plug chops

[pittss1c]

I attached a file with a couple plug chops.

The top 2 are 165s and the bottom 2 are 172s

 

Both times the right side has a larger dark region and it varys a lot in width. The left side is more consistant. Any clue why? I am just trying to get it a little too rich for a starting point.

 

I am told:

The carbs are 28mm PWKs. 4 mil stroker +4 timing cool head w/21cc domes/ dg pipes/mild port

the bottom ones look safest, definatly rich, but if it pulls good and no studers then leave it that way, as to why one side is "larger" then the other i cannot answer but mine was the same (not as much, on mine you could barely notice) i am sure someone with greater experience will chime in

It pulls well with either set. I expect to be running it at higher outside air temperatures. (these were done at 50 deg, and I expect I will run more often at 80)

I am concerned that either the float level is incorrect, or maybe I am starting to run my bowl dry on the left carb during these tests.

running the bowls dry is a possibility, whats your mods, heres a pic of mine at 50* F and well be running at 80-90 just like you

 

these are perfect at 50* so 80-90 ill be just right on the rich side

I can tell you mods that I was told at purchase.

4 mil hot rods stroker crank and rods... cool head with 21cc domes. 28mm PWK carbs, DG pipes, vforce 2 reeds. some mild porting.

 

I'd buy a pingle right now to help eliminate it as a possibility, but don't want to lose the reserve.

[350BANSHEE350]

well you dont need to buy the pingle you can do this http://forums.everything2stroke.com/genera...uel-petcot.html but it eliminates the reserve as well

 

also are your needles the same and same position

I like the mod... I might buy a spare first.

I haven't checked the needles yet...will do.
