choking either way  By  scootzy (Read 2,166 times)

Let it warm up before riding or adjusting the carb . Here is some info that may help you www.iwt.com.au/techinfo.htm

to alleyoop:
I just bought new hose for fuel-in, a crack in the old one.
what size of hose do I need? I got 3/16" clear hose and a 1/4" inline stone-like filter, I call it a cartridge type filter.
I will check the vac to petcock! get it pet-cock, ha ha.
The enricher is fine.
everthing's stock. the four hole re-stricktor on the snorkle tube is on, but, modified. do you want pics on modification. it worked well untill I took off the pair sys. I was thinking of putting the pair sys back on and see if that does it.
If you think of anything else.
I am mechaniclly inclined so working on this scoot is no prob. so easy to work on!

Ok, the four hole snorkle cover one hole at a time and see if that helps those 4 hole snorkles let in to much air.

Take that the fuel hose off the carb and put it in a container and then take that vacuum hose and suck on it and fuel should come out of into the container. BUT Watch out sucking on it if it is leaking you will swallow gas, so better use like a baster or something to create suction and then take it off and see if gas comes out the vacuum line as well. If so you need a new Petcock it is leaking.

well lets get one thing at a time figured out. Since you said the Vacuum line is wet that means it is getting sucking in fuel from the vacuum line. So get that confirmed first otherwise that alone will throw everything else off.

alright sound's good, though it will take a few to get one. payday is around the corner.

Alleyoop, The tube I'm talking about connects to #3 in the 4th diag pic on this page:
www.chinese-parts-canada.com/parts_gy6_139qmp.html
the tube that comes off number 3 goes to the canister valve like thing. (Pair)
it's a double vac line intake one line goes to the petcock and the other one goes to the bottom of the canister. now, when wot the vac opens the canister to let the engine breath, i suppose. kinda like a pcv valve, come to think of it. let off trottle valve closes. the top tube coming off of the canister has a filter.

when I took the pair sys off this is what I did. I pluged one vac off intk. re-routed the vac to ptck, instead of the 120* turn it was making and straightened its' path, also shortened the tubing. the big tube coming off of num. 3 on the diag. is now free-flow with the pair filter in line.
if I plug this line she runs with lacking power and wants to die. So, I kept it open (to breath) with the filter in-line

walkthrough:
carb, tube to the air box, air box, filter cage and filter, snorkle tube, and four hole restrict peice.

now the 4hole I cut out. I cut a speaker grill to fit inside the 4hole as a screen. I then cut a small round lock key so when placed on the front of the 4hole 4 holes exist. when placed on the screen it gives a little more air. note: I did this thinking that I had no a/f scrw (before carb clean and found it) and adjusted the air flow this way.

the crankcase vent tube went to the snorkle tube (before the airbox, after the 4hole). I cant plug it and I know it needs to vent. unconnected it, yes, I took a fuel filter and set it in-line.

The diags in the above site are exactly what my engine looks like to the tee.

if there is something I missed then exuse me. I'll write in later.
