I recently acquired a 1980 Peugeot 102 that had been sitting for years. I’m going through the ignition system and ran into a bit of a problem. The service manual from 1969 says timing should be set at 2.5mm btdc for the piston port engines, some people say 1.5mm btdc, others say 1.8mm btdc. What’s the proper timing for a stock 102? Also, I’m looking at ditching the leaky gurtner.. which SHA would be a good match for this bike?
Thanks
Matt
yes to timing, and not sure about putting a dellorto on that long snout intake. best to measure od and id and check if theres a shim that'll work. or maybe theres a custom intake out there, thr orginal id is really small on that intake.
You can install a SHA14:12 on a 102. In the mean time, clean the float valve to stop the carb from weeping.
Thanks for the suggestions guys! I might see if I can salvage the gurtner but failing that I’ll end up splurging on a 14.12 provided I can figure out a decent way to shim it up to the stock intake. I also looked in the owners manual and saw that the 102 has the same ignition timing of 1.5mm btdc as the 103.
Thanks again,
Matt
Shim is only to make up the difference between the OD of the intake and the ID of the carb clamp, you could even fabricate one from a beverage bottle or other plastic. For sealing at the union between carb and intake you can use a oring. 5/8 x 13/16 x 3/32 oring is a great fit into the 14mm bodied carb sizes
