Hello everyone.Iam new to the fourms my daughter races a modded lt .030 over, works,uni 105 jet port/polish,weisco,boysen,dg pipe,clutch mods,stock carb and box setup,100 octane,40:1 torco bla. bla. bla. I have reading your posts for a while and thought id get in finally.. small problem,just cant seem to figure it out and was wondering if I could get any of your guys opinions on what it could be.When iI run the lt through the band,lowrange is good,mid is also good,but at wot, itcuts in and out done everything petcock is wide open in the right position fuel flow is ok grounds are good plugs good iam swamped.... any advice???

 

Who did your motor and what does he say about it?
I think I may know what's wrong.

 

hey lt. hetrick did the mods and he seemed kinda stumped other than jettin it up and ground issues. it runs strong until wot. then blap....blap ....blap.... then I have to let off. almost seems its starving for fuel. even went as far as taking the internal filter out and going in line..

 

I know he's been telling ppl a 110 main jet. If you have drilled the holes, then that's it for sure.

 

your not talking about air box hole at the top????

 

wanna do my other lt engine????

 

Yes I did drill the hole at the top.. what Ill do is being that this was happening prior to air box modd,mabye Ill slap a 110 see what happens thanks so much Mr. Lt always that little tweak a....

 

If you have a fuel filter check it for restriction.

 

stuck a new one on from napa. man just the little things bite ya..ya know.....
