i flow the fuel system each time for the correct hp rating I'm using and I'm running a areomotive eliminator pump for the engine and the two kits the this pump claims 2300 hp Na so aeromotive said it will be good for my system

well when we tried the fogger at 200 i had it taking out 15 degree retard and it went slower then when i had it at 10 degree so i do not think its the retard issue

All I can tell you is that I started at a whopping 100hp shot and slowly worked my way up to a 300hp shot and everytime I increased the jet size it responded correctly. I would not jump fro 100hp to 200hp unless you have a system that was flowed first.

Maybe you have a solenoid or filter issue.

Frank,Weighing the bottle before and after is a great idea.Let me know next time you go out. I have a very accurate digital refrigeration scale you can use.

Here's another case of not enough info ??? Hen you guys say "I'm spraying 100" or 200 or 650 doesn't really tell us anything... :confused:

There are many different systems out there as well as many different tune ups available to guys.. You need to put real numbers on these post to get real info back..

Also you say "i flow the fuel system each time for the correct hp rating".. Does this mean your flowing with a different flow jet each time ???

Please give us somemore info and maybe we can better help you out.. SJ
