run, but it's not steady, needle setting is all over the place. Time for a de-gooping !!!! The Pee Wees are NOT being friendly this month !!!!

I scared to try and start mine now.

The #3 engine isn't the same cylinder I'm messing with, should be fine. I still need to get it in the mail and off to you.
