atcandbanshees Posted April 27, 2013 Report Share Posted April 27, 2013 New to alky. Have a 4mm drag ported by k&t bought carbs that came off 10mm cub and is just pooring fuel in the cylinders when sitting and blowing raw alky out the pipes when running. Any ideas?

#1JUANstunna Posted April 27, 2013 Report Share Posted April 27, 2013 17-19mm is the float heights from the gasket mating surface. Quote Link to comment Share on other sites More sharing options...

#1JUANstunna Posted April 27, 2013 Report Share Posted April 27, 2013 Take them apart and clean them real good and check the float height. Quote Link to comment Share on other sites More sharing options...
atcandbanshees Posted April 27, 2013 Author Report Share Posted April 27, 2013 When I get it to rev up and cleaned out I can launch and then it just falls on its face and almost dies I have to play with the throttle to keep it running.

#1JUANstunna Posted April 27, 2013 Report Share Posted April 27, 2013 Brandon recommended to me for a starting place: 6DP4 needles, Dumps .118, Mains .116, and clippard at .089. Quote Link to comment Share on other sites More sharing options...

#1JUANstunna Posted April 27, 2013 Report Share Posted April 27, 2013 That's a possibility, you might pull off your pipes and make sure they aren't full of alky too. Quote Link to comment Share on other sites More sharing options...
J-Madd Posted April 27, 2013 Report Share Posted April 27, 2013 Are running a pump? Quote Link to comment Share on other sites More sharing options...
#1JUANstunna Posted April 27, 2013 Report Share Posted April 27, 2013 Are running a pump? That reminds me! Mine had the wrong needle and seat for gravity flow carbs. You might pull out the seat and see if they are 1.8mm (pump) or 3.5mm (gravity). It's right on the underside after you pull them out.

atcandbanshees Posted April 27, 2013 Author Report Share Posted April 27, 2013 No pump. The 10mm it was on didn't have a pump either Quote Link to comment Share on other sites More sharing options...
