I just rebuilt codys lt 80 and replaced his carb, which was already a 20 mm, it was just flooding like it had a stuck float or something. Anyways I had a brand new one so I replaced it without checking what it was jetted at. Now his quad is bogging bad at a take off and running rich. Also it no longer needs the choke when its cold to start it. He went from running 8.00 seconds to high 13's at a 100 yards.
Does anyone know what DG puts in their carb kits as fa as jets go? I kept the needle at the same setting. It seems to run better at mid to top range,help please, I am not good with carbs[img]i/expressions/face-icon-small-confused.gif[/img]

 

I forget what jets they come with.
I'm thinking 48/115 jets should be close.
Take a look see on what's in there. [img]i/expressions/face-icon-small-smile.gif[/img]

 

were running 48/120 in our moore built lt 80 it had 55/105 in it when we got it. so not sure if thats what they come with or not.but the thing rips now that we put the 20mm on it.

 

I think the best way, which should have been more obvious to me sooner, Is to look at what the old carb was jetted at. Thanks guys for the replies, I'll try it Thursday.

 

Okay its Thursday now, and I went through and cleaned up the old carb and checked what it was jetted at. It was a 98/58. I know that isn't what you are running but it ran great with that combo so.... I'll update later.

 

A 98 should be about right. We ran a 98 to 100 main in ours.

 

if it worked good before then use that we are running what we run cause we have a moore engine with all the mods.

 

I put a 50 in it today as the carb was still bogging but not as bad, I'll keep updating.

 

Okay I re jetted the carb with a 55 piolit and raised the needle up one posistion. the plug looks perfect now, but it still is hesitating on the take off... I ended pulling the front clutch and found the the front rollers had been dried fried and flat. I'll fix that and get back.

 

Well I fixed it, it was the rollers after all. Boy do I feel dumb for missing it from the start. I warned my son that I fixed it probably but he has grown a custom to it hesitating and long story short he flipped it over backwards, oops. Hes okay though.
