bashplate Posted December 29, 2018 Report Share Posted December 29, 2018 Hey 175 guru's, just getting a 1976 up and running again. Starts first kick and ticks over like a swiss watch....but open throttle past 1/4 and it just dies out. Is this the classic "o" ring around the main jet problem, or something else. Carb has been stripped and carbie clean/airline blown out. Quote Link to comment Share on other sites More sharing options...
feetupfun Posted December 29, 2018 Report Share Posted December 29, 2018 Could be, but not enough info to know for sure. How quickly is the throttle being opened? What happens when you try it with the starting circuit in service? It is doing the same thing hot and cold? Quote Link to comment Share on other sites More sharing options...
bashplate Posted December 30, 2018 Author Report Share Posted December 30, 2018 Yeh, does it hot or cold. If turn throttle gently in lower gears up to 1/4 open, then motor revs cleanly, but go any more and will balk. Quote Link to comment Share on other sites More sharing options...
Bmonk Posted December 30, 2018 Report Share Posted December 30, 2018 Yes it's the classic o ring around the main jet holder Quote Link to comment Share on other sites More sharing options...
bashplate Posted December 30, 2018 Author Report Share Posted December 30, 2018 Thanks Bmonk, I'll grab 1 when the dealer opens in New Year.....or will any 'o' ring the right size stand up to the fuel? Quote Link to comment Share on other sites More sharing options...
feetupfun Posted December 30, 2018 Report Share Posted December 30, 2018 I usually just tell the person behind the counter what it's for and they sell me an o ring made of the right stuff 1 Quote Link to comment Share on other sites More sharing options...
