Now that all the new carb bits have arrived, and before I start this job, is it really OK for the gaskets to be so far out? Do I just trim off anything that is flapping in the orifice? Oo err!   Are there any other wise tips and tricks for a novice about to embark on his first carb upgrade? (I've done all the carb overhaul items as your previous advice - thanks). |

Poor quality I know...............but hardly unusual these days I'm afraid. You're lucky! When I dismantled my new-to-me PX to check out a two stroke oil leak I found that the bu**er who had rebuilt it some time in the past had fitted a non autolube gasket; that is with no hole so no wonder I had a leak. The result would have been catastrophic had I not added some to the tank as I'd disturbed the auto oil supply pipe for another issue etc. The autolube hole is the small one there by the way. I would use that gasket if I really had no other, but would suggest getting a better one. If you HAVE to use it make sure the opening into the crankcase is not compromised and that when trimmed back still has enough 'meat' to provide a seal.I would also make sure that the auto lube hole was made slightly oval to ensure max flow (if you are still using it of course). Mine appears to be rather a better shape than yours (ooohh err).  |

Thanks for that. I’m not happy with them either, and I’ll start the job when I’ve got it all right and ready – no rush; I’m running fine for now with the 20/20 & 116. I’m rejecting these anyway because I ordered non-autolube gaskets, and because if I trim them there’ll be nothing left. I got them from SIP though, so I thought they’d be good, the gaskets for the carb innards I got are Dell’orto, but these aren’t. I reckon I could do a better job myself, or do you think that’s over the top? I’ve just looked at blank paper gasket sheets, and I see 0.25, 0.5 & 0.8mm thick. Dumb idea or not? I’m inclined to give it a go with a thin sheet. I can also use my template to see how it sits over the hole in the carb box, so I know whether or not I need to take that off to cut it, and then tackle that gasket too.  |

The thicker the gasket the more 'give' there is if the machined surfaces aren't quite perfect/flat.
I have made gaskets out of a Kellogs cornflake box before now (sort of waxy external finish anyway) and they have been just as good as an original and a lot better than the one you have at present !!!

I was about to suggest cornflakes packets, I've used them regularly over the years when stuck, although my best bodge was to use a business card for the selector box gasket. I just cut the middle out and punched a couple of holes in, then left the rest of it showing. I thought it looked good  Oh, and go with the thicker one, you know what vespa tolerances can be like. |

(I've done all the carb overhaul items as your previous advice - thanks). im having the exact same issues sime, is it best to just make one, i got 2 gaskets through the door this morning and are both the same as the one in the picture, where can i buy gasket paper to make it myself? |

Hi Guys what thickness gasket paper do you use please ? I just checked my gasket paper but there is no markings on it to tell you what grade, feels thicker than the carb gaskets i had, i have not had any problems since makeing my own, goodluck. |

hi guys i always make my own gaskets ,a set of craft leather hole punches and a craft knife and a micrometer,the bloody gaskets never seem to line up nowadays and the paper quality is shocking and of dubious thickness....... its also very therapeutic and rewarding ,restoring my xs650 the carb bowl gaskets that came with a refurb kit were frankly junk they leaked like a sieve,and when i measured them they were different thicknesses all over the gaskets ,i made up a couple of new ones no leaks
