Great, we will wait for you to put everything back and wait for the pictures of your complete installation of things.

Sorry, posted twice. Ok then, I want to do a float bowl check before I wrap the carb up. What's the best way to measure the float? The needle is doing it's job. Need to check the float height don't I? I just now adjusted the valves, I used .004 and .005, intake,exhaust, ok? Compression tester part didn't come so have to wait for a compression test. Oh, the valves were .001 off on both. Sorry, waiting for manifold gaskets also, O ring and regular gasket, not both O rings, go figure? Guess it will be Monday or Tuesday so I don't want to hold you up waiting for me. I'll post and let you know about the pics. Need Bashan to help me post them, I'm on Photobucket and Bashan can work with me on that, so, Thanks and I'll keep you posted.

I've been up to my ears trying to help alleyoop help me. Just about ready to take some pics. A little off subject, I have a question. What is the proper gap for the intake and exhaust valves? I've been fed some info about that, not from scooter doc, but the worry wart in me wants to pin down the right numbers. I'm not questioning what scooter doc people have told me, I just want to verify that I've remembered right, and that this last info I've gotten is all BS. It comes from a scooter shop tech, but he's been wrong before, I've proved it with my results. He doesn't make sense a lot of times. I didn't ask him for this info, he asked what setting I used and I told him what I had been told and he said that was wrong, I don't believe it. Did he mistake mm's for thousands? That's being nice. Anybody? Thanks to all.

You already adjusted them INTAKE to .004 inchs or .08mm and EXHAUST to .004 or .005 inchs or .10mm.
I adjust my 150cc 157QMJ motor to .004 inchs both intake and exhaust. Some do .005 inchs on the exhaust because that is the one that closes up faster due to the extreme heat it takes.

Thanks alley that just confirms what I thought. I really should check first but the parts sites say I have a BN type motor. the numbers have a 1p58 and letters but they are not qmj I don't believe. Sorry, I'll check that out but I know people say it's BN. what does that do for the valve gap? anything? just give me a shout I don't want to make a big deal out of it and waste your time. Let me know. Thanks.

PS what was that tech thinking?

[Alleyoop]

You have the 1P58MJ motor valves sameo sameo, if they clatter at that setting just re-gap 1 mm less a ticky ticky is good you then know they are not to tight and not to loose.
