flooding?

[Matt84]

After I have warmed the engine, I start to do my full throttle passes. After about the second one, when I bring it in to me, the engine is really hard to keep at an idle. I almost have to keep the throttle on. Sometimes I can get it back by doing a couple more hot laps. I take the air filter off and I can see fuel. I have tried to lean it but I still get the same problems. Is it my tuning skills or something else?
Thanks for reading.

It may be lean on the high side. after your high speed run your crankcase has no residual fuel in it to support the idle. after a period of running on the low to midrange the crancase is sort of resaturated.

When you bring it in is it idleing real high before it shuts down?

after running at high speed, it idles normal, but want to stall. I talked with the local hobby shop guys and they seem to think it might be a seal on my carb. Ill reply with an update shortly.

thanks

Do you have a temp gun/gauge ? If so then check the temp at idle and if the temp rises it would either mean there is an air leak or your too lean,an air leak will cause a lean issue,and bad tuning

It's probably too rich on the low speed needle, but first make sure you have a 1mm idle gap.

thanks

Ok so I got the engine tuned. It was to rich on the low speed needle. Also the brand new glow plug was faulty. Got a new glow plug and the truck is running smooth. Also I just threw a 4x4 kit in to it. Way better. thanks again.

No problem.
