 This is the 150cc Vento I rescued from a river it was pink and silver with a lot of brown muck, now it's red white and blue and running great thanks to this board and Alleyoops' help. Living the motoneta dream in Mexico. Cheers... |

Many many THANKS for helping me out with the Vento all's good now and your help was invaluable. I have another project LOL a 150 Vento frame that has Aprissa plastics and a 175cc Italika motor, all's running good just missing 12v at the rear light cluster. Brake light and indicators work ok but no tail (running light) or license plate light, does this feed go through the magneto and or rectifier before it gets back to the bulbs? Maybe I will have to replace those parts too.

Checked fuel to carb, took hose off and cranked, NO fuel came out. When I reconnected hose to carb and cranked I could see gas flowing into the transparent filter, but obviously not enough! When I checked the carb, the bowl had gas and all the orifices were clean. So I assume I just need a new petcock to let the gas run more freely. BTW the fuel air was just one turn out so it's now at two and a half as you mentioned.
Will try again tomorrow if anybody in this country has a new petcock on the shelf, if not it's two weeks waiting.
Cheers

Ok, exhaust and air box on, spark from plug at valve cover not frame, took out the line with fuel filter and replaced with straight rubber just in case it's the buck fifty fuel filter. Yes have compression, enough to force my thumb form the hole.
Spark plug is DRY so how do I fix the sucking problem? Is it the petcock or a hose, what's a simple test?
BTW I don't have feeler gauges so I can't check the valve clearances, right now it's off season here and I won't have a job till November so gauges and clearances will have to wait.
Cheers

Yessir indeed, Motor back together and in, I am sure I have the cam and chain right.
Removed the PAIR system, it was all clogged up, have the airbox and exhaust off the motor. Turns over well on the new battery, no mystery noises or clanging, seems to be in the right configuration, all the gas/vacuum hoses are in the correct places, dismantled and checked all the carb internals, all ok, got fresh gasoline and a strong spark but it wont start.
Just about ready to give up and take it to my local Italika bodge artist spanner boys here in the village. I live in Mexico by the way. I have tinkered with real motorcycles all my life (31 years riding) but this is my first scoot I cannot get running, I have repaired and sold three of them recently, just badly looked after and neglected.
Any suggestions would be appreciated.
Mike

Thank you very much, Alleyoop, you have put my mind to rest. I bought a 5 year old vento that had been in a river for some time and so far all I have had to do to it is general cleaning, change the camshaft and today I will be changing the gasoline for some fresh stuff and seeing if it will run. Fingers and everything else crossed.  |

Where in relation to the rotation limiter does the cog/lug on the camshaft sit when re assembling or does it automatically locate itself? I am not sure if I have it correct. I have used photos from bashrans thread on this forum to hopefully show what I am talking about. Many thanks all esp Bash for his really infromative thread on dis and re assembly. This photo shows the rectangular cog/lug.  This one shows the rotation limiter  |
