Alright, where are the guys that are a little better at reading these things at? I am not sure what to look for

 

MRDS - Have you sent these to Eric? Some of them are too small for my old eyes to read but I think I can make out the A/F and they are terrible.

Your peak A/F ratio is ok, borderline lean, but you spend very little time at a decent number during the RPM range. The majority of the time you are rich.

I would definately start by leaning your metring rod a half turn and see what results. I would also order a 90, 110 and a 120 powerjet. My guess is you will not be running more than a 90 but jets are cheap and if for some reason your motor wants more fuel up top, it would be silly not to have them.

 

I did send the graphs to Eric and he knew there was something wrong but we are trying to figure it out.

Am i best to get power jets from Eric or is there another supplier ?

Thanks for the help again guys

 

Hey Guys

I reposted my dyno results in full size form, should be easier to read. Also included the Torque readings.
Thanks for the Help in advance.

Did you try lowering the float bowl level?

Fuel curve is not consistant thru mid range, yet leans out at top.
Now I see why #100 powerjet gives the bests top power.

It appears even before head work was done, that carb was not dialed in.

I have never even had the float bowl off the carb before. What would adjusting the float bowl level do? How do you adjust the bowl level.

The carb seems to be full of full - it has a clear bowl ???

With float bowl(18) in hand, measure from top of float bowl surface to top of each float(19). Record. Bend each float down .060, they should also be the same depth.
As floats are deeper, the pad between floats and pin(13) will hit the needle seat(21) sooner.

The Lectron carb is made from castings that were designed 25 years ago.
Even though they never state to adjust the float, even Eric will state that correct fuel height is critical to this carb. What is the correct height? Simply- If erratically lean - Raise Ir erratically rich - Lower

The Link does not work, can you repost please.

Thanks

 

Bump - Edited

 

So the floats will hang .060 of an inch down with out the flaot bowl installed Right?

You also said that even before the head work my carb was not dailed in, I thought it ran ok, but i take it it should stay in that 12.5 to 13.5 air fuel maixture right ?
