twin 40 jet query

[SRlew]

right as the engine was running bad i thought id check the jets on my dell'ortos.

the left carb seemed fine couldnt see any blocked holes in them or anything then the top roe on the right i took that one out and on one of the holes it has like some black stain on it like somethings popped out of it and exploded then near the bottom of it its like flaired a little and has a little crack in. would that cause the problem i was having?
and were can i get a new one and how much?

you can sort of see the part i mean

cheers lew

you can get them from euro crab ,they have a shop on e bay search for seller euro carb

it will flare a little as the bottom part is a push fit into i reckon the crack is the culprit

Thats an idle jet tho.
Above 3k ish rpm it aint used. So if it runs bad above that, its probably not the cause.
Try cleaning the other jets

[SRlew]

took all the jets out i believe, are there 4 in each carb? 2 that size and 2 longer ones?

[Adam]

Yeah, the smaller ones are idle's.
The larger one is the main stack.

Theres also the accelerator pump, bleed back valve and progression holes that might be worth looking at.

where are these to then lol, what they look like? cheers ad

The pump and prog holes are under two brass screw covers on the barrel itself.
The pump valve is inside the float chamber at the bottom.

Assuming your dhla's are same as my dcoes.
