1974 Chaparral ssx 340/440 carb main jet size
« on: February 05, 2013, 01:04:05 am »
Hi Everyone, I have picked up 2 new projects a 340 and a 440 Chaparral SSX, they both are is fine shape with the typical cleaning and painting, and..... the carbs, so after searching and searching I have come up with someone on here with 200 main jets in  the 440. So I go looking at the carbs on the 440 it has 170 pto and a 240 in the mag. :o so I check the 340 it has 360 pto and 390 mag :o :o. Does anyone have the stock jet numbers so I can start jettin from a safe start. I have put new carb kits in both sleds.

Thanks

    I run 190-200 mains on my 440 SSX but I ride at 6000 feet. Try MFG supply for carb kits.
